Precision Rear Knuckle Arm Upgrade for Traxxas Rustler VXL

This GPM RUS4022 rear knuckle arm set provides a precision upgrade path for the Traxxas 1/10 Rustler VXL. Manufactured to deliver stiffer mounting points and tighter rotational tolerances, the parts are suited to hobbyists focusing on reliable handling under load.

Technical Highlights

  • Material Quality: Aluminum 6061 T6 construction yields a strong yet lightweight component ideal for durable suspension links.
  • Enhanced Fit: Integrated Delrin collars reduce axial play and promote consistent bearing seating for repeatable performance.
  • Precision Engineering: Optimised bearing location limits clearance to ensure smooth rotation of rear hub assemblies and improved tracking stability.

Packing includes

  • Rear Knuckle Arm - 2pcs

Compatible Models

  • Traxxas Rustler VXL

What machining tolerances are relevant for these arms?

Consistent bore alignment and flat mounting faces are critical; the RUS4022 design reduces play by controlling bearing seat location and collar fit.

Do these arms change load transfer through the rear suspension?

Stiffer aluminium knuckles limit flex at pivot points, improving load transfer to the chassis and maintaining more consistent wheel camber under torque.

Are Dowels or shims required for installation?

The parts are designed to fit existing Traxxas mounting geometry; use the supplied Delrin collars for correct spacing and check bearing seating during assembly.
