High-Precision Spur for YZ-4S Differentials

The Yokomo S4-SG84CDA is crafted for precise duty in YZ-4S center differentials. Its 84-tooth, 48-pitch profile helps maintain consistent power flow and dependable behaviour during competitive use.

Confirmed Fit for YZ-4S Series

Compatible with YZ-4S variants like B-YZ4SF and B-YZ4SF2-1, this spur gear installs without modification and keeps gear alignment stable under load. The build quality copes with repeated race conditions.

Accurate 48P Cutting for Long-Term Reliability

The 48-pitch teeth are machined to give a tight, smooth mesh with matching pinions, which reduces heat and wear. That accuracy results in better drivetrain efficiency and extended intervals between servicing.
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.

Will this replace the original YZ-4S spur gear directly?

In most cases yes; the S4-SG84CDA is made for the YZ-4S centre diff. Verify your diff mount and pinion combination before final assembly to ensure ideal mesh.

What signs indicate spur gear wear?

Look for rounded or chipped tooth edges, increased backlash, or abnormal noise under load. Address these early to avoid damage to pinions and bearings.

Should internal diff maintenance be done when replacing the spur?

It is a good opportunity to inspect diff bearings, gears and lubrication. Fresh lubricant and checked bearings help the new 48P spur perform at its best.
