Machined alloy knuckle summary

This aluminium front/rear knuckle arm set serves as an aftermarket replacement for TRAXXAS E-REVO platforms and is supplied as a single left and right pair. The machined aluminium construction aims to minimise steering slop and preserve a direct connection between the steering link and wheel hub so alignment holds up under load.

Intended for RC-scale applications where TRAXXAS E-REVO style knuckles are compatible, the arms mount to the same points as the OEM plastic items. Use original hardware when appropriate and confirm there is no interference with hex dust caps or dust-proof covers. The fitment is described as snug with low free play, giving crisper steering feel while tuning.

The package includes small service parts to help with installation: Delrin screws plus dust caps and O-rings to support seal retention at pivot areas during regular off-road use.

Specifications

  • Item: Aluminium Front/Rear Knuckle Arm set
  • Material: Aluminium
  • Model Number: ER021
  • Compatibility: TRAXXAS E-REVO

Fit these knuckles when you need a tougher, low-tolerance upgrade over stock plastic parts for more predictable steering and easier setup control.

Yes, they use the same mounting geometry as the stock knuckles, but always check ball stud height and link clearance during the install process.
The set ships with Delrin screws, multiple dust caps and O-rings to help with assembly and dust sealing.
Oversized wheels or certain hubs can create interference, so check clearance around the knuckle and dust caps before finishing the setup.
The aluminium parts reduce flex at the knuckle pivot, yielding a firmer, more consistent steering response which is useful when dialling in suspension settings.
