The Superpro SPF3313XK is a precision-engineered rear upper inner control arm bushing kit. Featuring camber-adjustable geometry, this kit gives performance drivers and alignment technicians the ability to dial in rear suspension settings beyond factory specifications. Whether you're correcting camber drift on a lowered coupe or simply upgrading worn OEM rubber bushings, Superpro's polyurethane construction delivers a lasting improvement in handling, stability, and tire wear.

Key Features & Benefits

• Camber-Adjustable Design - Allows precise rear camber correction beyond OEM range, ideal for lowered vehicles or track-day setups where factory alignment specs fall short
• Superpro Polyurethane Construction - Engineered from proprietary polyurethane compounds that outperform OEM rubber in durability, load resistance, and long-term shape retention
• Reduced Bushing Deflection - Firmer bushing material minimizes unwanted suspension movement under load, translating to sharper steering response and improved corner entry/exit feel
• Greaseable Design - Includes grease ports or grease-compatible design for easy maintenance and elimination of squeaks over time
• Direct OEM Replacement Geometry - Engineered to fit the factory control arm location with no cutting, welding, or chassis modifications required
• Improved Tire Life - Correctable camber alignment reduces uneven inner or outer tire wear common on lowered or high-mileage
