High Precision Progressive Spring from Yokomo

The Yokomo B9-SSP250A Progressive Shock Spring is aimed at hobbyists seeking refined handling. Produced in collaboration with AXON, the spring uses an unequal pitch tailored for high big bore short shocks and offers a tuning span of 2.40 to 2.70 to help you tune traction and mid-corner support.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 this on older BD series cars?

In many cases yes. The B9-SSP250A is compatible with a variety of BD-series cars, including models like MRTC-BD919, MRTC-BD10 and MSR-BD12, provided the shock mounts and length suit the chassis.

What is the practical advantage of a progressive spring?

Progressive springs provide gradual increase in stiffness under compression, which helps maintain grip on initial travel while preventing bottoming under heavy loads for more predictable handling.

How should I start tuning with this spring?

Begin with a baseline shock oil and standard piston, then alter preload and oil weight to match your driving style; small increments in preload will reveal the spring's progressive behaviour.
