How to measure your truck
- Park on level ground at your normal load, with tires at your usual pressure.
- Wheelbase: measure from the center of the front hub to the center of the rear hub.
- Clearance at mid-wheelbase: find the lowest point between the axles, such as a skid plate, exhaust or frame crossmember, and measure to the ground.
- Front overhang and height: measure horizontally from the front hub center to the lowest front corner (bumper, air dam or skid), then measure that corner's height.
- Rear overhang and height: do the same at the back, using the lowest point, which is often the hitch receiver or exhaust tip.
The calculator finds the line from each low point that just touches the tire, which is how angles are defined, and it accounts for tire size. For breakover it uses the midpoint between the axles.
Cheap departure-angle upgrade
Pull the receiver-hitch ball mount before hitting the trail. On many trucks it's the lowest point at the back, and removing it can add several degrees of departure angle.
