These are factory replacement Lower A arms for the Polaris RZR 900 XP! These A arms are built out of .120 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. Allow up to 7-10 days for custom fabrication parts to be built, powder coated, and shipped. Most parts will be shipped sooner and in the event that shipping is delayed you will be contacted via email or phone call.
