Product Description
The CUMMINS 3535001 OEM HX35 TURBO OUTLET GASKET is the correct 5-bolt downpipe flange gasket used on Holset HX35 turbochargers found on 1994–2002 5.9L Cummins 12-valve and early 24-valve engines. This genuine Cummins gasket creates a proper seal between the turbocharger discharge flange and the downpipe to prevent exhaust leaks, boost loss, and unwanted soot buildup.
If you are installing a new HX35, resealing an old unit, or replacing a leaking outlet flange gasket, the 3535001 Cummins turbo outlet gasket ensures factory-level fitment and heat resistance. Cheap aftermarket gaskets distort under heat, leading to leakage and backpressure problems. This genuine Cummins part maintains exhaust flow efficiency and protects against premature deterioration.

FAQ
WILL THIS 3535001 GASKET FIT MY HX35 TURBO?
Yes. If your 1994–2002 Dodge Ram 5.9L Cummins uses a Holset HX35 or HX35W turbo with a 5-bolt outlet flange, this gasket is the correct OEM replacement.
CAN THIS GASKET FIX AN EXHAUST LEAK AT THE DOWNPIPE FLANGE?
Yes—this gasket is specifically designed to seal the turbo outlet to the downpipe. If you notice soot streaks, noise, or boost loss, replacing the gasket typically solves the issue.
IS THIS A GENUINE CUMMINS PART?
Absolutely. This is a 100% genuine Cummins OEM 3535001 gasket, not a thin aftermarket copy. It is built to withstand extreme turbo temperatures.
WHAT OTHER GASKETS SHOULD I REPLACE WHILE SERVICING MY TURBO?
CPP Diesel recommends replacing nearby seals such as the 3932474 oil feed gasket and 3917707 oil return gasket to ensure proper sealing throughout the turbo system.
