UMI Performance 401517-R Rear Upper Control Arms for GM A-Body

The UMI Performance 401517-R rear upper control arms are precision-engineered tubular control arms designed for GM A-Body vehicles including the 1964-1972 Chevelle, El Camino, GTO, Cutlass, and Skylark. These high-performance control arms replace the factory stamped steel arms with heavy-duty tubular steel construction for improved strength, reduced weight, and enhanced suspension geometry.

Key Features:

• CNC-bent 1-inch diameter DOM steel tubing for maximum strength and minimal weight
• TIG-welded construction ensures durability under extreme conditions
• Greasable polyurethane bushings provide long-lasting performance and easy maintenance
• Adjustable design allows for precise rear axle alignment and pinion angle correction
• Red powder-coated finish for corrosion resistance and a clean appearance
• Direct bolt-in installation with no modifications required
• Sold as a pair (left and right sides included)

These control arms are ideal for street performance, drag racing, and autocross applications where improved rear suspension control and adjustability are essential. The adjustable length design allows you to correct rear axle alignment issues and optimize pinion angle for reduced drivetrain vibration and improved power transfer.
