The Uniballs allow for increased wheel travel when paired with Dirt Logic Coilover shocks. The heat treated Stainless Steel Uniball pin is tapered to fit into the stock BJ taper for an easy return to stock feature.

For top level offroad performance, high quality FK 3/4" heim ends are offered to eliminate control arm deflection. These FK 3/4" heims create a solid mounting point to the frame for the UCA with unsurpassed longevity.
