Ford’s Legacy of Power and Innovation: The Mechanical Hardware Map of Bronco Trim Levels and Gear Ratios

You’re scrolling through Ford’s website, comparing the Badlands to the Outer Banks, and suddenly you’re drowning in alphabet soup—HOSS, Sasquatch, AdvanTrac—and wondering if “4.70 axle ratio” is something you should care about or just marketing fluff.

Table of Contents

Here’s the truth: under the skin of every 2026 Ford Bronco lives a mechanical map of gears, differentials, and suspension hardware that’s radically different depending on which trim you pick. The difference between a Base model and a Raptor isn’t just leather seats and badges—it’s a completely different blueprint of metal and lubricants engineered for specific types of adventure. And yes, those gear ratios matter more than you think.

TL;DR;
The 2026 Ford Bronco offers a mechanical smorgasbord across seven trims, with gear ratios ranging from 3.73 to 4.70 depending on engine, transmission, and optional packages . The Sasquatch Package is the great equalizer—slap it on almost any trim, and you get 4.70 gearing with locking differentials front and rear . The Badlands stands alone with its front stabilizer bar disconnect and HOSS 2.0 suspension . The Raptor lives in its own universe with a reinforced frame, 4.70 gearing, and Fox Live Valve shocks . Manual transmission fans get a unique 4.46 final drive with a crawler gear that makes rock crawling a breeze .

Key Takeaways

Gear Ratios Tell a Story: Higher numbers (like 4.70) mean better crawling and off-road torque multiplication. Lower numbers (like 3.73) mean better highway fuel economy .
Sasquatch Changes Everything: For roughly $6,000–$8,000, the Sasquatch Package adds 35-inch tires, 4.70 gearing, and locking differentials—turning any trim into a trail monster .
Manual vs. Automatic: The 7-speed manual includes a “crawler gear” (1:6.588) that’s essentially a dedicated low-low for technical terrain, paired with a 4.46 final drive .
Badlands is the Rock Crawler King: Only the Badlands offers the front stabilizer bar disconnect, giving you maximum wheel articulation for boulder fields .
Raptor is a Different Beast: With 4.70 gearing, 37-inch tires, and 440 lb-ft of torque, it’s built for high-speed desert running, not technical crawling .

Decoding the Numbers: What Gear Ratios Actually Do

Ever wonder why some Broncos feel punchy off the line while others cruise effortlessly at 80 mph?

Let’s get mechanical for a minute—but I promise to keep it painless. Your Bronco’s axle ratio (that number like 3.73 or 4.70) is the relationship between the driveshaft rotation and the axle shaft rotation. Higher numbers mean your engine spins more times to turn the wheels once. That gives you more torque multiplication at low speeds—perfect for crawling over rocks. Lower numbers mean the engine loafs at highway speeds, saving fuel.

The Math of Crawling:

4.70 gears with 35-inch tires = 3,000 RPM at 70 mph (roughly)
3.73 gears with 35-inch tires = 2,400 RPM at 70 mph (better mpg, less grunt off-road)

But here’s where it gets interesting: your transmission gear ratios work together with the axle ratio. The 7-speed manual’s “crawler gear” (first gear) is a ridiculously low 4.283:1 . Multiply that by a 4.46 axle ratio, and you get an effective crawl ratio that makes steep descents feel like flat ground.

The Trim-by-Trim Mechanical Breakdown

Let’s walk through the 2026 Bronco lineup and see what hardware lives under each one.

Base Trim: The Blank Canvas

MSRP: From $40,495

The Base trim is where it all starts. You get the 2.3L EcoBoost I-4 making 300 hp and 325 lb-ft of torque with premium fuel . The standard transmission is a 7-speed manual (yes, seven—with that dedicated crawler gear), though you can opt for the 10-speed automatic.

Gear Ratio Details:

Manual transmission: Final drive axle ratio of 4.46
Automatic transmission: Final drive axle ratio of 3.73 (standard)
With Sasquatch Package: Jumps to 4.70 front and rear

The Base rides on 16-inch steel wheels with 32-inch tires stock. The suspension is standard—no fancy Bilsteins here. But here’s the beautiful thing: you can add the Sasquatch Package and get 4.70 gears, locking differentials, and 35-inch tires, essentially building a budget rock crawler.

Pro Tip: The Base with Sasquatch is the favorite of hardcore off-roaders who plan to customize anyway. Why pay for leather seats you’re going to cover in mud?

Big Bend: The Comfortable Middle Child

MSRP: From $40,995

The Big Bend shares the same mechanical bones as the Base but adds creature comforts. You still get the 2.3L standard, with the same gear ratio options. The 10-speed automatic’s gear ratios are worth noting:

10-Speed Automatic Ratios:

First: 4.71
Second: 3.00
Third: 2.15
Fourth: 1.77
Fifth: 1.52
Sixth: 1.27
Seventh: 1.00
Eighth: 0.85
Reverse: 4.88

This transmission is a marvel of engineering—those closely spaced lower gears keep the engine in the power band whether you’re crawling or accelerating. The 0.85 eighth gear is an overdrive for highway cruising.

The Big Bend comes with 17-inch aluminum wheels and all-terrain tires stock. The suspension remains standard, but you can add the Sasquatch Package here too, transforming the mechanicals entirely.

Outer Banks: The Highway Star

MSRP: From $48,090

The Outer Banks is where things get interesting. This trim is available with the optional 2.7L EcoBoost V6, pumping out 330 hp and 415 lb-ft of torque . That extra torque changes how the gearing feels.

With the 2.7L, you’re getting the 10-speed automatic only—no manual option. The standard gearing is 3.73, which makes sense because the Outer Banks is designed for drivers who spend as much time on pavement as off it. But here’s the cool part: you can still add Sasquatch.

Sasquatch on Outer Banks:

4.70 gearing
Electronic-locking front and rear axles
35-inch tires
Bilstein position-sensitive shocks

This combination gives you luxury interior amenities with legit off-road hardware. It’s the “have it all” build.

“The Outer Banks with Sasquatch is the sweet spot for someone who wants heated leather seats and the ability to conquer Moab on weekends.”

Badlands: The Rock Crawler’s Dream

MSRP: From $48,890

Now we’re talking. The Badlands is mechanically unique in the Bronco lineup. It comes standard with the HOSS 2.0 suspension system (High-Performance Off-Road Stability Suspension) featuring Bilstein position-sensitive dampers .

What Makes Badlands Special:

Feature	What It Does
Front Stabilizer Bar Disconnect	Allows front suspension to drop fully for maximum articulation—only on Badlands
HOSS 2.0 Suspension	Position-sensitive dampers that stiffen up as they compress
Upfitter Switches	Pre-wired for lights, winches, air compressors
Marine-Grade Vinyl	Hose out the interior after mudding
7 G.O.A.T. Modes	Adds Rock Crawl and Baja to the standard five

Gear Ratio Options:

Manual transmission: Standard 4.46, available 4.70 with Sasquatch
Automatic transmission: Standard 4.46 (yes, higher than other trims), available 4.70

The Badlands comes standard with 33-inch tires and a 4.46 final drive—even with the automatic. That’s because Ford knows Badlands buyers are actually going to use the off-road capability. The 4.46 gears with 33s give you excellent crawl ratio without needing to jump to 35s.

One forum member noted: “The Badlands with the manual and 4.46 gears is unstoppable on technical trails. That crawler gear plus the stabilizer disconnect means I’m never the guy needing a winch.”

Heritage Edition: Retro Looks, Modern Guts

MSRP: From $51,625

The Heritage Edition is built on the Big Bend architecture but comes standard with the Sasquatch Package . That means you’re getting 4.70 gearing, locking differentials, and 35-inch tires right out of the box.

Available with either the 2.3L or 2.7L engine, the Heritage Edition pairs that serious hardware with Oxford White wheels and retro badging. It’s the perfect blend of form and function.

Raptor: The Desert Runner

MSRP: From $79,995

The Raptor isn’t just another trim—it’s a fundamentally different vehicle. Starting with a reinforced frame, the Raptor gets the 3.0L EcoBoost V6 making 418 hp and 440 lb-ft of torque .

Raptor Mechanical Highlights:

Component	Specification
Engine	3.0L Twin-Turbo V6, 418 hp @ 5750 RPM, 440 lb-ft @ 3250 RPM
Transmission	10-speed automatic (same ratios as other trims)
Axle Ratio	4.70 front and rear
Tires	37-inch (LT315/70R17)
Suspension	Fox Live Valve semi-active dampers
Frame	Reinforced compared to standard Broncos
GVWR	6,100 lbs

The 4.70 gearing with 37-inch tires is perfectly matched to the 3.0L’s power band. In Kuwait-spec models, the Raptor makes 400 hp and does 0–100 km/h in 5.8 seconds . That’s legitimately fast for a 5,000-pound SUV.

The Raptor’s suspension is the real story: Fox Live Valve continuously adjusts damping based on terrain, reading the trail ahead hundreds of times per second.

Stroppe Edition: The Collector’s Piece

MSRP: $69,995

For 2026, the Stroppe Edition is four-door only . It’s mechanically similar to the Badlands with the 2.7L engine, but with unique graphics and trim. Gearing is the same 4.46 standard or 4.70 with Sasquatch.

The Sasquatch Package: The Great Equalizer

The Sasquatch Package deserves its own section because it transforms the mechanical character of any Bronco it touches. For roughly $6,000–$8,000, you get:

4.70 front and rear axle ratios
Electronic-locking front and rear differentials
35-inch tires (LT315/70R17)
Bilstein position-sensitive shocks
High-clearance fender flares

The 4.70 Difference:
A 4.70 axle ratio means your engine spins about 15% faster at highway speeds compared to a 3.73-equipped Bronco. That’s the trade-off for having massive torque multiplication at low speeds. When you’re crawling over boulders, that 4.70 gear—combined with the 10-speed’s 4.71 first gear—gives you an effective crawl ratio that lets you idle over obstacles.

Ford Performance offers the 4.88 ring and pinion as an upgrade for those who want even more crawling capability, though it’s designed for the M210 front drive unit .

Manual vs. Automatic: The Gear Ratio Story

The 7-speed manual transmission is a fascinating piece of engineering. Here’s how it breaks down:

7-Speed Manual Ratios :

First (Crawler): 4.283
Second: 2.365
Third: 1.453
Fourth: 1.000
Fifth: 0.776
Sixth: 0.646
Reverse: 5.625

Final Drive with Manual:

Standard: 4.46
Sasquatch: 4.70

Multiply first gear by the final drive, and you get:

Standard crawl ratio: 4.283 × 4.46 = 19.1:1
Sasquatch crawl ratio: 4.283 × 4.70 = 20.1:1

That’s legitimately low—low enough that you barely need to touch the brakes on steep descents.

10-Speed Automatic with Sasquatch:

First gear (4.71) × 4.70 = 22.1:1 crawl ratio

The automatic actually has a numerically higher crawl ratio because of that 4.71 first gear. But manual fans will argue that the control of a clutch is worth more than the numbers.

Torque Curves and Real-World Feel

Numbers on paper don’t tell the whole story. Here’s how these mechanical combinations feel from the driver’s seat.

The 2.3L with 4.46 Gears (Badlands Manual)

This combination is a crawler’s dream. The engine makes peak torque at 3,400 RPM , and with the 4.46 gearing, you’re in that sweet spot at low speeds. The crawler gear means you can let the clutch out and idle over obstacles without touching the throttle.

The 2.7L with 3.73 Gears (Outer Banks Auto)

This is the highway cruiser. The 2.7L’s 415 lb-ft of torque means it doesn’t need steep gearing to feel punchy. At 70 mph, the engine is loafing along at low RPM, sipping fuel. Add Sasquatch, and you trade some highway refinement for off-road capability.

The Raptor’s 3.0L with 4.70 Gears

This is the performance sweet spot. The 3.0L makes peak torque at just 3,250 RPM , and the 4.70 gearing puts that torque to the ground immediately. With 37-inch tires, the effective gearing is actually taller than it looks—but the engine has enough grunt to spin them easily. The 0–60 mph time of around 5.8 seconds confirms this is a seriously quick setup.

“The Raptor’s gearing is perfectly matched to its mission: enough torque multiplication to launch out of corners in Baja mode, but not so steep that you’re bouncing off the limiter at 110 mph.”

The Differential Story: Open, Limited-Slip, and Locking

Gear ratios are only half the story. What you do with that power matters just as much.

Open Differentials (Base, Big Bend without Sasquatch)

Power goes to the wheel with the least resistance. Great for dry pavement, useless off-road.

Electronic-Locking Differentials (Sasquatch, Raptor, Badlands optional)

Flip a switch, and both wheels on an axle spin together. If one tire is in the air, the other still gets power. This is the gold standard for off-road.

Limited-Slip (Not common on Broncos)

Some trims have mechanical limited-slip diffs that transfer power to the wheel with grip without needing driver input. Less common on Broncos than lockers.

G.O.A.T. Modes: Software Meets Hardware

The Terrain Management System (G.O.A.T. modes) adjusts how the hardware behaves. Each mode changes:

Throttle response
Transmission shift points
4×4 system engagement
Differential behavior (if equipped with lockers)
Stability control intervention

Mode Breakdown by Trim :

Base/Big Bend/Outer Banks: Normal, Eco, Sport, Slippery, Sand
Badlands/Heritage: Adds Rock Crawl and Baja
Raptor: Adds Baja mode with specific tuning for high-speed off-road

Rock Crawl mode engages the locking differentials (if equipped) and uses the lowest possible gearing with precise throttle control. Baja mode firms up everything and holds gears longer.

FAQ Section

1. What’s the difference between 3.73 and 4.70 axle ratios in the Bronco?
The axle ratio determines how many times the driveshaft turns to rotate the wheels once. 3.73 means the driveshaft turns 3.73 times per wheel revolution—better for highway fuel economy. 4.70 means 4.70 turns—better for off-road torque multiplication and crawling. Sasquatch-equipped Broncos get 4.70 gearing .

2. Which Bronco trim is best for rock crawling?
The Badlands is specifically engineered for technical rock crawling. It features the front stabilizer bar disconnect for maximum wheel articulation, available 4.70 gearing, and upfitter switches for accessories . Add the Sasquatch Package, and you have locking differentials front and rear.

3. Does the manual transmission affect the gear ratio?
Yes. The 7-speed manual includes a dedicated “crawler gear” (first) with a 4.283 ratio . Combined with the 4.46 final drive, this gives you an excellent crawl ratio for off-road use. The manual is available on Base, Big Bend, Badlands, and Heritage trims.

4. What makes the Raptor’s mechanical setup different?
The Raptor has a reinforced frame, 3.0L EcoBoost V6 making 418 hp, 4.70 gearing standard, Fox Live Valve suspension, and 37-inch tires . It’s built for high-speed desert running rather than technical crawling, with Baja mode and semi-active dampers that adjust to terrain.

5. Can I add the Sasquatch Package to any trim?
Sasquatch is available on most trims, including Base, Big Bend, Outer Banks, Badlands, and Heritage . It adds 4.70 gearing, locking differentials, 35-inch tires, and Bilstein shocks. The Raptor has its own unique setup and doesn’t use the standard Sasquatch Package.

6. What is the front stabilizer bar disconnect, and why does only Badlands have it?
The stabilizer bar disconnect allows the front suspension to droop fully when off-road, keeping tires in contact with the ground over uneven terrain. Badlands is the only trim with this feature because it’s specifically designed for technical rock crawling . Other trims can add aftermarket disconnects, but only Badlands has it factory-integrated.

7. How do G.O.A.T. modes interact with the mechanical hardware?
G.O.A.T. modes change throttle mapping, transmission shift points, 4×4 system behavior, and differential locking strategies . For example, Rock Crawl mode (Badlands and Heritage) engages lockers and uses the lowest gears, while Baja mode (Raptor) firms up suspension and holds gears for high-speed off-road.

8. What’s the crawl ratio on a manual Bronco with Sasquatch?
With Sasquatch’s 4.70 gearing and the manual’s 4.283 first gear, the crawl ratio is approximately 20.1:1 . This means the engine turns 20.1 times for each wheel revolution—excellent for slow-speed crawling.

9. Does the 10-speed automatic have the same gear ratios across all trims?
Yes, the 10-speed automatic (10R60/10R80) uses consistent gear ratios: 4.71 first, 3.00 second, 2.15 third, 1.77 fourth, 1.52 fifth, 1.27 sixth, 1.00 seventh, 0.85 eighth, and 4.88 reverse . The difference comes from the final drive axle ratio and transfer case.

10. What’s new for 2026 in terms of Bronco mechanical hardware?
For 2026, the Stroppe Edition is now four-door only . The Badlands no longer includes the front stabilizer disconnect as standard—it’s optional or included with Sasquatch . New colors include Avalanche and Wimbledon White. Gear ratios and mechanical specs carry over from 2025.

11. Can I change my Bronco’s gear ratio after purchase?
Yes. Ford Performance offers ring and pinion sets like the 4.88 ratio for the M210 front drive unit . However, this requires professional installation and is not a DIY job. Regearing can improve off-road capability but may affect fuel economy and speedometer accuracy unless recalibrated.

12. How do I find my Bronco’s specific axle ratio?
Check the door jamb sticker for the axle code, or look for the metal tag on the differential housing. You can also decode your VIN or check the window sticker if you have it. Broncos with Sasquatch Package will have 4.70 gearing.
