TRZ Motorsports Rear Upper Control Arms (G-Body) - 319-201
Rear Upper Control Arms for GM G-Body Platforms
The TRZ Motorsports Rear Upper Control Arms bring precision, strength, and adjustability to GM G-Body suspension setups. Designed for high-performance street, drag racing, and autocross applications, these upper arms allow you to adjust pinion angle without removing the control arms - a huge advantage during chassis tuning.
Constructed with a 1/4" thick formed steel clevis and double-gusseted reinforcement, these arms are built to handle serious power and aggressive launches. TRZ uses oversized premium chrome-moly rod ends with Teflon liners for maximum durability and smooth articulation.
The 4130 chrome-moly double adjusters and right-hand/left-hand threaded design provide fast, precise alignment and pinion angle adjustments. Lightweight 6061 aluminum bushings with 1/2" IDs help reduce unwanted deflection for improved traction and stability.
