High-Precision Shock Cylinders for BD12

The Yokomo B12-S4S aluminium shock cylinder is engineered to bring greater longevity and steadier damping to the BD12 chassis. Precision machining yields tighter tolerances which help sustain consistent shock performance across sessions.

Improved Handling and Shock Consistency

The B12-S4S offers reduced internal stiction to support more predictable rebound and compression tuning on the BD12. Its aluminium construction helps preserve shock geometry under repeated track use, aiding drivers who focus on setup consistency.
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 cylinders serviceable?

Yes, they can be disassembled for cleaning and seal replacement; regular service will help maintain smooth damping and prevent leaks.

Which piston choices work best?

Standard BD12 piston options are compatible; select piston hole patterns and oil weight to tune compression and rebound for the circuit you run.

What maintenance should I do after a race?

After a race inspect seals and shafts for wear, clean out old oil and refill with the appropriate viscosity to keep shock performance consistent.
