Improve RC Suspension with Kyosho IFW405-138

The Kyosho IFW405-138 pistons are made to refine your vehicle's shock response. Matching larger damper bodies, the pistons use a deliberate hole pattern to moderate oil flow and enhance stability under diverse driving loads.

Performance Across Different Conditions

The diagonal hole configuration gives a calm, controllable feel in normal running while increasing damping force during severe compression. This provides better control on landings and helps prevent hard bottom-outs that unsettle the chassis.

Fitment Notes and Setup Guidance

These pistons are a practical upgrade for anyone using big dampers who wants clearer midstroke control and stronger endstroke damping. Experiment with oil grades and spring choices to suit your vehicle and surface.
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 do I know if IFW405-138 suits my shocks?

Measure your shock internal bore and check piston retainer compatibility; if dimensions match Kyosho big damper standards, these pistons are a suitable fit.

Will these pistons help on high speed tracks?

Yes, they can stabilise rebound and compression at speed, reducing unsettled reactions over jumps and uneven sections when tuned correctly.

Can I mix these with aftermarket shock parts?

They are compatible with many aftermarket big shock setups, but confirm piston retention and shaft clearance before mixing parts to avoid binding or leaks.
