ZX7.5 diff case: compatibility notes

The LA402-01 Diff. Gear Case Set from Kyosho is a replacement housing specified for the LAZER ZX7.5 differential assembly. It secures the internal bevel gears and bearings and is intended as a direct-fit option for ZX7.5 diff components when the chassis calls for that layout.

Confirm your vehicle uses the LAZER ZX7.5 diff arrangement before fitting. Installation necessitates gearbox removal to access the differential, transferring gears and bearings into the new case, and confirming clearances during reassembly. A basic hex driver set will usually cover the job; attention to bearing seating and correct gear mesh is important for longevity.

Although the replacement shell does not change gear ratios, it impacts how the diff is serviced and maintained: tidy bearings, correct torque on fasteners and clean mating faces help preserve predictable differential operation. After refitting, carry out a brief low-speed run to check for smooth rotation and correct engagement.
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.

Can this housing be used in variants of the ZX7.5 chassis?

Use only on chassis that match the LAZER ZX7.5 differential layout. Some variants may use different diff mounts or gearbox spacing, so cross-check measurements and mounting points before fitting.

Should I replace bearings when fitting the new case?

Inspect bearings for wear and replace any that show pitting or roughness. Fresh or well-conditioned bearings ensure correct preload and reduce the risk of handling-related issues after the swap.

How do I verify correct gear mesh after reassembly?

Check backlash across the bevel gears and listen for binding under slow rotation. Adjust bearing seating or shims if available until the mesh runs smoothly without excessive play.

Any final inspection tips post-install?

Ensure all screws are properly seated, confirm bearings rotate freely and that there is no lateral play, then perform a controlled low-speed test to validate correct differential behaviour.
