Prothane 7-313-BL GM Full Size Rear Control Arm Polyurethane Bushing Kit - Black

The Prothane 7-313-BL is a rear control arm bushing kit engineered specifically for 1969–1970 GM full-size V-8 vehicles. Worn factory rubber bushings allow control arm deflection that directly disrupts caster and camber settings, leading to unpredictable handling, excessive tire wear, and a loss of steering precision. These polyurethane bushings are a direct, performance-oriented replacement designed to correct those issues at the source.

Prothane's proprietary polyurethane compound delivers significantly greater compliance resistance than OEM rubber, keeping the control arm geometry locked in place under load, during hard cornering, and at highway speeds. The result is crisper steering response, reduced suspension slop, and alignment settings that stay where you set them.

Key Features:

• Manufactured from high-durometer polyurethane for superior wear resistance over OEM rubber
• Resists petroleum, ozone, and UV degradation that deteriorate standard rubber bushings
• Engineered to maintain proper caster and camber alignment under all driving conditions
• Helps eliminate rear-end hop, wander, and high-speed steering vibration
• Black finish; sold as a complete rear control arm bushing kit
• Made in the USA
• Backed by Prothane's lifetime warranty

This kit is a straightforward upgrade for classic GM full-size platform restorers and performance enthusiasts looking to restore or improve rear suspension integrity on 1969–1970 V-8 applications.
