Precision aluminium knuckles for E-REVO steering

These aluminium front and rear knuckle arms are made for the TRAXXAS E-REVO platform and come with specified NMB bearings pre-installed. Components are produced to tight tolerances to minimise play in steering linkages and wheel spindle interfaces on the E-REVO chassis.

In everyday RC use the knuckle arms form the steering pivot and support the wheel hub; aluminium construction with integrated NMB bearings reduces unwanted movement at mount points and helps keep steering geometry consistent during hard runs or setup changes. Always compare fitment with your stock knuckles before final assembly.

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

Use the supplied screws, dust caps and O-rings for correct sealing and alignment; check bearing orientation and free play after assembly and again during initial test runs to confirm correct installation.

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 ER021B bolt straight onto stock E-REVO spindles?

They are manufactured for TRAXXAS E-REVO fitment, but measure your stock spindle and hub interface to confirm compatibility before final installation.

Are the included NMB bearings standard and serviceable?

The kit ships with 6x13x5 NMB bearings which are standard sizes and can be replaced with equivalent bearings if required.

How should I check for play after fitting?

After assembly, rotate the hub and move the wheel laterally to check bearing clearance, then re-tighten screws and re-check after a short test run.

Will these change my steering geometry noticeably?

They are designed as direct replacements so geometry change is minimal; any differences depend on your full suspension setup and should be tuned accordingly.
