SuperPro SPF4517K Upper Control Arm Polyurethane Bushing Kit

The SuperPro SPF4517K is an upper control arm bushing kit engineered to restore and improve your vehicle's suspension geometry. Manufactured from SuperPro's proprietary polyurethane compound, these bushings are a direct upgrade over worn or degraded OEM rubber bushings that can cause unpredictable handling and accelerated tire wear.

Why Replace Your Control Arm Bushings?

Control arm bushings stabilize the movement of the suspension arms to ensure correct wheel geometry is maintained under all driving conditions. Worn rubber bushings allow dynamic changes in wheel alignment that negatively affect handling precision and tire longevity. The SuperPro SPF4517K eliminates this problem with a durable polyurethane solution built to last.

Key Features:

• Manufactured from SuperPro's proprietary polyurethane blend — significantly more durable than OEM rubber
• Maintains correct suspension geometry and steering alignment angles
• Reduces unwanted suspension flex, improving handling response and vehicle stability
• Application-specific durometer (bushing hardness) balances performance with ride comfort
• Engineered and developed in Australia, tested in some of the world's harshest conditions
• Backed by SuperPro's Limited Lifetime Warranty, including coverage for racing and off-road use
• Includes lubricant for installation; warranty covers against squeaking when lube is properly applied
