Precision tuning for BD9 with Yokomo B9-SSP245A

The Yokomo B9-SSP245A Progressive Shock Spring brings a stepped coil rate to BD9 dampers to aid balance and traction. Developed with AXON, its unequal pitch layout is aimed at delivering firmer support deeper into the stroke while retaining initial compliance. The 2.45 to 2.75 rate span gives a controllable range for competitive setups using big bore short shocks.

Product Benefits

  • Compatibility: Suits BD9 chassis and other systems that share the same shock dimensions.
  • Spring Rate: 2.45 to 2.75 to allow progressive stiffening.
  • Design: Unequal pitch to improve stability and tyre contact.
  • Collaboration: Developed in partnership with AXON for performance focus.
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.

Are these springs compatible with other Yokomo shock sets?

They are compatible where shock bore, shaft and travel match BD9 dimensions; common examples include models like MRTC-BD10 and MSR-BD12.

What race conditions suit progressive springs?

Progressive springs work well on tracks with mixed corners and bumps, where extra midstroke support helps maintain grip under load.

How should I pair these with shock oil?

Start with your standard oil and adjust one step heavier if the car feels too soft midstroke; small changes to oil weight and preload will refine the effect.
