GFB-6182 Replacement Diaphragm Assembly

🔧 Product Description

The GFB-6182 Replacement Diaphragm Assembly is a genuine service component designed for Go Fast Bits EX38 and EX44 external wastegates. This diaphragm is a critical internal part responsible for controlling boost pressure via the wastegate actuator.

Over time, diaphragms can wear, harden, or fail due to extreme heat and pressure. Replacing it restores accurate boost control, reliability, and performance.

According to GFB, this assembly is a direct replacement for wastegates part numbers 7002 (EX44) and 7003 (EX38)

⚙️ Key Features
