GPM Racing Aluminium Front 12 Piece RC Knuckle Arms - GPM-UDR021

The GPM Racing UDR021 aluminium front knuckle arms are a direct-fit metal upgrade for the Traxxas Unlimited Desert Racer, replacing the factory plastic components with machined aluminium units. Sold as a 12-piece set under part number GPM-UDR021, these RC knuckle arms are designed for UDR owners looking to move away from plastic parts in the front steering assembly.
