Product Description
CUMMINS 3905216 OEM HX40 EXHAUST V-BAND CLAMP – RAM 5.9L / 6.7L (WITH HX40 TURBO)
The genuine CUMMINS 3905216 OEM HX40 exhaust V-band clamp secures the downpipe to the turbine outlet on HX40 and HX40-style turbochargers used in many performance and retrofit applications for 5.9L and 6.7L Cummins engines. This heavy-duty clamp provides the correct sealing pressure to keep the joint tight under heat cycles, high boost, and vibration—conditions where cheap aftermarket clamps often fail.
If your exhaust connection is leaking, rattling, or showing signs of clamp distortion, upgrading to a real Cummins OE clamp ensures proper fitment, stainless durability, and long-term reliability. Whether you’re installing a new turbo, replacing a worn clamp, or completing a performance build, CUMMINS 3905216 is the correct choice for HX40 turbine outlets.
