TRZ Motorsports Tubular Front Control Arms - Stock Spring Style Complete Kit (1977 - 1996 Impala / Caprice B-Body) - 322-PRO-STK
Complete Stock-Spring Front Control Arm Kit for 1977 - 1996 Impala & Caprice
The TRZ Motorsports 322-PRO-STK kit is a full front control arm system engineered for 1977 - 1996 Chevrolet Impala and Caprice B-Body platforms. Built from premium TIG-welded chrome-moly tubing, this kit replaces the heavy factory arms while dramatically improving strength, weight reduction, and suspension geometry for serious drag racing performance.
This complete kit includes PRO Series upper control arms with chrome-moly rod ends and billet cross-shafts, along with stock-spring lower control arms designed to accept OEM-style springs and shocks. The lowers feature dropped spring perches to accommodate taller aftermarket springs, and depending on spring selection, the front ride height may naturally drop between 1.5 and 1.75 inches.
When used together, the upper and lower arms allow the suspension to achieve 6 - 7 degrees of positive caster, providing outstanding straight-line stability and improved launch consistency. The uppers also include travel limiters to fine-tune front-end rise and weight transfer.
Note: TRZ A-arms are built exclusively for drag racing use. They do not include sway bar tabs and are not intended for street applications.

Frequently Asked Questions
Does this kit work with coilovers?
No. This is a stock-spring-only complete kit. For coilovers, use the 322-PRO-CO version.
Will I get the full 6 - 7° caster increase with just the uppers?
No. Achieving the intended caster range requires the complete upper and lower arm system installed together.
