Rear Tracking Arm Bushings Black

The Rear Tracking Arm Bushings Black by Energy Suspension are engineered replacements for worn or compromised factory bushings in GM fullsize trucks from 1961–1972. These polyurethane and steel composite bushings mount to the rear Panhard bar (lateral tracking arm), a critical component that controls side-to-side axle movement and lateral chassis compliance. Mechanics and enthusiasts choose aftermarket bushings when original rubber components deteriorate, leading to increased play in the suspension geometry, reduced handling precision, and accelerated wear on other suspension components.

Energy Suspension's Hyper-Flex polyurethane formulation is significantly more durable than factory rubber, resisting age-related hardening, UV exposure, and oil degradation that plague original components over decades of use. The black polyurethane is bonded to steel inner and outer sleeves, creating a bushing that maintains its elasticity while providing predictable resistance to deflection under cornering loads and suspension articulation. This design reduces vagueness in the rear axle's lateral location, which directly improves steering response and reduces body roll during aggressive driving or towing operations—critical qualities for vintage truck owners who modify their vehicles for performance or weekend use.

Restoration shops, weekend fabricators, and vintage truck builders benefit most from this kit, as original rubber bushings on 1961–1972 GM fullsize pickups and Suburban models are nearly impossible to source without compromise. Installation requires basic suspension tools and lifting equipment; the bushings press into the Panhard bar's mounting points and anchor to the chassis or axle housing depending on the truck's specific suspension configuration. For trucks showing signs of loose rear-end movement, steering wandering at highway speeds, or visible separation between the tracking arm and its mounting points, replacing these bushings restores baseline suspension control and extends the service life of related components like tires, shocks, and driveline parts.
