UMI Front Upper A-Arms Chevy Chevelle/El Camino 64-72 Black Tubular w/.5" Ball Joints

Improve front suspension geometry and steering control in 1964-1972 Chevelles and El Caminos. These tubular front upper A-arms feature 0.5" taller ball joints (4033-1-B). These increase caster and negative camber potential. These arms improve steering response, straight-line stability, and lateral grip throughout suspension travel. They have a relocated ball joint mounting pad. This allows up to six degrees of caster without excessive shimming. The taller ball joint provides additional negative camber at full bump. This improves tire contact during cornering. It is made from jig-assembled DOM tubing. It also has CNC-machined ball joint mounts and reinforced gussets. These A-arms include precision-machined Delrin bushings and 4140 chromoly cross shafts. These reduce deflection while maintaining smooth suspension movement. It is designed to work with factory spindles. It is also compatible with factory or UMI lower control arms.
