Dodge 5.9L 12V Cummins '94-'98 head stud kit
Applications
Cummins Diesel Passenger
Dodge Cummins Diesel
Material: ARP2000®
ARP2000®: An exclusive, hybrid-alloy developed to deliver superior strength and better fatigue properties. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.
Tensile strength: 220,000 psi
Yield strength: 180,000 psi

INSTALLATION METHOD FOR HEAD STUD KITS
Part Number: 247-4203 Application: Dodge 5.9L 12V Cummins Diesel
Note: This Head stud kit has been revised from its original version due to insufficient clearance
between the rocker arm pedestal and the bottom of the valve cover. Please read and note the following
changes before installation. Modification of the rocker arm pedestal (see illustration A on reverse side)
will be necessary to accommodate a shorter rocker arm pedestal head stud included in this kit. These
changes were designed to bring our 12pt nut and washer combination down to the same installed
height as the factory head bolt. We have also included in this kit the secondary 8mm rocker arm
pedestal (hold down) bolts which were previously not available.
1.
Always verify the part number for your application with the part number on the side of box and the
part number on the instruction sheet. This will help ensure you have the correct installation
procedure for your specific application before installing any components.
2.
To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block and the
threads in the cylinder head that secure the rocker arm pedestal to the head. Chase if necessary with ARP
Thread Chaser(s), part numbers 912-0008 (M12 x 1.75) and 912-0001 (M8 x 1.25).
3.
Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus
proper fit, length and dimension (see illustration B on reverse side).
4.
If the cylinder head studs protrude into a water jacket, lubricate the block threads of the studs with ARP
THREAD SEALER.
5.
Screw studs into the block “HAND TIGHT ONLY”.
NOTE: LOCTITE MAY BE USED IF PERMANENT MOUNTING OF THE STUD IS PREFERRED. THE
FASTENERS, HOWEVER, MUST BE TORQUED PRIOR TO THE LOCTITE SETTING UP.
6.
Install the cylinder heads and check for binding or misalignment.
7.
Install the pushrods.
8.
Install the rocker arms and the rocker arm pedestals onto the cylinder head as an assembly according to
OEM procedures. Make sure the dowel on the bottom of each pedestal is aligned properly with the
alignment holes in the cylinder head and the pedestals are sitting down flush on the head with the valve lash
adjusters completely backed off.
9.
Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY
LUBRICANT. ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY
LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on
the studs as well as inconsistencies in the clamping force of the fasteners when motor oil (or low
quality lubricant) is used. Also apply ARP Ultra-Torque Assembly Lubricant to the threads on the
secondary 8mm rocker arm pedestal (hold down) bolts.
10. Install the washers and the 12pt nuts onto the cylinder head studs and tighten them hand tight.
11. Install the secondary 8mm rocker arm pedestal (hold down) bolts into the cylinder head. Tighten the bolts
hand tight. Note: The secondary 8mm rocker arm pedestal (hold down) bolts must be installed in
place before tightening the head studs to properly align the tips of the rocker arms with the valve
stems.
PRELOAD (TORQUE) RECOMMENDATIONS
12. Following the manufacturers recommended torque sequence tighten the nuts in three equal steps
to the specifications listed below with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
M12 studs 125 ft lbs
M8 bolts 25 ft lbs
Note: ARP Ultra-Torque Fastener Assembly Lubricant has been specifically designed to reduce tension
preload scatter and eliminate the need to cycle high performance engine fasteners before final installation.
ARP Ultra-Torque far surpasses all requirements offered by previous ARP lubricants in terms of fastener
preload repeatability and performance lubricating properties. For more information on ARP Ultra-Torque visit
