Prothane 69-87 Chevrolet Pickup 4WD Spring Bushing Kit (Replacement for SuperLift 315)

If you're working on the suspension of your classic Chevrolet or GMC pickup, especially a 4WD model from 1969 through 1987, this Prothane spring bushing kit is what you need. This kit is designed to replace the stock or worn-out bushings in your leaf springs and shackles, which are crucial for absorbing road shock and maintaining proper alignment. Worn bushings can lead to a rougher ride, clunking noises, and uneven tire wear, so replacing them with a well-built set like these can make a notable difference in how your truck handles.

Prothane uses a durable polyurethane material for these bushings, which offers a good balance of flexibility and resilience. Polyurethane is known for its resistance to abrasion, chemicals, and extreme temperatures, meaning these bushings should hold up well over time, even under the demands of truck use. This particular kit is a direct replacement for the SuperLift 315 part number, making it a straightforward choice if you're familiar with that setup or are looking to upgrade from an existing lift kit component. The material is designed to provide a firmer feel than rubber, which can improve steering response and reduce body roll without making the ride overly harsh.

This kit is intended for a range of Chevrolet and GMC K-series trucks, including models like the K10, K20, K5 Blazer, and corresponding GMC Jimmy and Sierra variants. Ensure you check the full fitment guide to confirm compatibility with your specific year and model. Replacing suspension bushings is a common task when restoring or rebuilding older trucks, and having a reliable kit like this from Prothane can help ensure your suspension performs as it should.
