SuperATV Polaris RZR 4 900 2" Forward Offset Boxed A-Arms give your Polaris RZR 4 900 a 2-inch forward offset and 1.5 inches of extra ground clearance. Built from 1/8-inch steel plate that is stronger than the stock arms, they make room for up to 30-inch (33-inch with 1.5-inch rear offset arms) tires, and a UV-resistant powder coat finish keeps them looking good after hard rides on trails, farm roads and washouts.
Choose a preinstalled ball joint option and SuperATV presses the joints in before the arms ship, or reuse your existing ball joints. The adjustable pivot blocks let you dial in camber after adding a lift or bigger tires.
This SuperATV Boxed set is built specifically for the Polaris RZR 4 900 models listed below, so the geometry matches your machine.
