Fine Tune the Ultima RB7 with Kyosho W5303-13 Pistons

RC hobbyists wanting sharper suspension response for the Ultima RB7 will find the Kyosho W5303-13 pistons a practical upgrade. These 1.7mm 2-hole pistons are built to stabilise oil flow in big bore shocks, helping produce more predictable handling through corners.

Controlled Damping for Track Use

The Kyosho W5303-13 pistons give better metering of shock oil so your big bore shocks react more consistently. The two-hole layout balances flow for steady compression and rebound without unpredictable stick-slip behaviour.

Direct Fit for Ultima RB7 Chassis

Designed to suit the Ultima RB7, these pistons slip into compatible big bore shock assemblies with minimal fuss. Swapping to these pistons can help reduce body roll and improve mid-corner stability when dialling in your setup.

Practical Installation and Care

When fitting Kyosho W5303-13 pistons, match shock oil viscosity to driving conditions and check seals for wear. Regular inspection and oil changes will keep damping consistent and extend the life of the piston and shock internals.
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 these pistons change shock feel on the track?

They refine oil flow through the damper body so compression and rebound feel smoother and more consistent, which helps drivers predict handling through repeated laps.

What shock oil viscosity should I try first?

Start with a mid-range silicone oil recommended for big bore shocks and adjust heavier or lighter based on whether you need slower or quicker rebound and compression.

Any tips for piston maintenance?

Inspect pistons and shock shafts for scoring, keep seals clean, and replace oil regularly to prevent abrasive wear and maintain damping precision.
