Dial in your BD9 with Yokomo B9-SSP245A

The Yokomo B9-SSP245A Progressive Shock Spring adds a graduated rate to BD9 dampers for better midstroke control. Created alongside AXON, its unequal pitch construction aims to stabilise chassis movement while still allowing initial compliance. The 2.45 to 2.75 range provides a practical tuning band for high big bore short shocks used in competitive touring setups.

Highlights

Compatibility: Made for BD9 platforms and similar shock configurations.
Spring Rate: 2.45 to 2.75 to offer subtle to firm progression.
Design: Uneven coil spacing to improve balance and traction.
Collaboration: Developed with AXON to meet racing expectations.

Can I fit these springs to non-BD9 cars?

You can fit them to other cars with compatible shock shafts and stroke, but check dimensions first; commonly used Yokomo examples include MRTC-BD10 and MSR-BD12.

What does the 2.45 to 2.75 range mean in practice?

It means the spring gets firmer through its travel, giving a softer initial feel with stronger support as the damper compresses, useful for tuning midstroke response.

Should I change shock oil when fitting these springs?

Often a small oil weight tweak helps balance rebound with the progressive rate; try a slightly heavier oil if the car feels too soft midstroke.
