First off... I installed them because my steering ram was smashing my oil pan jumping in tuff truck races (no more of that, to expensive) and just hard front suspension hits on the trail. Once i installed them the bumpstop had to be riding on the axle so it was low enough to stop steering ram to oil pan hits. out on the trail it was super annoying cause every bump the bumpstops would go... cluck..clunk..clunk..clunk..clunk..
Now with my steeing ram moved down lower and engine moved back my axle house more travel up and the mounts would have to redone. I think i will just put regular bumpstops back on with shock and put the air bumps on the shelf till I get the front 4link going some day:awesomework:
