GPM Racing Brass 7mm Wheel Hex Hub Extenders (+1.5mm) for Traxxas 1/18 TRX-4M (TRX4M010X/7)

Precision 7mm brass hex extenders for TRX4M platforms

This 7mm brass wheel hex hub extender set is manufactured as an upgrade part for TRAXXAS TRX4M models. The CNC-style profile provides a consistent +1.5mm offset and functions as both front and rear hex adapters to couple the front CVD and rear driveshaft to the wheels without modifying axle housings.

Brass delivers reliable surface hardness and predictable wear characteristics suitable for scale crawling. The compact geometry allows small track correction and improved wheel-to-body clearance while keeping installation reversible. Fitment is achieved by replacing the factory hex and securing the adapter with the supplied 1.5×5.8 retention pins to maintain axial location under normal trail loads.

These extenders are intended for precision tyre fitment adjustments and stance tuning on 1/18 TRX4M scale chassis while maintaining serviceability and alignment integrity.

What are the service considerations for brass extenders?

Inspect the hex faces and pin bores for wear after extended rock crawling, clean contact faces, and replace pins if deformation or elongation appears.

How precise is the offset and fitment?

The adapters are produced to tight dimensional tolerances to maintain a consistent +1.5mm offset and repeatable keyed engagement with standard TRX4M hex hubs.

Do these require axle housing work?

No axle housing modification is necessary; the design connects to existing hub and driveshaft interfaces using the supplied retention pins. Write Product Review Please sign in your account before you can write any review. Sign In Close
