Fine Tune Vintage XB Shocks with Precision Pistons

The XRAY 358037 4-Hole Composite Shock Piston Set is produced with tight tolerances to maintain roundness and smooth travel inside classic XB shock absorbers. This attention to detail reduces binding and helps the shock respond more predictably across varied track surfaces.

Increased Flow for More Tunability

Featuring four straight holes in 1.3mm, 1.4mm and 1.5mm sizes, these pistons move oil more freely than two-hole types. That extra flow makes it practical to use heavier shock oils and broaden your damping setup for different handling preferences.

Who Should Fit These Pistons

These wide pistons suit older XRAY XB models and are a straightforward option when refreshing vintage cars or improving on-track balance. They work without changing the stock shock stroke or mounting points.
Remark :
Due to limited stock availability, please notice that some XRAY 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 compatible with modern XB shocks?

They are designed for older XB shock housings; newer shock designs may use different bore sizes, so confirm fit before purchase.

Will they change ride height or spring rate?

No, the pistons alter damping characteristics only; ride height and spring rate remain set by springs and shock length.

Best practice when swapping pistons?

Clean the shock internals, check seals and bushings, and bleed air carefully after fitting a new piston to ensure consistent damping.
