Precision engineered knuckles for consistent steering geometry

These GPM aluminium knuckle arms are machined to reduce flex at the hub and stabilise the CVD interface on the Traxxas E-Revo. The integrated POM collars firm the bearing seat to lower play and maintain accurate steering under load.

Technical benefits and tuning

  • Material Upgrade: 6061 T6 aluminium paired with POM collars yields improved stiffness and dimensional stability over stock plastic parts.
  • Improved Durability: Delrin lock nuts provide secure clamping and resist loosening in high vibration environments.
  • Secure Bearing Fit: POM inserts reduce bearing migration and isolate bearings from metal-on-metal wear.
  • Adjustable Installation: Multiple mounting holes allow fine tuning of tie rod geometry and knuckle angle to suit track or bashing setups.

Packing includes

  • Kncukle Arm - 2pcs
  • Stainless Steel Round Head Screw 3x20 - 2pcs
  • Delrin Locknut - 4pcs

Compatible Models

  • Traxxas E-Revo
Verify bearing axial play and ensure the POM collar seats flush; check that tie rod clearance is sufficient across full suspension travel.
Use moderate hand torque for the 3x20 stainless screws and retorque after initial runs; over tightening can distort the POM collars or strip threads.
Pair with uprated CVDs and hardened drive cups to fully benefit from the reduced flex and the improved bearing retention these knuckles provide.
