Rear Leaf Sping Bushings

Rear leaf spring bushings are critical suspension components that connect your vehicle's leaf springs to the frame, absorbing road shock and controlling articulation during acceleration, braking, and cornering. The Rear Leaf Spring Bushings in this kit replace worn factory rubber or original equipment on GM fullsize SUVs from 2000–2003, restoring suspension geometry and eliminating the clunking, wandering handling that degrades safety and ride quality. Whether you're towing, hauling payload, or simply want a tighter, more predictable suspension, upgrading to quality rear leaf spring bushings is one of the highest-return suspension modifications available.

This kit features Hyper-Flex polyurethane construction bonded to steel sleeves, a material pairing that outperforms factory rubber in durability, load capacity, and vibration isolation. Polyurethane bushings resist cracking, oil degradation, and UV exposure far longer than rubber, while the embedded steel core prevents excessive deflection under heavy suspension loads. The cadmium-plated steel hardware resists corrosion in wet climates and salt exposure, critical for long-term reliability in rear suspension applications where mud and moisture accumulate. At 5.35 lbs, this complete kit includes all bushings and fasteners needed for full rear suspension refresh on compatible GM fullsize SUV platforms.

Mechanics and serious DIY builders favor polyurethane bushings for lifted trucks, towing packages, and vehicles that see heavy-duty use, because they maintain suspension alignment and response far better than aged rubber throughout the lifespan of the vehicle. Installation requires basic hand tools and suspension jack safety precautions; rear leaf spring bushing replacement typically takes 2–4 hours per side depending on bolt corrosion and access. This kit is engineered specifically for GM fullsize SUVs (2000–2003 model years), ensuring proper fitment, geometry, and load rating for your platform's suspension demands.
