Centre diff housing crafted for LAZER ZX7.5 applications

This centre differential gear case set fits the LAZER ZX7.5 chassis. It replaces the centre diff housing, locates the internal gearset, and preserves proper mesh and alignment across the drivetrain.

Intended role: the case secures bearings and shafts, holds the centre differential components, and supplies the mount points that control preload and alignment. Replacing the housing is a standard repair following impacts or when updating tuning choices.

Practical installation notes: verify the case mates correctly with the existing centre diff and gearbox halves, clean all mating surfaces and bearings, and then recheck gear mesh and backlash after assembly. Avoid modifying adjacent components unless guidance for LAZER ZX7.5 explicitly calls for it.

Tuning considerations: changing the housing can affect centre diff alignment and the way diff oil and preload behave. After fitting, confirm the diff turns freely and that there is no binding when torque is applied.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How can I confirm this is the correct part for my vehicle?

Match the chassis code and part number on your model to ensure compatibility; this case is designed for LAZER ZX7.5 platforms and should be ordered only for matching vehicles.

What should I inspect on the diff before fitting the new case?

Check bearings, shafts, and gear teeth for wear or damage. Replace any components that show signs of fatigue to avoid premature failure after installing the new housing.

Will changing the case require me to retune the car?

Potentially. Because the housing sets the geometry, you should reassess diff oil, preload, and track feel after installation and adjust settings if necessary.

Are there any assembly pitfalls to avoid?

Avoid over-tightening fasteners which can warp the case, ensure clean bearings and surfaces, and test rotation and mesh before the first run following installation.
