Precision aluminium wheel and tyre assembly

This 12-piece kit is engineered as an aftermarket upgrade for the TRAXXAS TRX4, utilising CNC-ready 6061-T6 aluminium rims finished with a hard anodise and paired with low-profile onroad rubber and 9mm alloy hexes to increase track width while maintaining scale appearance. The six-spoke BBS design is machined for consistent fit and repeatable run-out control.

The 9mm alloy hex is specified to move the wheel hub outward for a wider stance without altering suspension pick-up points, improving lateral stiffness and delivering a more immediate steering response on firm surfaces. The design intent is compatibility with TRX4 mounting standards and serviceability with standard TRX4 bearings and hardware.

Installation guidance for builders: secure supplied wheel hardware to manufacturer torque recommendations, apply thread-lock on metal fasteners where appropriate, and verify bearing preload and pinion clearance to prevent drivetrain binding. Documentation references include manuals 8269, 8270 and 8271 for part identification and assembly diagrams.

A precision upgrade for TRX4 platforms where improved track width and a firmer onroad response are required without modifying suspension geometry.

What tolerances matter when fitting these rims?

Check hex bore concentricity, hub face clearance and bearing press fit; small misalignments can induce preload changes and drivetrain drag.

How should I treat aluminium contact surfaces?

Clean mating surfaces, use recommended thread-lock on steel-to-aluminium fasteners and avoid over-torquing to preserve anodised finish and part life.

Are these compatible with standard TRX4 bearings?

Yes, the parts are specified for TRX4 bearing housings; verify bearing condition and replace if worn to ensure correct preload and alignment.

What post-fit checks are recommended?

Recheck wheel run-out, bearing seating and gear mesh after initial assembly and first test runs to catch any seating or clearance issues.

Can these rims be serviced or refinished?

The anodised surface can be carefully cleaned and minor damage addressed, but deep scratches reduce corrosion protection and may require part replacement for best performance.
