Vehicle Fitment

1967-1987 Chevrolet / GMC Full-Size Pickups & SUVs - various C/K-series trucks, Blazer, Suburban, Jimmy, etc., with 1.5" main eye / 1.5" frame shackle leaf springs (rear leaf spring application, 2WD/4WD depending on model and axle rating)

Features

High-durability Hyper-Flex™ polyurethane material - far longer service life than stock rubber bushings
Rear leaf spring & shackle bushing kit - replaces main eye and frame shackle bushings for rear leaf springs
Improved handling stability - reduced suspension flex and improved rear axle control under load, acceleration or braking
Enhanced ride quality and control over OEM rubber bushings, especially for heavy-duty use or trucks with loads/towing
Resists degradation from oils, road contaminants, and environmental exposure - more durable than rubber over long term
Polyurethane bushings help maintain bush alignment under stress - reducing wear and sagging over time
Direct-replacement design - meant to fit specified GM leaf-spring setups without modification
Pre-lubed or grease-compatible design (depending on version) for smoother operation and minimized bushing noise

Product Description

The Energy Suspension 3.2106G Rear Leaf Spring Bushing Kit offers a substantial upgrade over worn or deteriorated OEM rubber bushings for 1967-1987 GM full-size trucks and SUVs. By replacing the rear leaf spring main eye and frame shackle bushings with high-performance polyurethane, the kit significantly improves rear suspension stability, reduces unwanted axle movement, and enhances overall control, especially under load, towing, or heavy-duty use. Owners can expect firmer suspension behavior, improved handling, and more consistent alignment than with aging rubber components.

Because Hyper-Flex™ polyurethane resists oil, road salt, and environmental degradation, these bushings have a much longer service life and maintain their integrity over time - reducing maintenance frequency. The kit's direct-fit design allows for relatively straightforward installation on compatible GM leaf-spring rigs without frame modifications, replacing both main eye and shackle bushings as a set. For trucks used for hauling, towing, off-road, or daily driving, 3.2106G ensures the rear suspension behaves predictably and reduces the typical rubber-bushing flex and sag that accumulate over decades.

Upgrading to 3.2106G is especially beneficial for older GM pickups and SUVs with leaf-spring rear suspension that have seen many years of use. It restores suspension precision, improves load handling, and extends bushing life - making it a practical choice for restoration projects, heavy-duty work trucks, or vintage-vehicle owners seeking improved ride and handling without sacrificing comfort.
