Technical overview of machined knuckles

This aluminium front/rear knuckle arm set is supplied as a matched left and right pair and serves as an aftermarket replacement for TRAXXAS E-REVO style chassis. The machined aluminium construction reduces steering tolerance and maintains a precise interface between the steering linkage and wheel hub to preserve geometry under load.

Installation follows OEM mounting points so existing factory hardware can be reused where appropriate; confirm clearance for hex dust caps and dust-proof covers prior to final assembly. The tight kit fit and low play deliver improved steering feedback for detailed setup work.

The delivery includes service items to aid assembly: Delrin screws alongside multiple dust caps and O-rings to help retain seals and protect pivot areas during off-road operation.

Specifications

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

Specified for hobbyists seeking a durable, low-tolerance replacement to improve steering precision and achieve more repeatable handling during tuning.

How does fitment compare to the stock knuckle arms?

The parts use the same mounting geometry as stock knuckles, designed for direct replacement; verify alignment of ball studs and link lengths when fitting.

Which small parts are supplied for assembly?

Included items are Delrin screws, multiple dust caps and O-rings to assist assembly and to maintain pivot sealing under typical off-road conditions.

Any recommended checks after installation?

Check for interference with aftermarket hubs and large diameter tyres, confirm smooth steering movement across full lock, and torque mounting fasteners to spec.

What steering characteristics will change?

Expect reduced flex and less free play at the pivot which yields firmer, more repeatable steering input useful for precise suspension and toe adjustments.
