Technical overview of JAZRIDER brass axle covers for TRX4M

The JAZRIDER Brass Front/Rear Axle Cover is a practical engineering upgrade for the Traxxas 1/18 TRX4M Bronco and TRX-4M Defender. Manufactured to provide added mass at axle termini, these covers improve static weight distribution and offer a protective interface for axle components exposed during trail use.

Design and performance considerations

Adding brass at the wheel ends increases unsprung weight in a controlled manner, lowering centre of gravity and improving tyre loading on uneven terrain. The black finish reduces surface oxidation and provides a consistent mating surface for the vehicle chassis when used in rugged conditions.

Fitment, installation and serviceability

Components are profiled to integrate with stock TRX4M axle features for a secure fit with minimal modification. Fastener access and part geometry support straightforward removal for routine inspection and maintenance, making these covers suitable for regular trail use and tuning iterations.

What impact does the added brass have on axle centre load?

The added mass shifts load outward and downward, improving tyre contact patches during slow-speed crawling and reducing propensity to rollover on steep side slopes.

Are there any recommended torque values for mounting fasteners?

Use moderate torque consistent with small alloy accessories; avoid over-tightening which can distort mating faces. Check fastener security after initial runs and periodically thereafter.

Can these covers be used with aftermarket locked axles?

Compatibility depends on axle diameter and end profile. Confirm dimensions against the aftermarket axle specifications before fitting to ensure correct seating and clearances.
