Service Under Head for KE25SP Engines

The Kyosho 74032-02 under head is a dedicated spare for the KE25SP engine, intended to maintain the seal between cylinder and head. Proper sealing keeps compression steady and helps the engine run cleanly over time.

Compatibility Notes

This under head fits the KE25SP as a direct replacement and is manufactured to match the engine's mating surfaces. It is suitable for routine use and for modelers who need a straightforward spare part that preserves engine integrity.

Practical Installation Steps

Installation requires basic care rather than specialist tools. Clean the contact areas before installation and tighten fasteners evenly to avoid misalignment. Replace the under head if you detect persistent leaks or loss of performance.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

Does this under head need machining before use?

No machining is normally required if the part is fitted to a standard KE25SP. Check surfaces for flatness and clean them before installation.

Will this part improve a weeping head joint?

Replacing a damaged or worn under head can stop leaks at the cylinder-to-head joint, provided the mating surfaces and bolts are in good condition.

Are there upgrade options for better sealing?

Some tuners use new gasket materials or carefully prepared mating surfaces to improve sealing, but always follow engine builder guidance to avoid unintended changes.
