When I drop the truck fram about 4-5 feet the rear end does not touch and the truck doesn't bounce. I actually thought the shocks handled it very smoothly but on the track that is not the case.

I have the jet vent pistons with tapered ends up meaning they would move faster on impact as opposed to rebound. I am going to put in some heavier oil. Would it make sense to stiffen the rear to prevent the rear flipping??
