TRZ Motorsports Tubular Front Control Arms - Uppers Only (1964 - 1972 Chevelle A-Body) - 317-PRO-Uppers
High-Strength Tubular Upper Control Arms for 1964 - 1972 Chevelle A-Body
The TRZ Motorsports Tubular Front Control Arms - Uppers Only (317-PRO-Uppers) are engineered for drag racers who demand maximum strength, caster stability, and front-end weight transfer on 1964 - 1972 GM A-Body Chevelle platforms. Constructed from TIG-welded chrome-moly tubing, these upper arms deliver exceptional rigidity while reducing front-end weight compared to stock stamped-steel arms.
All TRZ upper control arms in this series feature chrome-moly rod-ends attached to billet cross-shafts for ultra-precise alignment control. These arms are designed exclusively for performance use and include built-in travel limiters to fine-tune upward travel and improve weight transfer during launch. TRZ builds aggressive caster directly into the geometry, providing 6 - 7 degrees of positive caster when paired with matching lowers - improving straight-line stability and mitigating camber issues on drag cars.
These upper arms replace factory components directly and pair with TRZ stock-spring lowers or coil-over lowers depending on your build. Lower control arm choices can influence ride height, with TRZ options dropping the front end anywhere from 1.5" to 3" depending on configuration and spring selection.
Note: TRZ A-arms are engineered for drag racing only and do not include sway bar tabs. Not for street use.

Frequently Asked Questions
Can I achieve 6 - 7 degrees of caster with uppers only?
Not typically. Those caster numbers require the complete TRZ upper and lower control arm kit. Uppers alone may not achieve full caster and could create alignment limitations.
Are these suitable for street-driven Chevelles?
No. TRZ A-arms are drag-race-only components and do not include sway bar tabs. They are not intended or approved for street use.
