Aluminium knuckle arm for E-REVO

This aluminium front/rear knuckle arm set is designed for the TRAXXAS E-REVO platform and includes pre-installed NMB bearings where specified. The parts are manufactured to provide close tolerances for steering linkages and wheel spindle interfaces on the E-REVO chassis.

In practical RC setup the knuckle arms act as the steering pivot and support the wheel hub assembly; using aluminium with integrated NMB bearings reduces play at the mounting points and helps maintain consistent steering geometry during aggressive runs or tuning changes. Check fitment against your stock knuckles 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 when installing this set to retain sealing and alignment; verify bearing orientation and free play after assembly and during initial test runs.

I have recently ordered from gpm for traxxas e revo parts,they are still in transit at this moment but what I can say is the level of service I have received has been second to none..thank you gpm racing,in particular Zoe from customer service for your qu

Will these knuckles fit stock TRAXXAS E-REVO hubs?

They are produced for TRAXXAS E-REVO compatibility, verify the stock spindle and hub interface match before final installation.

Are bearings included and replaceable?

The kit includes 6x13x5 NMB bearings, these are standard sizes and can be replaced with the same specification if needed.

What maintenance is recommended after installation?

Inspect bearing play and dust caps regularly, re-check screw tightness after initial runs, and clean bearings as part of routine maintenance.

Do these knuckles change steering geometry?

The arms are intended as direct replacements; any change in geometry is minimal but final geometry depends on your overall setup and should be checked during tuning.
