Super Pro SPF0753K Leaf Spring Shackle Bushing Kit Polyurethane Replacement

The Super Pro SPF0753K is a complete polyurethane leaf spring shackle bushing kit designed to replace worn or degraded OEM rubber bushings in the rear suspension. Leaf spring shackle bushings are critical to rear axle stability — when they wear out, the rear axle can shift under load, resulting in unpredictable handling, wandering, and instability under braking, particularly when towing or carrying heavy cargo.

Super Pro's bushings are manufactured from a proprietary engineering-grade polyurethane formulation — not a copy of the OEM rubber design — purpose-built to take advantage of the unique performance properties of polyurethane while minimizing noise, vibration, and harshness (NVH). The result is a bushing that delivers improved rear-end control and reduced deflection compared to stock rubber, without sacrificing ride quality.

Key Features:

• Engineered polyurethane construction outlasts OEM rubber bushings
• Reduces unwanted rear axle movement and passive rear steer
• Improved stability under load, towing, and heavy braking conditions
• Internal geometry designed to retain grease for long-term, low-maintenance performance
• Includes all necessary bushings for a complete shackle bushing replacement
• Backed by Super Pro's lifetime warranty
• Manufactured in Australia to strict engineering and quality standards

The SPF0753K kit is a straightforward drop-in upgrade for vehicles with leaf spring rear suspension, restoring precision and confidence to the rear end of trucks, SUVs, and 4WD platforms whether on pavement or off-road.
