Upgrade Big Bore Shocks with Kyosho W5303-06

The Kyosho W5303-06 shock pistons are tuned to enhance the performance of big bore shock systems. Their 5-hole configuration gives greater control over oil flow, helping you refine how the car soaks bumps and recovers off jumps.

How the 5-Hole Design Affects Damping

Each hole contributes to smoother fluid exchange inside the shock, reducing spikey reactions and improving consistency over varied surfaces. The design supports fine adjustments when changing oil weight or piston stacking for different track surfaces.

Durability and Fitment Considerations

Made to withstand repeated rebuilds, these pistons maintain shape and hole integrity under normal racing conditions. Confirm piston diameter and hole pattern fit with your shock cartridges to ensure correct installation and optimum performance.
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.

Can I use these pistons for both rear and front shocks?

Yes, you can use the Kyosho W5303-06 front or rear provided the piston diameter and shaft clearance match your shock bodies.

Will switching to 5-hole pistons change spring rates?

The pistons do not alter spring rate, but they change how the shock damps. You may want to retune springs to balance the new damping feel.

Are special tools needed to install these pistons?

Basic shock rebuild tools and a steady hand are sufficient. A small pick and proper shock oil will make installation and bleeding easier.

How do I test piston setup after installation?

Reassemble shocks and test on a controlled run, noting response to bumps, landings, and corner entry. Adjust oil or piston stack for desired control.
