Restore the ride in your 1999-2005 GM Silverado/Sierra 1500/2500/3500 (Standard Cab) with the S&B Filters 81-2000 Silicone Body Mounts. These mounts are a direct replacement for your old and worn body mounts. S&B Filters designed these body mount kits out of premium silicone construction and they come backed with a lifetime warranty.
The mounts offer a great ride as compared to polyurethane mounts or worse, the old worn out originals. But, they’re pretty spendy. You do get what you pay for with these but almost $600 keeps me from giving five stars. I cannot speak on longevity but they do have a lifetime warranty so that’s a plus.
