it is difficult to encounter the slam stop on the street. speed bumps and normal elevation changes extend the suspension which results in a long travel for the spring and the shock to work on the terrain.

the problem encountered off road is such that the axle is 2-3 inches from the bumpstop during normal level travel and suddenly you hit a whoop, or a 5 inch ledge or crack in the dirt while traveling at say...25 mph and it slams and thuds audibly. it feels like the truck is going to break itself.

I can get it to slam coming down out of driveways onto flat pavement while turning slightly. this compresses one corner of the rear and you can sometimes slam it that way..on purpose..otherwise, it is hard to duplicate on the road since they are generally smooth.

I have a slightly modified timbren overload cushion/bumpstop solution on mine, but the best would be to add 1.5 to 2 inches of lift in combination with these bumpstops. I believe I will go ahead and try to get the calmini spacer/shackle setup this summer.

Nothing is perfect...this is the stupid part nissan passed off on us..it could be worse.
