Refine Suspension Response with Kyosho IFW405-138

The Kyosho IFW405-138 shock pistons are engineered to refine the suspension behaviour of your RC vehicle. Made for larger damper bodies, these pistons use a specific hole layout to balance smooth rebound with firm support on heavy compressions.

Controlled Damping in Daily Running and Jumps

The diagonal hole pattern on these pistons gives a two-stage response: predictable, steady damping during normal driving and increased resistance when the suspension compresses hard. That helps reduce bottoming out after big landings while keeping handling stable on corner exits.

Compatibility and Setup Advice

Hobbyists can fit the Kyosho IFW405-138 into many big damper setups to fine-tune ride feel. Pair them with appropriate shock oil and spring rates to match your vehicle weight and track conditions for best results.
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.

Will these pistons fit my existing big shocks?

Check internal shock bore diameter and piston mounting style; the IFW405-138 is made for most Kyosho big damper types but matching bore and retainer size is required.

Which shock oil should I use with these pistons?

Oil choice depends on vehicle weight and driving surface; start with a medium weight and adjust thicker for firmer rebound or thinner for quicker action.

Any tips for installation to avoid leaks?

Clean mating surfaces, use fresh o-rings, and bleed air carefully when assembling to ensure consistent damping and prevent oil weep.
