This is a genuine Penske Racing Shocks PB-55 piston band, a small but critical part for anyone rebuilding or tuning Penske shocks.

It's a 55mm band, designed for linear high flow and digressive VDP applications.

Made from PTFE, it's built to reduce friction and keep the shock performing at its best.

It fits a ton of Penske series, including the 7100, 7150, 7300, 7500, 7600, 7700, 8300, and 8700.

This band is new, made in the USA, and sold individually.

No warranty, but it's a genuine Penske part—so you know it's the right spec.

If you're dialing in your suspension, this is the kind of precision piece you need.
