TRZ Motorsports Rear Upper Control Arms (1977 - 1996 Chevy Impala / Caprice - B-Body) - 322-201
Heavy-Duty Adjustable Upper Control Arms for 77 - 96 B-Body
The TRZ Motorsports Rear Upper Control Arms give your 1977 - 1996 Chevy Impala or Caprice (B-Body) a serious performance advantage with precision pinion angle adjustment, improved strength, and rock-solid rear suspension control. Built for drag racing setups running traditional 15" rear wheels, these arms are engineered to handle hard launches and aggressive power levels - not big-wheel racing.
Each control arm features a rugged 1/4" formed steel clevis with double gussets to prevent flex under load. Oversized chrome-moly rod ends with Teflon liners ensure smooth articulation, long service life, and dependable performance on high-horsepower builds. The RH/LH double-adjustable threads and 4130 chrome-moly adjusters allow you to fine-tune pinion angle without removing the arms - perfect for dialing in your launch geometry.
Paired with 6061 aluminum bushings (1/2" ID), these control arms provide a precise, bind-free connection that's far stronger and more consistent than the worn factory rubber bushings.

Frequently Asked Questions
Can these control arms be used on big-wheel or donk-style setups?
No. TRZ specifically designs these for drag racing with normal 15" wheel setups. They are not intended for big-wheel builds.
Do I need to remove the control arms to adjust pinion angle?
No. Thanks to the RH/LH double-adjustable design, pinion angle changes can be made on-car for quick tuning.
