Durable Spur Gear for YZ-4 - Yokomo Z4-SG87

The Yokomo Z4-SG87 is a 48 pitch, 87 tooth spur designed to meet the needs of 4WD off-road drivers. It delivers steady power transfer and predictable gear mesh in the YZ-4 drivetrain. Whether replacing a worn part or preparing a car for club racing, this spur is built for straightforward installation and consistent service.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

Is special tooling required to fit the spur?

No special tools are required beyond common RC hand tools. Ensure correct mesh and secure fastenings when swapping spurs on a YZ-4 chassis.

Will this change my gearing ratio?

The tooth count determines the ratio. Replacing like for like with an 87T spur maintains the same ratio; changing tooth count will alter top speed and acceleration characteristics.

How often should I inspect the spur?

Check the spur after heavy runs or any impact. Regular inspection every few sessions helps catch wear early and avoids drivetrain damage.

Can I tune mesh for quieter running?

Fine-tune pinion position to reduce backlash and use light grease to quiet the mesh. Proper alignment is the best way to reduce noise and extend component life.

Does tooth profile affect handling?

Tooth count and pitch affect gear engagement and response. The 48P 87T combination offers a balance that keeps drivetrain response predictable for most off-road tracks.
