These arms are designed to change factory suspension pickup points to induce negative camber as the wheel goes up into the fender. The extra negative camber generated by the arms will keep a greater portion of the tire on the ground, which increases the vehicle's cornering ability.

Highlights

Better geometry curve

Built-in bump stops

Load carrier ball joints

Special billet offset shafts

Installation Notes

When using the arms on GM A-bodies, GM tall spindles, machined lower ball joints, and different outer tie rods are required. For 1964-70 A-bodies, use outer tie rod part #459-3007; for 1971-72
A-bodies, use #459-3008.

Negative roll systems will drop the front ride height 1 inch because of the taller spindle and lower ball joint combination. The maximum backspacing on 1964-72 A-bodies is 5-7/8" with a 17" wheel,
5" with a 16" wheel, and 4-1/2" with a 15" wheel.

When using the arms on GM G-bodies, GM tall spindles are required. Spindle tapers for this conversion are the same as the standard, shorter spindle.

Factory upper control arms cannot be used with negative roll systems because they are too long, and they won't allow for proper alignment.

Factory lower control arms can be used in negative roll systems, but they will require machined lower ball joints (part #459-2005).
