Mugen Seiki MTX-4 Rear Differential Housing - CNC Aluminium MTX4-32/TI by 3Racing  [MTX4-32/TI]

Rear housing description

Designed as a direct replacement for the Mugen Seiki MTX-4 chassis, this CNC-machined aluminium rear differential housing is supplied under part MTX4-32/TI. The component swaps the original housing for a stiffer aluminium unit to help maintain consistent rear drivetrain geometry during setup and running.

This housing is suited to builders who prioritise chassis rigidity and dependable differential alignment for handling and gear engagement stability. It provides the mechanical mounting for the rear differential and mates with bearings, output cups, and the MTX-4 rear gearbox; verify bearing seating and clearances before final installation.

The aluminium housing can reduce flex under load and help preserve gear mesh during repeated adjustments, but it does not alter gear ratios or differential internals. Proper tuning still depends on your chosen diff parts and oil viscosities.

Opt for this aluminium housing when you need a robust replacement for the MTX-4 rear diff mount; ensure compatible bearings and internals are used when assembling the drivetrain.
