Engineered aluminium knuckles for consistent gear mesh

This 14pcs set of aluminium front knuckle arms has been engineered for TRAXXAS TRX4 Trail Crawler scale applications to provide increased support to steering linkages and internal front knuckle gears, ensuring consistent gear runs during slow technical crawling.

All components are CNC machined from aluminium 6061 T6 with a streamlined finish to maintain precise geometry under load and to minimise deformation. The aftermarket replacement reduces slop at knuckle pivot points and helps preserve smooth gear engagement during low-speed manoeuvres.

Stainless steel fasteners referenced by the product source are provided in multiple sizes to secure the assemblies; inspect the supplied hardware prior to installation and use appropriate thread engagement and locking methods to protect aluminium threads.

Product Reviews

rating
The quality is good and both the delivery and the reception of the order, fast. I can not give more stars, because the price of each component is high, the cost of shipping very high, discounts for good customer null, and generic discounts, to use only

What precision tolerances should I expect?

Components are CNC machined to maintain tight dimensional control for repeatable pivot locations and consistent gear mesh; inspect parts for burrs and ensure bearings and pins seat fully during assembly.

Recommended torque and threadlocking?

Use moderate torque appropriate for aluminium hardware and medium-strength threadlocker on stainless-to-aluminium joints where permanent retention is desired; avoid over-torquing to prevent thread deformation.

Compatibility and fit verification steps?

Verify knuckle pin diameters, bearing fits and screw thread sizes against your TRAXXAS TRX4 Trail Crawler chassis before final installation to ensure correct alignment and function.
