Depending on where he decides to set the ride height - 72" roof height it'll have 8" up travel
In the front and 12" uptravel in the back. We will limit the down travel with limit straps just because you can get stupid amounts of travel with a trailing arm. Likely it'll be in the in the 20-24" range at final setup but we put adjustable limit straps on it for tuning . The front will use its full 16" of travel. When I first set out to build a bigger suspension travel rockwell rig I was really shooting for the 20" travel mark . We learned very quickly that 20" was easily attainable and actually could have way more then we could probably keep a drive shaft in and clear everything . Hopeing for a responsive fun , reliable trail rig that will bounce or dable with some jumping and higher speed under control.
