Optimise BD9 performance with Yokomo B9-SSP245A

The Yokomo B9-SSP245A Progressive Shock Spring is a graduated-rate coil aimed at improving BD9 shock behaviour. Produced in cooperation with AXON, the unequal pitch profile helps control body roll and enhances traction under load. Its 2.45 to 2.75 spring rate offers tuners a useful spectrum to tailor handling for different circuits and tyre compounds.

Feature Summary

  • Compatibility: Intended for BD9 chassis and other compatible setups.
  • Spring Rate: 2.45 to 2.75 for stepped stiffness through travel.
  • Design: Unequal coil spacing to give progressive support.
  • Collaboration: Created with AXON for a race-oriented build.
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.

Which shock types are these springs made for?

They are designed for high big bore short shocks commonly fitted to BD9 cars; measure your shock length and shaft diameter to confirm fit.

Will these springs change turn-in or corner exit?

Expect improved midstroke support which can stabilise corner entry and give a more consistent exit as the spring firms up under load.

Are they ready to use out of the pack?

Yes, they are ready to install, but fine tuning with preload and shock oil adjustments is recommended to match your setup and track conditions.

How do I maintain progressive springs?

Keep them clean and inspect for wear or nicks on the coils; replace if the spring becomes bent or loses consistent action.
