The Yokomo B10-S3SA short shock spring cup is made for racers who want tight, repeatable suspension adjustments on BD9/10 chassis. This part helps hobbyists dial in ride height and spring preload while standing up to frequent track use.
Designed specifically for BD9/10 models, the Yokomo B10-S3SA offers a precise fit that promotes consistent shock travel and improved mid-corner stability. The secure seating reduces spring tilt and helps maintain predictable handling through a variety of cornering conditions.
The cup fits multiple chassis variants including MDR-020, SDR-020, and MDR-020BL, giving flexibility for racers with different builds. Installation is straightforward so you can swap the cups during a pit session without specialized tools.
