TRZ Motorsports Pro Upper and Lower Control Arms for Coil-Overs (1963 - 1982 Corvette C2 / C3) - 320-PRO-CO
High-Performance Coil-Over Control Arms for C2 & C3 Corvette
Upgrade your 1963 - 1982 Corvette (C2/C3) front suspension with the TRZ Motorsports PRO Series Upper and Lower Control Arms, engineered specifically for coil-over shock setups. Built from lightweight, tig-welded chrome-moly tubing, this complete control arm package delivers major gains in strength, geometry, and weight reduction for drag-oriented builds.
Designed as a direct replacement for factory arms with no chassis modifications required, these arms add built-in caster, reduce front ride height, improve suspension travel control, and significantly cut weight - up to 15 lbs per side. The PRO upper arms also include integrated travel limiters for repeatable launches and improved weight transfer.
This system is compatible with all common coil-over shocks except the QA1 Pro-Coil System (unless converted to bearing COM8T-102PK). TRZ can also build these arms for use with TRZ spindles or A/F/X-body spindles upon request.
