Fine Tune YD-2 and YD-4 Shocks with the Yokomo Y4-8BA

If you are refining chassis feel on a YD-2 or YD-4, the Yokomo Y4-8BA 13.5mm Shock Cap Ball Set provides a tougher alternative to soft caps. The quartet of aluminium balls helps ensure predictable damper movement under assembly loads.

Built to Resist Crushing

Soft cap balls can deform when nuts are tightened. These aluminium items are engineered to resist that deformation, so the damper internals retain smooth articulation and steady performance during runs.

Exact Fit for Popular Chassis

Yokomo designed the Y4-8BA caps to suit the geometry of YD-2 and YD-4 dampers, offering a straightforward replacement that fits without modification for routine servicing or race prep.
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.

Will these change shock travel or feel?

The main effect is improved durability; when fitted correctly the cap balls should not alter travel but can help preserve original damper action by preventing binding from crushed parts.

Are any special tools required to fit them?

No special tools are needed beyond basic shock assembly tools. A small spanner and careful hand-tightening are usually sufficient.

Do these replace the stock parts directly?

They are intended as direct replacements for the caps used on YD-2 and YD-4 shocks, offering a more durable option for maintenance or upgrades.
