TRZ Motorsports Pro Upper and Lower Control Arms for Stock Springs (1963 - 1982 Corvette C2 / C3) - 320-PRO-STK
High-Performance TRZ Pro Control Arms for 1963 - 1982 Corvette (C2 & C3)
The TRZ Motorsports Pro Upper and Lower Control Arm Kit is engineered for Corvette owners looking to shed weight, improve geometry, and upgrade to motorsports-grade front suspension performance. Designed specifically for all 1963 - 1982 Corvette C2 and C3 models running factory-style springs, this setup replaces the OEM arms with precision TIG-welded chrome-moly construction for unmatched strength and lighter weight.
This complete kit includes upper and lower control arms, ball joints, bushings on the lowers, rod-end uppers, and all required mounting hardware. TRZ builds in 6° positive caster to help stabilize high-speed drag cars and deliver improved straight-line tracking. The uppers also feature built-in travel limiters to control suspension rise during launches.
These control arms bolt directly into place with no chassis modifications required and support either the OEM spring/shock combo or a bolt-in t-bar coilover system from QA1, Viking, or AFCO. TRZ also notes they can configure this kit to work with TRZ spindles or factory A/F/X-body drum or disc spindles upon request.
