Axial Racing SCX24 Aluminium Rear Diff Housing for Handling and Tune - JR-SCX2405-BK by Jazrider  [JR-SCX2405-BK]

What the aluminium rear housing changes

This replacement rear axle differential housing is an aftermarket upgrade for the Axial Racing SCX24 chassis, produced in aluminium to reduce flex and provide a firmer mounting point for the rear drivetrain. It is aimed at drivers who tune for predictable low-speed trail and rock crawling performance.

As a chassis-level hop-up, the aluminium housing alters stiffness and contact points that influence differential seating under torque. Model builders fit these parts to stabilise gear mesh and refine handling during technical sections. Before finishing assembly, double-check bearing alignment and diff internals to ensure smooth operation.

Setup tips: test gear mesh and driveline movement after installing the housing, and make incremental adjustments to pinion or gear spacing to dial in the desired response. Continue routine lubrication and inspections to sustain performance after the upgrade.

A practical upgrade for pilots refining crawl tuning and low-speed control, the aluminium housing offers improved drivetrain stability; verify fit and fine-tune gear engagement during setup.
