Every off-road spec sheet uses a set of terms that rarely get defined in plain language. This page collects them in one place: some link out to a full breakdown, and some are defined directly below with the numbers that matter for the Ford Bronco specifically.
In This Guide
Approach Angle
The steepest incline the front of the Bronco can climb before the bumper or lower fascia scrapes the ground. A base 4-door measures 35.5 degrees, Sasquatch-equipped models measure 43.2 degrees, and the Raptor tops the lineup at 47.2 degrees. Bumper choice can raise or lower this number from stock, which is worth knowing before buying a steel bumper for trail use. Read the full breakdown of approach angle.
Breakover Angle
The steepest crest the middle of the undercarriage can cross without the frame or skid plates dragging on the peak. This matters on rounded humps and crowned trails rather than straight climbs. A base 4-door Bronco measures 20.0 to 21.1 degrees, Sasquatch models measure roughly 26.3 to 29.0 degrees, and the Raptor measures 30.8 degrees.
Departure Angle
Approach angle's mirror image at the rear: the steepest decline the Bronco can drive down without the rear bumper or fascia dragging on the way out. A base 4-door measures 29.7 to 29.8 degrees, Sasquatch brings that to 37.0 to 37.2 degrees, and the Raptor leads at 40.5 degrees. Read the full breakdown of departure angle.
Crawl Ratio
The total gear reduction between the engine and the wheels in the lowest gear and low range combined. A higher number means finer, slower control at a crawl, which matters more on technical rock crawling than on graded trails. The manual-transmission Bronco with the standard transfer case reaches a 94.75:1 crawl ratio, a figure Ford marketed as best in its class at launch.
Ground Clearance
The distance from the ground to the lowest point of the vehicle's frame or undercarriage. A standard, non-Sasquatch Bronco sits at 8.3 inches. Adding the Sasquatch package's 35-inch tires and suspension raises that to 11.6 inches, which is the number most commonly quoted for the Bronco's off-road capability.
Water Fording Depth
The maximum water depth a vehicle can drive through on level ground without water reaching the engine's air intake or damaging electronics. A standard Bronco is rated for 31.5 inches, and Sasquatch-equipped models raise that to 33.5 inches. The Everglades trim, built with a raised air intake snorkel and raised axle, transfer case, and transmission vents, reaches 36.4 inches per Ford's own press specifications. These figures assume level ground; ruts and uneven streambeds reduce the safe margin in practice.
Locking Differential
A differential that can lock both wheels on an axle to spin at the same speed, instead of letting an open differential send all the power to whichever wheel has the least traction. This is what keeps a Bronco moving when one wheel lifts off the ground on uneven terrain. Read the full breakdown of locking differentials.
Sway Bar Disconnect
A system that electronically disconnects the front sway bar, allowing the front suspension to articulate independently instead of staying tied together. This lets the tires follow uneven terrain more closely, which improves traction on technical trails at the cost of body roll if used on pavement. Read the full breakdown of the sway bar disconnect.
GOAT Modes
Ford's name for the Bronco's drive mode system, short for Goes Over Any Terrain. Each mode adjusts throttle response, transmission behavior, traction control, and available four-wheel-drive settings for a specific condition, from Normal street driving to Rock Crawl. See the full breakdown of all 7 GOAT Modes.
4-Low vs. 4-High
Both are four-wheel-drive settings, but they change the gearing between the engine and the wheels. 4-High keeps a normal gear ratio and works for most on-road and light trail conditions at regular speeds. 4-Low adds a low-range gear reduction on top, multiplying torque at the wheels for slow, technical situations like steep climbs, deep mud, or rock crawling, at the cost of a much lower top speed.
Trail Turn Assist
A feature that brakes the inside rear wheel during a tight, low-speed turn in 4-Low, which lets the Bronco pivot around that wheel and turn in a noticeably tighter radius than the same truck without it engaged. Read the full breakdown of Trail Turn Assist.
Payload Capacity
The maximum combined weight of passengers, cargo, and any added equipment the vehicle can carry, separate from towing capacity. Bronco payload ranges from roughly 1,000 to 1,300 pounds depending on trim, doors, and options, since heavier packages like Sasquatch reduce the payload figure even as they add off-road capability elsewhere.
GVWR
Gross Vehicle Weight Rating: the maximum total weight the vehicle is rated to carry, including the truck itself, passengers, cargo, and fuel. Bronco GVWR ranges from 5,540 pounds on a lighter 2-door trim up to 6,160 pounds on a loaded 4-door Wildtrak. This number determines which weight class rules apply to a specific Bronco, including some California exhaust noise limits covered in our California laws guide.
Rock Rails
Ford's factory name for tubular or plated bars mounted along the rocker panel, positioned to absorb a direct hit against a rock or ledge instead of letting it strike the body. The aftermarket generally calls the same category rock sliders. Read the full breakdown of rock rails.
Pinch Weld Covers
Covers for the pinch weld, the seam where the floor pan and rocker panel are welded together along the bottom edge of the doors. Left exposed, this seam is a common point of paint chipping and corrosion once the doors are removed and reinstalled repeatedly. Read the full breakdown of pinch weld covers.
FAQ
What's the difference between approach angle and breakover angle?
Approach angle covers the front of the vehicle climbing an incline. Breakover angle covers the middle of the undercarriage crossing the crest of a hump or crowned trail without dragging.
How deep of water can a Ford Bronco drive through?
31.5 inches on a standard Bronco, 33.5 inches with Sasquatch, and 36.4 inches on the Everglades trim's snorkel and raised-vent system. These figures assume level ground.
What's the Ford Bronco's crawl ratio?
94.75:1 on a manual-transmission Bronco with the standard transfer case, a figure Ford marketed as best in its class when the truck launched.
Do I need 4-Low for most trails?
No. 4-High handles most on-road and light trail conditions at regular speeds. 4-Low is for slow, technical situations like steep climbs, deep mud, or rock crawling, where the extra gear reduction adds torque at the wheels.
Why does GVWR matter for a Bronco build?
It determines which weight class rules apply to a specific Bronco, including some state-level exhaust noise limits, and it caps how much added weight (bumpers, a winch, roof rack cargo) the truck can carry before exceeding its rating.
