SuperPro SPF5612K Rear Leaf Spring Shackle Bushing Kit

The SuperPro SPF5612K is a rear leaf spring and shackle bushing kit engineered from SuperPro's proprietary polyurethane formula to restore and improve rear suspension performance. Designed as a direct replacement for worn or deteriorated OEM rubber bushings, this kit addresses a commonly overlooked source of rear-end instability, axle wander, and unwanted noise.

Key Features:

• Manufactured from SuperPro's engineering-grade polyurethane — a special elastomer that combines the best characteristics of rubber and rigid plastic
• Resists wear, heat, and deformation for a significantly longer service life than factory rubber bushings
• Reduces unwanted rear axle movement and passive rear steer for improved stability and steering feel
• Maintains consistent suspension geometry under load, braking, and cornering conditions
• Engineered to minimize NVH (noise, vibration, and harshness) — SuperPro's proprietary blend and internal geometry retain grease to prevent squeaking
• Backed by SuperPro's lifetime warranty, including racing and off-road applications
• Complete kit includes all necessary bushings for both spring eye and shackle positions

Worn leaf spring and shackle bushings allow the rear axle to shift during acceleration, braking, and cornering, causing the vehicle to wander — a problem especially noticeable when towing or carrying heavy loads. The SuperPro SPF5612K restores proper axle location and delivers the consistent rear-end control needed for confident daily driving and demanding use alike. Manufactured in Australia under strict quality control standards.
