FAQ
Will this fit both 5.9L and 6.7L Cummins?Yes—this stud is listed for 1989–2018 Dodge Ram Cummins 5.9L and 6.7L applications. Always confirm against your ESN or existing hardware before installation.
Is it sold individually or as a kit?
Sold individually. Order the number of studs you need for your turbo/manifold flange. Many setups use four positions; confirm your manifold and turbo flange requirements.
What nut should I pair with this stud?
Use the matching M10 × 1.5 flange nut, OEM cross-ref 3818824 (Interstate-McBee M-3818824). Replacing nuts along with studs is recommended due to heat-cycle fatigue.
Do you provide torque specs?
