TRAXXAS 1/10 Rustler VXL Rear Knuckle Arm Set 6061 T6 RUS4022 by GPM  [RUS4022]

Heavy-duty aluminium rear knuckles for Rustler VXL

The RUS4022 kit includes two aluminium rear knuckle arms tailored for TRAXXAS 1/10 Rustler VXL builds, providing a tougher alternative to the factory plastic pieces. Made from 6061 T6 aluminium, the arms increase structural strength while keeping weight reasonable, and fitted Delrin collars minimise side play at the hub connection.

Carefully machined bearing seats reduce clearance so the rear wheel spins with steadier consistency under load. These knuckles help stabilise the upper and rear lower arm geometry and the axle interface, improving predictability in rear track behaviour during throttle and turns.

They install as a direct swap on compatible Rustler VXL rear hubs; check bearing positioning and collar seating as part of reassembly to maintain alignment. Keep in mind that changing arm mass alters rotational inertia and can subtly shift handling, so confirm clearance and torque after fitting.

This aluminium knuckle pair offers a straightforward way to firm up the Rustler VXL rear hub area and increase durability.
