I've got 4 sets of these on sale for $399.99
The UCA’s are adjustable replacement arms offering extra clearance between the tire and control arm as well as in the front spring area. The arms use a larger heavy duty ball joint with a rubber boot to keep moisture and dirt out, while keeping the grease in, thus preventing noise. They feature adjustable camber and caster so alignment on any lift can be dialed in perfectly. They will work with any lift that uses the stock arms yet there is no need for longer CV’s. They will also add some more flex too due to the increased ball joint size and travel.
