About this part

Product Details

This is the Turbosmart 74mm Diaphragm Replacement Kit, designed specifically for their Gen V UltraGate38 and Compgate40 external wastegates, whether they are the Standard or HP versions. If you're rebuilding or servicing your wastegate, this kit is what you need to ensure it operates as intended.

The diaphragm is a critical component in a wastegate, controlling the boost pressure by opening and closing the wastegate valve. Over time, or under demanding conditions, this rubber diaphragm can wear out or become damaged, leading to inconsistent boost control or even boost leaks. Replacing it with a fresh, well-made diaphragm from Turbosmart will restore proper function and help maintain consistent boost levels.

This kit includes the necessary diaphragm for a complete service of your compatible Gen V wastegate. Always refer to the manufacturer's installation instructions for the correct procedure when servicing your wastegate.
