Fine Tuning the Yokomo S4-018SA for Track Performance

The Yokomo S4-018SA shock tower spacer is a compact tuning part aimed at drivers who want tighter control over their YZ-4S chassis. By providing consistent spacing it helps stabilise suspension geometry for cleaner laps.

Track Stability and Handling Gains

Made with the YZ-4S in mind, the S4-018SA lets you make small, repeatable adjustments to shock location so the car stays balanced through fast corners and sweeping sections. It is suited to racers chasing predictable behaviour from their setup.

Fitment and Simple Installation

The S4-018SA spacer fits B-YZ4SF2-1, MOR-010, and MOR-020 chassis platforms, offering flexible use across common YZ-4S builds. Installation is straightforward and enables quick setup changes between practice and race conditions.
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.

Which chassis will accept the S4-018SA spacer?

The spacer is compatible with the B-YZ4SF2-1, MOR-010, and MOR-020 chassis types commonly used with the YZ-4S.

How does the spacer change on-track behaviour?

It adjusts the shock mounting spacing to refine camber recovery and roll centre, which can yield more consistent turn-in and mid-corner balance.

Any tips for fitting the spacer quickly at the track?

Remove the shock assembly, fit the spacer to the tower, then reattach and check shock travel and tyre clearance before running. Keep original screws and torque evenly.
