These are factory replacement Lower A arms for the Polaris RZR 1000 XP! These A arms are built out of thick wall DOM tubing and utilize factory ball joints and bushing. With our new design the Lower ball joints are moved forward slightly to help with easier steering and better self correcting. With 2 bends in the A arms, we have accomplished the most clearance possible while retaining strength greater than that of factory A arms. Uses O.E.M. Bushings and Ball Joints.
