TRAXXAS Rustler VXL Heavy-Duty Front Knuckles RUS021 by GPM  [RUS021]

Replacement Knuckle Details

This alloy front knuckle set is an aftermarket replacement for the TRAXXAS Rustler VXL front end, supplied as a single pair for 1/10 scale Rustler VXL vehicles. The knuckles serve as the steering pivot that attaches the wheel hubs and steering rods to the suspension assembly.

The alloy construction provides a firmer hub mounting surface, which limits deformation under lateral loads and helps maintain the intended steering geometry during aggressive driving or on rough terrain. The upgrade preserves original suspension geometry while improving part longevity.

Fitting involves standard front-end teardown on the Rustler VXL, removal of the stock knuckles, and transfer of hubs, wheel pins, and other hardware. Check hub seating and bearing clearance during installation to ensure wheels turn freely without binding.

Ideal when you need a tougher front knuckle that keeps the stock geometry intact while offering better resistance to wear and flex; verify fastener sizes and bearing fit during assembly.
