My 4x4 Toyota truck needs something extra in the front to help with bottoming out. I have a 2 tube bypass on the front now. The front cycles out at about 13.5" travel. Problem is it's only a 8" travel shock and mounted about 1/2 way in on the lower arm, so the shock's shaft speed is so low that the bypass tubes have to be almost completely closed even with double-stacked .020" shims! I want something more to help out with the last 6" or so of compression travel. I was thinking about a 12" or 14" airshock mounted way out on the lower arm but I was told they will heat up quickly on the front of a truck. Airbumps would work but it is a 4x4 and I am running out of room to fit them. Does anyone make a airbump that looks/mounts like a shock? Any other suggestions?
