Suspension Upgrade with Kyosho Big Bore Springs

Built for the Ultima SB Dirt Master, the Kyosho W5309-36 Big Bore Spring set improves suspension tuning to give more predictable handling on rough trails. These springs are manufactured to help you dial in balance and control when running off-road.

Design and Fit

The Kyosho W5309-36 springs deliver a balanced response suited to high speed off-road work. With a length of 44mm and a wire diameter of 3.55mm, they strike a practical mix of toughness and compliance for hobbyists aiming for firmer damping and better stability.
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 springs fit other Kyosho models or kits?

They are specified for the Ultima SB Dirt Master but can fit other Kyosho cars that accept 44mm long springs with a 3.55mm wire. Check your shock shaft and spring cup dimensions before fitting.

How should I adjust damping after installing these springs?

Start with stock shock oil and a small preload change, then increase oil weight or add spacers to slow rebound if the car feels too bouncy. Test on the terrain you run most.

Are these springs good for mixed surfaces and rough tracks?

Yes, the W5309-36 springs are designed to handle uneven ground and jumps while keeping stability. Pair them with appropriate shock setup to suit loose, rocky, or packed surfaces.
