  • Durability: Built from reliable materials suitable for frequent tuning.

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.

How do the 1.8mm holes change damper feel?

The 1.8mm ports restrict oil flow compared to larger holes, producing firmer compression and a more controlled rebound that helps on smoother surfaces.

Are any special tools required to fit them?

No special tools are needed beyond basic shock service items like a shock spanner and clean oil; work on a bench to avoid contaminants.

Will these pistons affect tyre wear or handling balance?

They change damper response which can influence weight transfer and tyre load; tune oil and spring rates together to maintain balanced tyre wear.
