Race Grade Shaft Cushioning

The 3Racing Sakura Ultimate 4mm Universal Shaft Cushion (SAK-U122D) is intended to provide consistent axial support for 4mm drive shafts in Sakura Ultimate chassis. Its role is to maintain alignment under load and reduce lateral play that can compromise drivetrain response.

Fitment for Competitive Setups

Engineered to match Sakura Ultimate geometry, the cushion ensures predictable shaft seating and repeatable clearance for precise tuning. It is useful when refining driveline feel during setup work.

Durability Focused for Tuning Use

Manufactured to withstand frequent teardown and rebuild cycles, the 3Racing cushion offers stable behaviour across repeated testing. Use it as part of a systematic setup process to evaluate other tuning changes.
