Product Description

The Energy Suspension 3.2106R rear leaf spring bushing kit is designed to upgrade the rear suspension of classic 1967-1987 Chevrolet and GMC full-size trucks and SUVs that use a 1.5" main-eye / 1.5" frame-shackle leaf spring setup. By replacing worn rubber bushings with durable Hyper-Flex™ polyurethane, this kit significantly improves rear axle stability, reduces unwanted movement and flex, and enhances handling - especially under load, towing, or during sharp acceleration or braking.

Thanks to polyurethane's superior resistance to wear, oil, road salt and environmental exposure, these bushings outlast standard rubber by a wide margin, reducing the need for frequent maintenance or replacement. The kit's direct-fit design ensures easy installation with no modifications needed (provided your leaf spring eye and shackle dimensions match), making it an excellent choice for restoration projects, heavy-duty work trucks, off-road builds, or vintage vehicle owners seeking improved longevity and suspension control.

Whether you're hauling heavy loads, navigating rough roads, or seeking a more controlled and stable ride - 3.2106R offers a substantial improvement over aging or deteriorated original leaf-spring bushings. It delivers firmer suspension behavior, improved load handling, and extended service life, making it a cost-effective upgrade for classic GM trucks and SUVs.
