SSThunder Posted March 31, 2009 Report Share Posted March 31, 2009 Thanks for the info Tzer tzer how much did you trim off the bump stops ??? I'm pretty sure you just remove 1 nub off the rear bump stops and mount them to the frame instead of the mounting plate. For the front bump stops, you just drill them. MrP has a how-to on this I think so search for that. Quote Link to comment Share on other sites More sharing options...
ss wrecker Posted March 31, 2009 Report Share Posted March 31, 2009 i just removed the bumpstop mounting bracket and mounted it to the frame no nub cutting. 2" spindles and shackles on mine Quote Link to comment Share on other sites More sharing options...
budhayes3 Posted March 31, 2009 Report Share Posted March 31, 2009 Granted I'm not an SS, but my suspension is very similar to you SS guys, just a little shorter lol. I dropped my rear by installing 2" shackles and removing the 4x4 lift blocks, and I didn't need any shims...my drop actually cured a vibration I had lol. I dropped the front with Belltech keys and cut about 1 nub off the front bump stop. You want the front bump stops just touching the lower control arms, not completely off of the control arms and not compressed against the control arms. The bump stops are actually factored in to the spring rate of the front end and aid in the feel of the ride. When I first dropped my truck, I cut the bump stops too short, and the front end was wishy washy. Then I bought a new set of rubber bump stops (the factory Z71 bump stops were made of a much harder material), and cut them until they just touched the lower control arm and the front end now feels responsive...aside from the bumpsteer that I experience which is much worse when I have my summer 20's on, but not so bad with my winter 16's.

I have that nut and washer in my center console and has a part # 2508-777 on the plastic package Quote Link to comment Share on other sites More sharing options...

I can understand the not having a place to do it, but it really is self explanatory once you dig into it. The shackles are retarded easy. I tackled mine having slim to none knowledge on suspension, couldnt even point out a torsion bar to anyone at that time if I tried . Only thing I messed up was cuttin the bumpstops a little short Quote Link to comment Share on other sites More sharing options...
js_silveradoSS Posted May 6, 2009 Report Share Posted May 6, 2009 I have a vibration starting at about 75/80 mph and i feel it on hard acceleration all the way from 0. its smooth at crusing speeds. It wasn't their before i did the belltech drop kit. Got the 2 degree shim and it changed to 80/85 and still on hard accel. I moved the pinion downward. I do drag the truck and i am often @ or above 85. not sure what to do. do i need more shim degree? Any ideas? Quote Link to comment Share on other sites More sharing options...
