Upgrade the rear end of your TRAXXAS TRX4 Trail Crawler with GPM TRX4022 aluminium rear knuckle arms. These knuckles keep the inner gears controlled to reduce slop and prevent gear bind during rough driving. Made from durable 6061 T6 aluminium and CNC machined for tight tolerances, they bring both strength and a refined metal finish to the axle assembly. Ideal for off-road use where reliability matters.
