Tune Your Ultima RB7 with Kyosho W5303-13 1.7mm Pistons

For model racers aiming for steadier chassis behaviour, the Kyosho W5303-13 shock pistons offer a straightforward tuning path. The 1.7mm two-port design refines fluid movement inside big bore shocks to give a more controlled ride.

Steady Oil Flow for Predictable Handling

These Kyosho W5303-13 pistons moderate oil flow to reduce sudden damping shifts, helping the car stay composed on uneven track sections. The two-hole arrangement provides a stable balance between compression and rebound responses.

Made to Match Ultima RB7 Shock Geometry

They are engineered to fit the Ultima RB7 shock assemblies directly, so fitment is quick and exact. Racers can use them to tighten turn-in and improve exit traction by tuning spring and oil combination.

Installation Notes and Longevity

When installing Kyosho W5303-13 pistons, ensure you bleed the shocks of air and use a compatible silicone oil. Routine checks for wear and proper seal seating will help keep performance repeatable.
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 in other big bore shocks?

They may fit other shocks with similar piston dimensions, but confirm internal diameter and mount style before swapping to ensure correct operation.

How do I check the piston for wear?

Inspect the piston skirt and port edges for scoring or deformation and check for oil leaks around seals, replacing the piston if you notice uneven wear patterns.

Are there tuning tricks for different surfaces?

Use slightly thicker oil on high-speed or hardpack tracks for more stability, and lighter oil on loose surfaces to keep the suspension active and responsive.
