Description
Description
Lock down your head on the 5.9L / 6.7L Cummins 24V with the ARP 247-4202 Head Stud Kit. Studs thread into the block hand-tight and clamp down through the nuts, delivering consistent, high torque loading — this kit is torqued in three stages up to 125 ft-lbs for a serious, repeatable clamp on the cylinder head.
Why Choose the ARP Head Stud Kit?
- Stud Design – Studs thread into the block without applying torque, so clamping load comes through the nuts for more consistent, accurate torque than factory head bolts.
- High Clamping Load – Three-stage torque procedure to 125 ft-lbs for a strong, repeatable seal.
- Long Exhaust-Row Studs – Includes the longer 6.625" studs for the exhaust manifold side of the head.
- Install-Friendly – A hex broach in the end of each stud assists installation and removal from the block.
Installation Highlights
Clean and, if needed, chase all block threads before install (ARP Thread Chaser 912-0008, M12 x 1.75). Screw studs in hand-tight — do not torque the studs. Lubricate washers, stud threads, and nut bottoms with ARP Ultra-Torque assembly lubricant, then torque the nuts in three stages (40, then 80, then 125 ft-lbs) following ARP's torque sequence. Tools needed: 5mm Allen wrench and 14mm socket.

Notes
- Machining required: the lower rocker arm cover must be machined at the No. 24 bolt-hole location to clear the stud, nut, and washer. Remove material as needed so the head stud installs and removes easily.
- ARP Ultra-Torque Fastener Assembly Lubricant is required for correct torque readings.
- If chasing block threads, use ARP Thread Chaser 912-0008 (M12 x 1.75).
