Upgrade YD-2 and YD-4 Dampers with Yokomo Y4-8BA

For RC builders aiming to tighten up their YD-2 or YD-4 setups, the Yokomo Y4-8BA 13.5mm Shock Cap Ball Set is a practical upgrade. This four-piece aluminium set boosts durability so your dampers keep moving freely even when cap nuts are snugged down.

Durable Aluminium for Secure Installation

These cap balls are machined to resist being crushed during damper assembly. Using aluminium gives extra strength without restricting pivot movement, helping maintain consistent shock action whether you are on the track or testing setups in the pit.

Made to Fit YD-2 and YD-4 Chassis

The Yokomo Y4-8BA cap balls are shaped for a precise fit on YD-2 and YD-4 shock assemblies. They are suitable for routine maintenance and for drivers who want a more robust alternative to softer stock parts.
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.

How does aluminium improve shock cap performance?

Aluminium resists deformation under tight nut torque, reducing the chance of crushed cap balls and keeping the damper shaft free to move for consistent damping.

Can I fit these to other Yokomo models?

These parts are optimised for YD-2 and YD-4 shock assemblies; while they may fit similar designs, they are specified for those chassis to ensure correct alignment and movement.

Any tips for installing the cap balls?

Install the ball, hand-tighten the nut then give a small final turn with a wrench. Check the shock moves freely after tightening and back off slightly if there is binding.
