Aluminium rear knuckles engineered for Rustler VXL

The RUS4022 delivers a matched pair of aluminium rear knuckle arms for TRAXXAS 1/10 Rustler VXL, designed as a robust replacement for the original plastic items. Fabricated from 6061 T6 aluminium, the components increase strength without excessive weight, and include Delrin collars to tighten the hub fit and reduce lateral play.

Machined bearing seats narrow the gap at the wheel joint so the rear wheel rotates with steadier consistency under load. The knuckles serve to stabilise the upper and rear lower arms and the axle interface, which supports predictable rear track behaviour during acceleration and cornering.

These knuckles are intended as a direct swap for compatible Rustler VXL rear hubs; confirm bearing seating and collar alignment during reassembly to preserve geometry. Changing arm mass will affect rotational inertia and can subtly alter handling, so recheck clearances and fastener torque after fitting.

Specifications

  • Item Rear knuckle arm set, 2 pcs

  • TRAXXAS Rustler 4X4 VXL

What items arrive with the knuckle set?

You will receive two aluminium rear knuckle arms as a 2pcs rear set, ready for installation.

Are these stronger than stock parts?

Yes, 6061 T6 aluminium offers greater tensile strength than standard plastic knuckles, improving durability and hub stability.

Is any setup needed after swapping?

After fitting check bearing seating, collar position and screw torque; confirm there is no binding through suspension travel.

Will this affect wheel spin or cornering?

Expect improved hub stability and reduced play with only modest changes to inertia; handling differences are subtle and largely depend on overall setup.
