Ford Bronco Off-Road Terms Explained: Angles, 4-Low, Lockers & More

Ford uses a lot of off-road terms that sound similar but describe different parts of the truck's capability. Approach angle, crawl ratio, lockers, 4-Low, ground clearance, and water fording all measure something different.

This guide explains the common terms in plain English and uses Ford's 2026 Bronco specifications where a number helps.

What Is Approach Angle?

Approach angle is the steepest slope the front of the truck can meet without the bumper or lower body touching the ground.

For 2026, Ford lists 35.7 degrees for a Base 4-door, 43.3 degrees for a 4-door with Sasquatch, and 47.2 degrees for the Raptor.

Bumper shape can change the clearance you have at the front. Our full guide to approach angle explains how to read it.

What Is Breakover Angle?

Breakover angle measures how sharp of a crest the truck can cross without the middle of the underbody touching down.

For 2026, Ford lists 19.6 degrees for a Base 4-door, 26.3 degrees for a 4-door Sasquatch, and 30.8 degrees for the Raptor.

Shorter wheelbases usually help breakover angle, which is why a 2-door can have an advantage here.

What Is Departure Angle?

Departure angle is the rear version of approach angle. It measures how steep of a drop the truck can leave without the rear bumper or body dragging.

For 2026, Ford lists 29.8 degrees for a Base 4-door, 36.9 degrees for a 4-door Sasquatch, and 40.5 degrees for the Raptor.

See our full departure angle guide for examples.

How Much Ground Clearance Does the Bronco Have?

Ground clearance is the distance between the ground and the lowest part of the vehicle.

For 2026, the Base measures 8.3 inches as a 2-door and 8.4 inches as a 4-door. Sasquatch reaches 11.6 inches on the 2-door and 11.5 inches on the 4-door. The Raptor reaches 13.1 inches.

What Does Crawl Ratio Mean?

Crawl ratio tells you how much the drivetrain reduces speed and multiplies torque in its lowest gearing. A higher number lets the truck move more slowly with finer control on steep or rocky terrain.

With the 7-speed manual, Ford lists a 79.92:1 crawl ratio with the standard transfer case and 94.75:1 with Advanced 4x4.

The 10-speed automatic is 57.19:1 with the standard transfer case and 67.80:1 with Advanced 4x4.

What Is the Difference Between 4-High and 4-Low?

4-High keeps a 1.00:1 transfer-case high range and is used when you need four-wheel drive without low-range gearing.

4-Low adds reduction in the transfer case. Ford lists a 2.72:1 low range for the standard transfer case and 3.06:1 for Advanced 4x4.

That reduction gives you slower wheel speed and more control for rocks, steep grades, deep ruts, and other low-speed terrain.

What Does a Locking Differential Do?

A locking differential lets both wheels on the same axle turn together instead of letting one wheel spin much faster than the other.

That can help when one tire has very little traction or lifts off the ground. Bronco configurations can use front and rear electronic locking differentials depending on trim and package.

Our locking differential guide explains when lockers help and when they do not.

What Does Sway Bar Disconnect Do?

The front stabilizer bar reduces body roll on the road, but it also ties the left and right suspension together.

Disconnecting it lets the front suspension move more independently over uneven terrain. Ford lists the disconnect as an available feature on certain configurations.

Our sway bar disconnect guide goes deeper into articulation.

What Are GOAT Modes?

GOAT stands for Goes Over Any Type of Terrain. These drive modes change vehicle settings for different surfaces and driving situations.

Depending on the configuration, a mode can change throttle response, transmission behavior, traction control, steering, and four-wheel-drive settings.

See our full GOAT Modes guide for the mode-by-mode breakdown.

What Does Trail Turn Assist Do?

Trail Turn Assist applies braking to the inside rear wheel during a tight low-speed turn. That helps the truck pivot more sharply on loose terrain.

Ford describes Trail Turn Assist as a feature for automatic-transmission Broncos. Availability still depends on the specific trim and equipment, so check the build sheet instead of assuming every automatic has it.

Our Trail Turn Assist guide explains how it works.

How Deep Can a Bronco Ford Water?

Water-fording depth is the maximum depth Ford publishes under its specified test conditions. It is not a safe target for every crossing.

For 2026, Ford lists 31.5 inches for standard configurations, 33.5 inches with Sasquatch, and 37.0 inches for the Raptor.

Ford also says to determine water depth before entering and to follow the owner's manual. Current, soft ground, hidden holes, and bow waves can make a crossing riskier than the depth number suggests.

What Does Payload Capacity Mean?

Payload is how much weight the vehicle can carry. Passengers, cargo, accessories, and added equipment all count against it.

Ford lists a maximum payload of 1,417 pounds for a 2026 4-door Base with the 2.3L and 7-speed manual. Other configurations are lower.

The door-jamb label is the number to use for a specific truck because options and equipment change available payload.

What Does GVWR Mean?

GVWR stands for Gross Vehicle Weight Rating. It is the maximum allowed weight of the fully loaded vehicle.

That includes the vehicle itself, passengers, cargo, fuel, and installed equipment. Ford's 2026 figures go up to 6,850 pounds on the Raptor.

A steel bumper, winch, armor, roof gear, and other heavy upgrades all use part of the payload before people and cargo are added.

What Are Rock Rails?

Rock rails protect the rocker area below the doors from contact with rocks and ledges.

Ford uses the term rock rails. The aftermarket often uses rock sliders for the same general type of protection, although construction and mounting strength vary by product.

See our rock rails guide for the full breakdown.
