Suspension Tuning for Big Shock Setups

This 1.3mm, 8-hole shock piston is made for big shock assemblies and helps refine damping response. Its 8-hole layout controls oil flow to produce measured compression and rebound behaviour, which helps drivers tune handling across smooth and rough surfaces.

When to Fit These Pistons

These pistons are a practical option for RC builders who want a straightforward change to suspension feel. Swapping in the Kyosho IF347-138 lets you temper the shock reaction for faster tracks or more uneven terrain, with the 1.3mm holes offering a balanced damping profile.

Fitment and Service Tips

Designed for big shocks, these pistons are compatible with many large shock bodies and are simple to install during routine maintenance. Clean seals and match the piston to the shock oil viscosity for stable performance and longer service intervals.
Remark :
Due to limited stock availability, please notice that some Kyosho 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 should I choose shock oil with the 1.3x8 piston?

Start with a medium viscosity oil and make small steps up or down while testing. The 1.3mm holes give a neutral baseline, so changes in oil weight will noticeably affect compression and rebound timing.

Will these pistons fit any big shock on the market?

They are built for big shock types and match many common shock bodies, but always compare piston diameter and shaft fitment to your shock internals before purchasing.

How often should I inspect or replace the piston?

Inspect pistons every few services for wear, scoring or deformation and replace if you notice excessive play or damaged holes to keep damping consistent.
