Product Description

The Prothane 7-148 Body Mount Kit is designed for 1999 through 2007 Chevrolet Silverado 1500 and GMC Sierra 1500 pickup trucks equipped with circular upper body mounts (commonly Canada models). This 16-piece kit uses round-style high-performance polyurethane bushings to replace worn rubber mounts, restoring ride height, improving cab-bed alignment, and reducing chassis flex, noise, and vibration.

Because these are direct-fit replacement bushings, installation is straightforward - just remove the old mounts and press in the new Prothane pieces with factory hardware. Available in either red or black (BL version), both offer identical durometer and performance; black includes graphite for reduced squeaks. Backed by Prothane's lifetime limited warranty and including Prop 65 compliance notice, this choice is ideal for owners with circular-style body mount designs seeking reliable, long-lasting chassis restoration.
