High-strength 7075 aluminium centre shaft for LAZER ZX

The Kyosho LAW77B centre shaft is offered as a spare for LAZER ZX series cars carrying the 71.5/7075/ZX7.5 identification. This driveline component replaces the original centre shaft to recover alignment and rotational stability through the transmission centre.

Forged from 7075 aluminium as shown in the part code, the shaft links gearbox components with increased stiffness while remaining a scale-correct replacement. It is a focused repair item for when wear, deformation, or bearing play undermine drivetrain smoothness and handling.

Installation emphasis should be on correct seating and bearing condition. While fitting, check mating faces and running clearances, examine nearby ball bearings and spur/pinion engagement, and confirm the shaft rotates freely prior to final assembly. Tuning small mesh and balance items will lessen vibration and improve consistency.

A maintenance-focused spare for LAZER ZX series models, providing a robust 7075 aluminium option for enthusiasts performing repairs or setup work.
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 do I confirm this fits my LAZER ZX?

Check your vehicle's parts diagram or the original centre shaft part code; the LAW77B is intended for LAZER ZX series but confirmation against your chassis list is recommended.

What performance change should I expect?

Using a 7075 aluminium shaft increases rigidity versus softer alloys, which can reduce flex under load and deliver a firmer drivetrain feel during aggressive tuning.

Any fitment pointers for workshops?

Ensure bearings are serviceable, clean mating surfaces, fit the shaft ensuring smooth rotation, then verify gear mesh and balance before track use.
