You may have done it and just didn’t add it to your write-up, but if not, something that you also may want to do is remove the rear snubber extension brackets and mount the rubber snubbers directly to the frame rails to prevent early bottoming out. It will give you an extra 1.5/16” of clearance. Another item that can improve handling and ride somewhat is the installation of the front snubbers from an SS. This is an item you would just have to check out the part numbers for your particular truck, as while on the earlier 4WD’s, the parts were specific between the two, GM appears to later installed the SS style pieces on the regular 4WD’s as well. You can do a quick check without getting into looking up part numbers by just checking out the appearance of what you have installed on your truck. The SS pieces are just black rubber, while the older style 4WD pieces were a yellow-ish rubber. The stock SS Bump-Stop’s are part # 15161761 for both sides.

Here is a comparison shot between the two. Ignore the difference from one part being used.


You could also replace the factory jounce bumpers with Belltech 4923 bump-stop’s. They are a little shorter and softer than the factory pieces.

If you do find you want different pieces, Belltech has the part numbers below.
4922 – 1.26” tall x 2.5” O.D.
4923 – 2” tall x 2.5” O.D.
4924 – 3” tall x 2.5” O.D.
