TRZ Motorsports Tubular Front Control Arms - Coilover Lowers Only (1977 - 1996 Impala / Caprice B-Body) - 322-CO-Lowers
Coilover-Specific Lower Control Arms for 1977 - 1996 Impala & Caprice
The TRZ Motorsports 322-CO-Lowers are high-strength tubular lower control arms designed specifically for coilover conversions on 1977 - 1996 Chevrolet Impala and Caprice B-Body vehicles. Constructed from TIG-welded chrome-moly tubing, these lowers provide superior rigidity, reduced weight, and improved suspension geometry for drag racing applications.
These coilover-only lowers accept all 1" wide à 1/2" ID bearing-style lower coilover shock mounts, allowing compatibility with most coilover systems. For QA1 shocks, TRZ recommends the COM8T-102PK bearing kit to ensure proper fitment. With 316-style geometry, these arms generally lower the front end by about 2 inches. Using 319/S10-style geometry, racers can achieve a more aggressive 2 - 3 inch drop depending on setup.
When used alongside TRZ's PRO Series upper control arms, the complete system supports 6 - 7 degrees of positive caster, dramatically improving high-speed straight-line stability. Uppers or lowers alone cannot achieve this caster range. The uppers also include travel limiters for precise front-end rise and weight-transfer tuning during hard launches.
Note: TRZ control arms are built for drag racing only. They do not include sway bar tabs and are not intended for street use.

Frequently Asked Questions
Can these coilover lowers be used with stock springs?
No. These lowers are coilover-only. For stock springs, use TRZ's 322-STK-Lowers.
Do these lowers alone provide the 6 - 7° caster improvement?
No. Achieving the full caster correction requires the complete TRZ upper + lower control arm system.
