Axial Racing SCX24 Aluminum Rear Axle Differential Housing by JAZRIDER JR-SCX2405-BK  [JR-SCX2405-BK]

Aluminum rear axle differential housing

This replacement rear axle differential housing is an RC-scale spare intended for the Axial Racing SCX24 chassis. Manufactured in aluminum, the part is presented as a direct-fit option to address play and flex in the stock plastic housing and to provide a firmer mounting point for the rear drivetrain. The description focuses on compatibility, fit considerations, and the role this part plays when tuning for low-speed trail and rock crawling performance.

The housing is designed as a chassis-level hop-up: it changes the mechanical stiffness and contact points that affect how the differential sits under load. Hobbyists use this style of aluminum housing to reduce deformation under torque, to stabilise gear mesh, and to create more predictable handling in technical, low-speed sections of trail. As with any metal replacement, verify alignment with existing bearings and diff internals before final assembly.

Installation notes: confirm that your SCX24 rear differential internals and mounting screws match the replacement housing dimensions. Inspect mating faces and bearing seats during mock assembly and run a static check of gear mesh before re-installing to avoid premature wear. Routine maintenance and appropriate lubrication remain important after upgrading to an aluminum housing.

For scale trail builds that prioritise low-speed precision and drivetrain stability, this aluminum rear axle differential housing offers a durable alternative to the stock component; confirm fit with your SCX24 internals and proceed with routine setup checks after installation.
