Stiff aluminium knuckles for E-REVO

This aluminium front/rear knuckle arm kit is built for the TRAXXAS E-REVO and comes with NMB bearings fitted where specified. Manufacturing targets tight tolerances to reduce steering slop at linkages and the wheel spindle interface on the E-REVO chassis.

On-track the knuckles serve as the steering pivot and hub support; switching to aluminium with integrated NMB bearings reduces play at mounting points and helps maintain consistent steering alignment under load or during tuning sessions. Compare to stock parts before final installation.

Packing includes

  • Delrin screw - 4pcs
  • Dust proof cap - 4pcs
  • Hex dust cap - 4pcs
  • 10x1.5 O-ring - 4pcs
  • 6x13x5 NMB bearing - 2pcs

Specifications

  • Item TRAXXAS E-REVO Aluminium Front/Rear Knuckle Arm with NMB bearings - 1pr set
  • Material Aluminium
  • Model Number GPM ER021B
  • Compatibility TRAXXAS E-REVO

Use the included screws, dust caps and O-rings to preserve sealing and alignment; check bearing fit and free play after mounting and again after your first run.

Will aluminium knuckles affect durability?

Aluminium improves stiffness and reduces flex; durability depends on driving style and impact events, so inspect parts after heavy use.

Are the dust caps essential?

Yes, use the supplied dust caps to protect bearings and retain alignment under dirty or wet conditions.

Can these be used with aftermarket hubs?

They are designed for E-REVO interfaces; confirm geometry and mounting dimensions with any aftermarket hub before fitting.

How often should bearings be serviced?

Inspect bearings after each outdoor session, clean and re-lubricate as needed, and replace if you detect play or rough rotation.
