Machined aluminium knuckles for E-REVO

This 8 piece knuckle arm set is made to replace the factory plastic knuckles on TRAXXAS E-REVO, moving the suspension pivot to precision 6061 T6 aluminium with POM collars to tighten bearing fit and reduce slop for crisper steering response.

The kit includes knuckle arms together with stainless steel round head screws 3x20 and Delrin locknuts to secure the assembly and resist loosening under load. POM collars protect bearings from direct friction and keep them seated during aggressive driving.

Multiple tie rod and steering link mounting holes allow you to tune steering geometry for different setups, and the alloy knuckles help to stabilise both front and rear arms plus the CVDs for more consistent steering feel after installation.

Specifications

  • Item: Front and rear knuckle arms set, 8 pcs
  • Material: 6061 T6 aluminum body, POM collars, Delrin locknuts, stainless steel screws
  • Model Number: ER021N
  • Compatibility: TRAXXAS E-REVO

Replace worn plastic knuckles with these aluminium arms to reduce play and enable finer steering geometry adjustments; always verify fitment and torque settings during assembly.

Will these bolt onto the stock E-REVO hubs?

They use the same mounting pattern as the stock parts, but check hole alignment and bearing seating before final torque to ensure a correct fit.

What hardware is supplied with the knuckles?

The set ships with the aluminium knuckles plus stainless steel 3x20 round head screws and Delrin locknuts as listed in the kit contents.

How do the POM collars improve bearing fit?

POM collars act as low-friction spacers that reduce radial play and hold bearings tight in the knuckle bore, cutting unwanted movement during steering.

Can I change steering geometry with these arms?

Yes, the extra mounting holes give several tie rod positions so you can alter ackermann and steering ratio to suit tyres, track surface and driving style.
