Center shaft upgrade for LAZER ZX fitment

This Kyosho LAW78B center shaft is an RC-scale replacement part named in the product title, offering a 7075 aluminum option sized to 77.5mm for LAZER ZX series models. Hobbyists often pick 7075 for its higher rigidity compared with standard alloys.

In operation this shaft links center gear components in on-road RC drivetrains; swapping to an aluminum shaft will influence drivetrain stiffness and response, so plan to check alignment and bearing condition when installing. Follow standard RC maintenance: inspect mating splines, verify clearances, and use an RC-safe grease on metal-to-metal contact points.

Installation notes: confirm LAZER ZX series compatibility before fitting, remove the old shaft carefully to avoid upsetting adjacent bearings, and tighten retaining hardware to the chassis maker's recommended torque. Adjustments elsewhere in the drivetrain may be needed after changing material to preserve smooth performance 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 shaft fit my LAZER ZX chassis?

The product title indicates fitment with LAZER ZX series; confirm the LAW78B part number against your chassis parts list or service manual to ensure the correct replacement for your specific variant.

How does 7075 aluminum change drivetrain feel?

7075 aluminium offers higher strength and stiffness, commonly producing a crisper drivetrain response and reduced flex. Expect subtle changes in feel and potentially different wear behavior compared with softer alloys.

What tools do I need to swap the shaft?

Basic RC tools such as hex drivers and a bearing puller are typically sufficient. Clean splines, lightly grease contact areas, and check alignment during reassembly to avoid binding.

How should I inspect the shaft for wear?

Regularly check splines and bearing seats for scoring or deformation, keep surrounding bearings clean and lubricated, and replace the shaft if you detect significant wear or damage.
