Super Pro SPF2821K Front Upper Inner Control Arm Bushing Kit

The Super Pro SPF2821K is a high-performance polyurethane front upper inner control arm bushing kit designed to replace worn factory rubber bushings. Manufactured from premium polyurethane elastomer material, these bushings provide superior durability and performance compared to OEM rubber components while maintaining excellent ride quality.

Key Features:

• High-quality polyurethane construction for enhanced durability and longevity
• Maintains proper suspension geometry and wheel alignment under all driving conditions
• Application-specific durometer formulation balances performance with comfort
• Knurled surface design reduces friction and allows for unrestricted pivoting
• Self-lubricating properties extend bushing life and reduce maintenance
• Voiding technology allows polyurethane displacement under load to reduce NVH
• Prevents premature tire wear caused by worn rubber bushings
• Backed by SuperPro's lifetime warranty with no exclusions

Control arm bushings are critical components that stabilize suspension arm movement and maintain correct alignment geometry. When factory rubber bushings wear out, they allow excessive deflection that leads to dynamic alignment changes, poor handling response, and accelerated tire wear. SuperPro's polyurethane formulation solves these issues by providing long-lasting performance that holds alignment angles far longer than rubber, while their careful engineering minimizes the increased noise and harshness typically associated with polyurethane bushings.
