S&B Body Mount Kit for 2001-2005 Chevy / GMC 1500, 2500, 3500 Extended / Crew Cab

S&B Filters 81-2001 Silicone Body Mount Kit

The S&B Filters 81-2001 Silicone Body Mount Kit is a direct replacement for the worn factory mounts on your 1999–2005 GM Silverado and Sierra (Extended & Crew Cab). These premium silicone mounts are designed to provide long-lasting performance and improved ride quality, backed by a lifetime warranty. Silicone construction resists ozone and heat damage, while corrosion-resistant steel cups and OEM-grade bolts ensure a secure and durable installation.

Made From Premium Silicone Rubber

These bushings provide superior vibration isolation and will not crack or break down like OEM foam or rubber mounts. The coated steel cups and bolts enhance corrosion resistance, ensuring long service life.

A Smooth Ride That Will Last a Lifetime

Stock body mounts degrade with time, and urethane alternatives can be too stiff and noisy. S&B’s silicone mounts maintain a smooth, factory-like ride and are designed to last the lifetime of your truck.

OEM Fit & Finish

The cap bushings feature a boss keyed to the frame tabs, ensuring precise OEM-style fitment and preventing rotation during installation.
