FAQ
Q: Are these torque-to-yield bolts?
A: Yes. They are single-use; always replace after removal and follow the factory torque-angle procedure.
Q: How many bolts are in the kit?
A: 26 bolts — enough for one cylinder head.
Q: Stock or performance builds?
A: Ideal for stock to mild builds. For sustained high boost or big tunes, consider an ARP head stud kit.
Q: Do I need washers?
A: No. These bolts are designed to install without separate washers.
Q: Which head gasket pairs with this?
A: Use a new MAHLE head gasket matched to your year/engine (e.g., 54174 for 98.5–02; 54556/54557 for many 03–07 applications).
Note: Always verify by VIN/ESN and follow Cummins service procedures for torque sequence and angles.
