The short answer
Walk the obstacle, then choose a line that keeps the tires on the high points and the middle of the car clear. Go slowly in 4L with a spotter. Place each wheel deliberately, and ease a wheel off a ledge slowly with light brake or Hill Descent Control. The underbody and the diff housings are your weak spots.
Do
- Walk the line first
- Use a spotter
- Stay in 4L at a crawl
- Aim tires at high points
- Ease down ledges slowly
Do not
- Rush it
- Drive over the middle of a rock
- Drop off a ledge
- Spin the wheels on rock
- Ignore the underbody
Read the line
- Look for the highest, flattest spots for the tires, not the biggest gap
- Check where the diffs and the middle will pass, since breakover is only 24 degrees
- Look for sharp edges that can cut a sidewall
- Plan the exit as well as the entry
- If it needs a lot of rock stacking, consider another way
Wheel placement
- Place the front wheel on top of the rock, then the rear follows
- Use small steering movements, since the wheel can slip off
- Pick one wheel at a time to climb, the others stay down
- Keep the speed at a crawl and the throttle steady
Easing a wheel off a ledge
- Stop square to the ledge and check with the spotter
- Let the wheel roll over slowly, with the brake or Hill Descent Control holding speed. See Hill Descent Control
- Keep the other wheels steady and avoid a drop that slams the front
- If the drop is too big, build it up with rocks or choose another line
Protect the car
Skid plates and sliders help, see underbody protection. Tire pressures matter too, see tire pressures. For a stuck wheel, see cross-axle flex and wheel lift.

Common mistakes
- Driving over the middle. Breakover is 24 degrees.
- Rushing the ledge. It slams the front.
- Skipping the spotter. You cannot see the wheels.
- Spinning on rock. It damages tires.
- Ignoring the exit. Plan both ends.
