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

Precision rear knuckle arms for Rustler VXL

The RUS4022 kit supplies two precision machined 6061 T6 rear knuckle arms intended as a robust aluminium upgrade for TRAXXAS 1/10 Rustler VXL rear hubs. The components use machined bearing seats to reduce axial and radial gap, while Delrin collars are provided to secure the hub interface and minimise lateral play.

Accurate bearing seating and tight tolerances improve wheel rotation consistency under load and stabilise the upper and rear lower link positions relative to the axle. The result is a more predictable rear track response during acceleration and in high load cornering situations.

Fitting is a direct replacement for compatible Rustler VXL rear knuckles; verify bearing positioning and collar seating during reassembly to maintain alignment. As standard practice, recheck fastener torque and suspension clearance after installation since arm mass changes can alter rotational inertia and handling balance.

For serious hobbyists seeking a durable, tightly fitting rear hub solution for the Rustler VXL, this RUS4022 pair balances strength and weight while retaining simple installation.
