Features

• Aluminum hex center section allows simple on-car pinion angle adjustment - just loosen the jam nuts and rotate to dial in the desired setting without removing the arms from the vehicle
• Spherical ball / rod end assembly on the chassis end eliminates bushing bind, allowing the rear suspension to move freely for better control and more predictable handling
• Replaces soft OE rubber differential bushings with high-quality polyurethane bushings for improved axle location and stability under hard acceleration
• UHMW polyethylene bushings at the chassis end reduce friction for smoother suspension travel
• Red anodized aluminum finish on the hex adjuster body for corrosion resistance and a high-quality underbody appearance
• 1-1/4 in. diameter, 0.120 in. wall steel tubing construction for high strength with reduced weight versus OEM-style boxed arms
