FAQ
WILL THIS FIT MY 2003–2007 5.9L CUMMINS RAM?Yes—this clamp is for the HE341/HE351CW turbo center/bearing housing to turbine housing connection on 2003–2007 5.9L ISB Rams (verify by VIN/ESN and turbo tag).
IS THIS THE CENTER/BEARING HOUSING TO TURBINE CLAMP?Correct—this is not the downpipe/elbow clamp. For the elbow/downpipe connection on HE351, use clamp 3535399.
DOES IT INCLUDE THE NUT?No—the clamp is sold by itself. The matching nut is typically part number 3595659 (some catalogs list 4943908). Check your turbo hardware before ordering.
WILL THIS WORK WITH HE341 AND HE351CW?Yes—fits both HE341 (early ’03–’04) and HE351CW (’04.5–’07) center-to-turbine interface. Always confirm by part number and turbo model.
IS THIS A GENUINE CUMMINS PART?Yes—OE Cummins 3595658 for proper fit and durability.
