Product Description

The Energy Suspension 3.4140G Body/Cab Mount Bushings are engineered as a direct replacement for aging and worn rubber body and cab mounts on 1970-1980 Chevrolet and GMC C/K series Crew Cab pickups. Molded from Hyper-Flex™ polyurethane, this kit combines cushioning comfort with rugged durability, helping maintain proper cab-to-frame and body-to-bed alignment far longer than soft OEM rubber. Its robust design resists distortion, cracking, and environmental degradation for improved longevity and ride quality.

Ideal for restoration projects, suspension refreshes, or daily use on classic GM Crew Cab trucks, these bushings help restore original ride height and reduce excessive body movement under load. The set covers all necessary mounting points and delivers a balance of smooth ride comfort and structural stability without affecting regulated emissions systems. Professional installation is recommended to ensure correct alignment and fitment.
