The stamped factory control arms have flimsy rubber bushingspressed in both ends. While an acceptable choice for the street,they are not ideal for performance minded driving. ALTA™ adjustablecontrol arms solve all of those problems without increased noise, harshness orvibration (NVH) associated with other adjustable control arms.

The ALTA Performance™ control arms are machined from billet6061t6 aluminum and threaded to accept heim joint ends.This eliminates unnecessary welding and extra pieces, further increasing strength.

Threaded into both control arms ends are huge aircraft quality, Nylon impregnated, rod ends. The Nylon impregnating prevents the ball from coming loose, causing a rattle, as well as constantly cleaning the bearing surface.

Two sets of arms can be purchased to replace both upper and lower control arms. This can further increase rear end adjustment, and remove even more deflection from the OEM rubber bushings. Doing so also removes unsprung weight from the suspension.

All these features add up to a part with both performance benifits, and durability that lasts forever.
