Performance oriented 4mm hex posts M4WD-02/GO for roller mounting

A compact 4mm hex post set designed for precise roller and bracket mounting on Mini 4WD chassis. These parts suit competitive builders who require repeatable post geometry for setup consistency across Super-II, MA and similar platforms. The gold finish serves as a quick visual aid for matched components during quick service intervals.

Setup notes emphasise clearance checks, common mounting orientations, and secure thread engagement: the posts act as a rigid standoff for roller assemblies and pair best with low-profile nuts and thin washers to minimise stack height. The design supports quick swapouts and consistent height control for tuned roller layouts.

Compatibility focuses on standard Mini 4WD components accepting 4mm hex posts. This aftermarket set does not modify wheel, motor, or drivetrain characteristics. Confirm post length and bracket hole sizing on the specific roller bracket before installing to ensure reliable race-day performance.

What is the best practice for ensuring consistent roller alignment?

Use the same post height and low-profile fastening hardware across matching mounting points. Verify perpendicularity of the post to the stay and confirm there is no lateral play after tightening.

How should I check thread engagement for race reliability?

Ensure several full turns of thread engagement remain inside the nut after final torquing. Avoid relying on minimal engagement that could loosen under vibration.

Which hardware pairs best with these posts?

Low-profile hex nuts or thin locknuts combined with thin washers reduce stack height and keep roller geometry consistent. Select hardware that matches the post thread size and intended clamp force.

Any tips for quick maintenance between heats?

Mark matched posts with the gold finish for fast identification, keep a spare set with identical heights, and verify nut torque and washer placement during quick pit checks.
