Diff case upgrade designed for LAZER ZX7.5

This RC centre differential gear case set is intended for the LAZER ZX7.5 chassis. It takes the place of the existing centre diff housing, retaining the internal gears and maintaining correct mesh and drivetrain alignment.

What it does: the case secures bearings and shafts, retains the differential internals, and offers the mounting features that set preload and alignment. Replacing the case is a normal maintenance or repair operation after impact damage or when changing tuning geometry.

Assembly tips: confirm the new case fits your current centre diff and gearbox halves before final installation, clean mating surfaces and bearings, and check gear mesh and backlash after assembly. Do not trim surrounding components unless following specific LAZER ZX7.5 instructions.

Effect on tuning: installing a replacement case can influence centre diff alignment and the way diff oil and preload work. After installation, rotate the diff to ensure smooth operation and verify there is no unwanted binding under load.
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.

Will this replace a damaged centre diff housing on my LAZER ZX7.5?

Yes, it is intended as a replacement housing for LAZER ZX7.5 centre differentials. Ensure the chassis code matches your vehicle before fitting.

Do I need to re-shim after installing this case?

Recheck shims, backlash, and mesh after installation. Minor adjustments may be required to restore the original diff clearance and prevent premature gear wear.

How does a new case affect diff tuning?

Because the case determines alignment, it can change how diff oil and preload translate to on-track behavior. After fitting, test and adjust oil weight or preload settings as needed.

Is special tooling required to install this part?

No specialised tools are necessary beyond standard RC hand tools. Use correct hex drivers and a clean workspace to avoid contaminating bearings and gears.
