High-Strength Double-Adjustable Rear Upper Control Arm for Precise Pinion Angle Control
The TRZ Motorsports 321D-201 Rear Upper Control Arm is engineered to give racers and performance enthusiasts an extremely strong, highly adjustable solution for dialing in rear suspension geometry. With on-car adjustability, you can fine-tune pinion angle without removing the arm - making trackside or garage adjustments fast and easy.
This control arm combines 4130 chrome-moly double adjusters, a 1/4? thick formed steel clevis, and dual premium chrome-moly rod ends with Teflon liners for maximum durability under heavy load. TRZ's design uses 6061 aluminum bushings with 1/2? IDs and a double-gusseted clevis for added rigidity, keeping suspension geometry locked in under hard launches. At neutral length, the arm measures 11.5? center to center.
