TRAXXAS 1/10 Rustler VXL Rear Knuckle Arms Aluminium RUS4022 by GPM  [RUS4022]

Aluminium rear knuckle upgrade for Rustler VXL

The RUS4022 set provides two aluminium rear knuckle arms built for TRAXXAS 1/10 Rustler VXL rigs, intended to replace the standard plastic units with a more robust option. Constructed from 6061 T6 aluminium, they offer improved tensile strength while keeping weight sensible, and include Delrin collars to firm up the hub interface and reduce side play.

Machined bearing seats ensure minimal gap at the wheel joint so the rear wheel tracks with steadier rotation under load. The knuckles stabilise upper and rear lower link positions and the axle connection, helping the rear track remain predictable when accelerating and negotiating turns.

Installation is a straightforward swap for compatible Rustler VXL rear hubs; verify bearing fit and collar seating as you reassemble to maintain correct alignment. Remember that altering arm mass will influence rotational inertia and handling nuance, so check clearance and hardware after fitting.

For a durable rear hub upgrade on the Rustler VXL, this pair improves fitment and reduces play while staying easy to fit.
