MTX4 2nd Stage Performance Housing MTX3-017 by 3Racing  [MTX3-017]

Precision second-stage housing for MTX4 transmission

This 2nd gear housing is a purpose-built replacement for the Mugen Seiki MTX4 chassis and is designated MTX3-017. It locates the second-stage spur and bearing stack within the MTX4 gearbox and is intended for maintenance cycles, component replacement, or a gearbox rebuild where accurate second-stage alignment is required.

Compatibility is limited to the MTX4 gearbox architecture; confirm chassis layout prior to ordering. During installation ensure gear mesh, backlash, and bearing preload are reset to match original settings to maintain even tooth contact and minimise wear. Inspect gear faces and bearing surfaces during the swap and replace any components that show wear or deformation.

Use this housing to reinstate correct second-stage geometry and running clearances for reliable drivetrain performance on MTX4 gearboxes.
