| RZR Rear Chassis Ribs RZR Chassis Ribs add strengh to the rear of your chassis by bracing the sides of the chassis together with the existing factory holes and by also tying into the upper and loser A arm mounting points. The Chassis Ribs are Laser Cut from 3/6 inch thick steel. For the upper A arm mounts instead of simply welding a washer to a chopped tube like some manufacturers may do we CNC machine a stair stepped end pieces that centers itself inside the tube and provides us a gap for a flush tig weld that evenly penetrates both pieces. Chassis ribs come in a durable black powder coat finish.
