Tweak BD9 handling with Yokomo B9-SSP245A

The Yokomo B9-SSP245A Progressive Shock Spring brings a variable-rate coil to your BD9 setup. Built in collaboration with AXON, the unequal pitch profile improves midstroke support and overall stability. With a spring rate spanning 2.45 to 2.75, it gives precise adjustment range for big bore short shocks so racers can fine tune balance and response on varied track surfaces.

Main Details

  • Compatibility: Fits BD9 chassis and closely related models.

  • Design: Unequal pitch coil to enhance traction and composure.
  • Collaboration: Co-developed with AXON for quality-focused design.
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.

Will this spring fit other Yokomo models?

Yes. It is compatible with several Yokomo models, for example MRTC-BD10 and MSR-BD12, where similar shock dimensions are used.

How does the unequal pitch affect cornering?

The unequal pitch increases midstroke support and helps manage weight transfer, which can improve front grip and stability through corners on uneven surfaces.

Any setup tips for BD9 with these springs?

Start with your usual shock oil and ride height, then adjust preload to tune initial bite; small changes to shock oil or mount position will alter feel more than large spring swaps.
