Aluminium knuckle arm summary

This aluminium front/rear knuckle arm set is an aftermarket replacement made for TRAXXAS E-REVO style chassis and is supplied as one left and one right piece. The machined aluminium construction aims to reduce steering tolerance and maintain a firm connection between the steering link and the wheel hub so geometry stays consistent when loaded.

The part is intended for scale RC use and is compatible where TRAXXAS E-REVO style knuckles are used. Mounting points match the stock plastic parts; reuse OEM hardware where applicable and check for clearance around hex dust caps and dust-proof caps. Fitment is tight with minimal play, delivering crisper steering response while setting up and tuning the vehicle.

The package contains service items for installation: Delrin screws together with several dust caps and O-rings to help keep seals in place around pivots during off-road running.

Specifications

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

Fit these knuckle arms for a durable, low-play alternative to plastic that aids steering precision and predictable handling during setup sessions.

Will these accept stock steering rods and ball joints?

They are designed to share the same mounting geometry as the OEM knuckle arms, but always double check ball stud placement and rod lengths before final tightening.

Does the kit include spare seals or fasteners?

Yes, the set includes Delrin screws, dust caps and O-rings to aid assembly and help protect pivot seals from dirt ingress.

Are any adjustments required for big wheels?

Large wheels or non-standard hubs can require a clearance check; verify there is no contact with the knuckle or dust caps when steering lock is applied.

What benefit does aluminium give over plastic knuckles?

Aluminium reduces flex and unwanted movement at the knuckle pivot, giving steadier, more repeatable steering inputs which helps when fine tuning suspension and toe settings.
