TRZ Motorsports Rear Upper Control Arms (1968 - 1972 Chevelle - A-Body) - 317-201-2
Double-Adjustable Rear Upper Control Arms for 1968 - 1972 Chevelle
The TRZ Motorsports Rear Upper Control Arms are engineered for A-Body Chevelle owners who want stronger rear suspension geometry, improved traction, and quick pinion-angle adjustments without disassembling the arms. Designed specifically for the 1968 - 1972 Chevelle, these upper control arms provide the strength and precision needed for drag racing, street/strip setups, and high-power builds.
Each arm features a rugged 1/4" thick formed steel clevis that is double gusseted for maximum rigidity under hard launches. Oversized chrome-moly rod ends with Teflon liners deliver smooth movement and long-term durability. Thanks to the right-hand / left-hand double-adjustable threads and 4130 chrome-moly adjusters, pinion angle can be dialed in quickly and easily. The included 6061 aluminum bushings feature 1/2" IDs to work with standard 1/2" hardware.
