Super Pro SPF5789K Rear Leaf Spring Shackle Bushing Kit

The Super Pro SPF5789K Rear Leaf Spring Shackle Bushing Kit is a high-performance polyurethane upgrade designed to restore handling, stability, and ride quality in your truck. This replacement bushing kit addresses worn or damaged factory rubber bushings that connect the rear axle to the vehicle frame at the shackle point.

Key Features:

• Manufactured from Super Pro's proprietary polyurethane formula for superior durability and longevity compared to factory rubber
• Eliminates rear axle movement that causes wandering, wobbling, and passive rear steer
• Reduces deflection under load for improved stability during heavy towing and hauling
• Minimizes road wander and instability during heavy braking
• Decreases noise, vibration, and harshness from worn suspension components
• Engineered to handle extreme loads, oversized tires, and harsh operating conditions

Leaf spring bushings are critical but often overlooked suspension components that stabilize rear axle movement. When factory rubber bushings deteriorate, they allow excessive axle movement that becomes especially noticeable when carrying heavy loads or towing trailers, boats, or RVs. Super Pro's polyurethane construction provides decreased deflection, increased durability, and extended service life to keep your truck stable and responsive under demanding conditions.
