Durable center shaft for LAZER ZX applications

The Kyosho LAW78B center shaft is supplied as a 77.5mm 7075 aluminium replacement for LAZER ZX series on-road models, intended for users who need a tougher drivetrain component. The 7075 alloy is favoured where higher resistance to deformation is desired.

This shaft connects central gear elements in on-road RC drivetrains; upgrading to aluminium will affect stiffness and resilience under load, so inspect bearings and alignment during the procedure. Standard RC care applies: clean mating surfaces, check spline engagement, and apply appropriate metal-safe grease.

Fitment advice: verify LAZER ZX series compatibility before removing the original shaft, extract the old part carefully to protect adjacent bearings, and set retaining hardware to the chassis maker's torque values. Monitor the system after installation for any signs of unusual wear.
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 resistant is 7075 aluminum to repeated club use?

7075 aluminium provides improved strength and wear resistance compared with softer alloys, making it suitable for frequent running. Regular inspection remains important to catch any fatigue or damage early.

Is this shaft appropriate for everyday practice sessions?

Yes. It is built to withstand regular use, but ensure bearings and gear mesh are maintained to prevent premature wear caused by misalignment or contamination.

Can I reuse my existing bearings with this shaft?

You can typically reuse bearings if they are in good condition. Clean and inspect bearing races for pitting or play before reassembly, and replace any bearings showing wear.

What warning signs indicate replacement is needed?

Look for visible scoring, bent splines, unusual vibration, or increased play at contact points. Any of these signs suggests it is time to replace the shaft.
