BD9 HVF Shock Shaft 19.1mm - B9-S5SHVFA Yokomo  [B9-S5SHVFA]

High-performance HVF shaft for BD9 damping

The Yokomo B9-S5SHVFA HVF shock shaft is produced at 19.1mm and features a heavy fluorine coating to minimize surface friction and improve longevity. Designed with input from AXON, the shaft reduces bearing and seal drag to promote cleaner damper movement on BD9 chassis platforms.

When tuning, the reduced stick-slip behaviour at the sliding interface helps the shock register subtle inputs consistently, which supports better traction and more predictable handling through setup changes. Internal testing highlighted noticeable wear improvements over older finishes.

This HVF shaft targets BD9 racers and tuners who want lower damping friction and consistent shock action for competitive 1/10 touring car setups.
