Set Up Your Off-Road Shocks with Yokomo S4-SB1325

Engineered for off-road use, the Yokomo S4-SB1325 blank piston fits 13mm SO/MO shock absorbers and has a 2.5mm thickness. The guide marks make it straightforward to drill 2 to 6 holes with a pin vise so you can adjust damping feel across rough tracks.
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 piston fit SO and MO 13mm shocks?

Yes, the blank piston is intended for 13mm SO and MO style shocks and works with the compatible shock bodies listed for the series.

How should I choose the number of holes to drill?

Start from the middle of the 2 to 6 hole range and test. Fewer holes generally reduce flow while more holes increase flow, so trial and error on your setup will find the right balance.

Any tips for keeping oil clean after drilling?

After drilling, remove burrs and wash the piston to clear any metal shavings before assembly to prevent contamination of the shock oil.
