70-87 GM 4wd Frt Spring Bushing Set Black

The Energy Suspension 70-87 GM 4WD Front Spring Bushing Set in black is a polyurethane leaf spring bushing kit engineered to restore suspension compliance and reduce drivetrain wear on fullsize GM trucks and SUVs. These Hyper-Flex bushings replace worn OEM rubber components with durable polyurethane-steel construction, addressing a critical wear point that affects steering response, ride quality, and drivetrain longevity in classic GM four-wheel-drive platforms from 1970 through 1987.

Polyurethane leaf spring bushings maintain their load-bearing properties and resilience far longer than rubber. As OEM rubber bushings deteriorate, they allow excessive frame deflection and bushing play—symptoms visible as clunking during acceleration, squat under load, and increased steering feel through the suspension geometry. The Energy Suspension front spring bushing set locks suspension articulation within tighter tolerances, reducing shock loads transmitted through the frame and drivetrain. The cadmium-plated steel backing plates prevent corrosion and ensure even load distribution across the suspension pickup points.

This kit is purpose-built for owners of 1970–1987 GM fullsize trucks and SUVs—Chevrolet and GMC platforms—who drive in variable terrain or regularly load their vehicles. Off-road users, those towing regularly, or drivers experiencing visible suspension wear will benefit from the improved bushing stiffness and durability. The black polyurethane color resists UV degradation and blends with OEM suspension architecture. Installation requires basic hand tools and suspension knowledge; the kit supplies all necessary bushings and fasteners for the front leaf spring assembly.

Energy Suspension is known for polyurethane suspension components that outlast rubber by several factors—particularly valuable on vehicles over 35 years old where OEM rubber has long since failed. This front spring bushing set represents a cost-effective entry point into modern suspension geometry without frame-off restoration, making it a standard upgrade for 4WD restoration and performance suspension work on classic GM platforms.
