Precision Brass Pendulum Knuckles for Professional Trail Tuning

Engineered to improve low speed traction, the GPM brass pendulum wheel knuckle for the Traxxas TRX4 uses a calibrated pendulum mass to provide constant downward force and steadier tyre contact on uneven terrain.

Performance and Serviceability

  • Enhanced Stability: Stainless steel rolling beads at 4g each enable precise wheel mass adjustment, giving a practical range of 66 to 86 grams per wheel to fine tune balance and roll behaviour.
  • Durable Construction: Corrosion resistant stainless components are specified for longevity in wet or dirty operating conditions while maintaining reliable movement.
  • Increased Width: The supplied 23mm hex adapter increases track width by 18mm, improving lateral stability for technical crawling.

Packing includes

  • 23mm Hex Adapter - 2PCS
  • Stainless Steel Screw Shaft M4x2.5x11.8 - 2PCS
  • 5mm Stainless Steel Shims - 2PCS
  • 5mm Metal Washer - 2PCS
  • 20mm Stainless Steel Hex Socket Screws - 2PCS

Compatible Models

  • Traxxas TRX4

What is the effective weight range achievable per wheel?

Using the 4g stainless beads you can adjust wheel mass within the documented 66 to 86 gram range to optimise traction and roll recovery for different trail profiles.

Are the materials chosen to resist corrosion during field use?

Yes. Stainless steel parts have been selected to reduce corrosion risk in wet and muddy conditions, improving service life and reducing maintenance intervals.

Any setup advice for fitting the 23mm hex adapter?

Verify adapter seating and wheel clearance after installation, and confirm fastener torque. The 18mm increase in track width affects wheel offset and may require minor alignment checks.
