There are our Chevy SS 13'-17' blot-on lift pads for the pinch welds. They come in a SET OF 4 and are made of billet aluminum and come in red and black. Easy to install and THESE WEIGH VERY LITTLE. They are angled to rock on the top of a floor jack and not bend the pinch weld. They are also angled to not catch on any road surface. They are great for use if you jack or lift your car allot and works with floor jack or lift. Comes with install wrench.
