Product Description
CUMMINS 3927811 OEM EXHAUST OUTLET ELBOW (HX35) – RAM 5.9L (1994–2002)
The genuine CUMMINS 3927811 exhaust outlet elbow is the factory-correct cast iron elbow used on HX35 turbochargers found on 1994–2002 Ram 5.9L Cummins applications. This critical component provides the proper sealing surface between the turbocharger and the downpipe, ensuring correct exhaust flow, turbocharger performance, and long-term reliability. Many failures originate from cracked aftermarket elbows or warped flanges—this OEM unit restores the durability and fitment your truck originally came with.
Whether you are replacing an HX35, installing a new exhaust system, or refreshing a high-mileage 5.9L, this OEM Cummins elbow eliminates exhaust leaks, protects turbo spool characteristics, and ensures OE-level durability. Pair it with a genuine turbo oil system refresh using parts such as the CUMMINS 3912747 turbo oil feed line and the CUMMINS 3286499 turbo oil drain hose for a complete factory-grade service job.
