Chevy ZQ8 Bump Stop Mod


Recommended Posts

I just made a really nice simple and cheap mod to my 411. My car is lowered about 2" in the front and the stock (old, hard) rubber bump stops were about 3/4" away from the frame and would bottom out pretty often. I bought a pair of Chevy S10 ZQ8 type bump stops (Dorman #31064, http://www.summitracing.com/parts/RNB-31064 ) as replacements and they are AWESOME. The ride is so much better now.

 

These bump stops are made of pretty soft delrin and are designed to compress progressively. In lowered S10s they will touch the frame at rest.

 

The mounting stud on the bushing is too short so I hammered it out and replaced it with a 2" 9/16 carriage bolt. This will fit in the existing hole in the lower a-arm. I added 4 washers to shim the bushing higher and closer to the frame, so I have it about 3/4" from the frame at rest. This is the same distance as the old bump stop, but since this bushing is much softer and compresses progressively it actually increases the amount of suspension travel but still cushions it fine.

 

The bump stops are aout $10 each. I had the 2 bolts and 8 washers laying around, but those probably cost less than $2 total.
