Track-Focused Damping Upgrade for the BD7 2016

The Yokomo B7-S113A piston is made for the BD7 2016 short shock assembly and gives racers a precise 1.1mm bore with a three-hole layout. This piston improves the shock's metering for steadier rebound and compression, helping to stabilise your car through corners.

Performance Benefits of the 1.1mm Three-Hole Design

Built with competitive tuning in mind, the Yokomo B7-S113A balances oil flow and resistance to deliver more consistent damping. The three-hole pattern smooths midstroke response and can reduce unwanted chatter on high-grip surfaces.

Tuning Options and Setup Tips

This piston is a practical option when testing different shock oils and spring rates on the BD7 2016 short shock. Use it to dial in mid-corner feel and to explore small incremental setup changes that affect lap-to-lap 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.

Can I use this piston in other Yokomo shocks?

The B7-S113A is designed for the BD7 2016 short shock. It might fit other Yokomo short shocks, but you should verify internal dimensions before installing.

What shock oil weights work well with 1.1mm pistons?

Start with mid-range oils and compare results; the 1.1mm piston responds well to small changes, so try a range of viscosities to tune rebound and compression feel.

Any installation advice for avoiding leaks?

Inspect the shock shaft and seal for wear, apply a thin film of shock oil to seals during assembly, and torque fasteners evenly to prevent misalignment that can cause leaks.
