Adjustable Rear Upper Control Arms for 1968-1972 GM A-Body [Polyurethane Bushings, Black Powdercoat]
Color:
Dialing in rear pinion angle on a classic A-Body usually means unbolting the control arms to adjust them. These UMI upper control arms use an on-car CrMo adjuster instead, so pinion angle can be tuned while the arm stays bolted to the car, cutting installation and tuning time significantly.
UMI Performance 4025 Features:
- On-car adjustment using a UMI-designed and manufactured CrMo adjuster.
- Greaseable polyurethane bushings with zinc plated steel sleeves.
- CrMo threaded adapters for improved thread strength.
- 1/4 in. thick CNC laser cut upper mounting pads.
- Durable powder coat finish.
- Made in Philipsburg, PA, USA.
Bolt-On Replacement
UMI Performance Rear Upper Control Arms are direct bolt-on replacements designed to minimize wheel hop, improve cornering, and help track consistency. These TIG & MIG-welded control arms include polyurethane bushings, spherical rod ends, and Roto-Joints.
