Departure angle shows up right next to approach angle on every Bronco spec sheet. It covers a different kind of scrape, one at the back of the truck instead of the front. Here's what it measures, why it matters, and how it compares across the Bronco lineup.

What Is Departure Angle?
Departure angle is the steepest decline a vehicle can drive down without its rear bumper scraping the ground on the way out. It's measured from level ground up to a line drawn between the rear tire's contact patch and the lowest hanging point at the rear of the vehicle. A higher number means the rear end clears a steeper drop-off before anything hangs up.
Picture backing down off a rock ledge or driving off the lip of a steep descent. If the departure angle is too shallow, the rear bumper or hitch drags on the ledge before the rear tires clear it. A steeper departure angle lets the vehicle roll off the obstacle without the tail end catching.
Why Is Departure Angle Important?
Departure angle matters most on the way down. Think ledges, steep exits, and drop-offs. The front tires have already cleared, but the rear end is still coming through. It's a smaller concern on graded trails and dirt roads, since the ground rarely drops off that sharply.
It's also a direct, factual reason owners replace a factory rear bumper. A stock rear bumper hangs lower and extends farther back than most aftermarket options. That's why departure-angle complaints on stock Broncos often go away once a tube or high-clearance rear bumper goes on.
Departure Angle by Bronco Trim
A base 4-door Bronco without Sasquatch measures 29.7 to 29.8 degrees of departure angle. Adding the Sasquatch Package and its 35-inch tires brings that up to 37.0 to 37.2 degrees. The Raptor tops the lineup at 40.5 degrees, the highest departure angle Ford builds into any Bronco trim without aftermarket modification.
Approach and Breakover Angle, Briefly
Departure angle is one of three related off-road angles. The other two cover different parts of the vehicle. Approach angle measures the steepest incline the front end can climb without the front bumper scraping first. Breakover angle measures the steepest crest the undercarriage can cross without dragging in the middle, relevant on rounded humps and crowned trails.
On a base 4-door Bronco, approach runs 35.5 degrees and breakover runs 20.0 to 21.1 degrees. Sasquatch brings those up to 43.2 degrees approach and roughly 26.3 to 29.0 degrees breakover. The Raptor leads all three categories at 47.2 degrees approach, 30.8 degrees breakover, and 40.5 degrees departure.
How Rear Bumper Choice Changes Departure Angle
Not every aftermarket rear bumper improves departure angle over the factory setup. A full-width rear bumper can lower departure angle if it has a low-hanging tire carrier or fuel can mount. Tube-style and high-clearance rear bumpers almost always improve it instead. Check the specific bumper's published spec rather than assuming any steel rear bumper helps. We cover what to look for in our full Ford Bronco rear bumper guide.
FAQ
What's the departure angle of a stock Ford Bronco?
A base 4-door Bronco without Sasquatch measures 29.7 to 29.8 degrees. Sasquatch-equipped models measure 37.0 to 37.2 degrees, and the Raptor tops the lineup at 40.5 degrees.
Does a bigger rear bumper always improve departure angle?
No. A low-hanging tire carrier or fuel can mount can bring departure angle down. Tube-style and high-clearance designs almost always improve it instead, but check the product's published spec first.
What's the difference between departure angle and approach angle?
Departure angle covers the rear of the vehicle clearing a decline on the way down. Approach angle covers the front of the vehicle climbing up an incline.
Which Bronco trim has the best departure angle?
The Raptor, at 40.5 degrees, the highest departure angle in the Bronco lineup without any aftermarket modification.
