GM Pro G Tall 2" Dropped Steel Spindle
Product Description
Fits '67-'69 Camaro, '68-'74 Nova, *'64-'72 Chevelle* & GM A-Body

It is called a TALL Spindle because the upper ball joint is raised 1-1/2”. Different from the factory design, it yields a better camber change during suspension movement.

Pivot points are determined by the ball joints on the spindles and bushing locations on the frame, not the control arms. These spindles are STEEL, the strongest ones in the industry. Can not use drum brakes.

**Note** - Will Not Work With Previous OEM Drum Brakes.
