Vehicle (stock) Departure Angle
Departure angle is the steepest slope you can back down or drive off without the rear bumper, hitch, or tow point dragging. It is governed by how far the lowest rear point extends behind the rear tire and how high it sits. A trailer hitch is often the lowest rear point and the first thing to catch on a ledge.

What Departure Angle Tells You

Departure angle is the maximum slope you can descend or back off before the rear of the vehicle drags. It is the mirror image of approach angle and matters every time you crest a ledge and the back end has to follow the front down. A bigger number means cleaner exits off steep obstacles.

The Hitch Problem

On most trucks and SUVs the receiver hitch hangs lower and farther back than the bumper, making it the true limiting point. Removing the drawbar or fitting a high-clearance rear bumper often recovers several degrees and is one of the cheapest off-road upgrades.

Improving Departure Angle

Larger tires and a lift raise the rear, while shortening rear overhang and tucking the bumper and exhaust help most. Long-overhang vehicles such as extended-cab long-bed trucks are inherently limited here, which is why short-wheelbase rigs shine on technical terrain.

Frequently Asked Questions

What is a good departure angle?

Stock trucks land around 20 to 25 degrees; dedicated trail rigs reach the high 30s to low 40s. Under 20 degrees you will catch the rear on steeper ledges.

Does a spare tire carrier hurt it?

A swing-out or hitch-mounted carrier can, if it hangs low. Bumper-integrated carriers are usually tucked to preserve the angle.

Why is mine worse than approach?

Many vehicles have longer rear overhang and a low hitch, so departure is commonly the smaller of the two angles.
