How to Install ARP Main Stud Kit (96-01 Cobra) on your Ford Mustang

1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase the threads if necessary with ARP Thread Chaser, part number 912-0003 (M10 X 1.5) and 912-0001(M8 X 1.25).

2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length and dimension.

3. Screw the studs into the block “HAND TIGHT ONLY”. NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED. THE FASTENERS, HOWEVER, MUST BE TORQUED PRIOR TO THE LOCTITE SETTING UP.

4. Install the main caps and check for binding or misalignment.

5. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Then install the washers and the nuts onto the studs and tighten them hand tight. 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 other low quality lubricants are used.

PRELOAD (TORQUE) RECOMMENDATIONS

6. 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.

M10 studs 60 ft lbs       M8 studs 25 ft lbs

FOOTNOTE: When changing from factory fasteners to high strength fasteners, clamping force and tolerances will change, therefore it will be necessary to check the main bearing bores for proper size and out of round condition after installation of the studs and align hone the cylinder block if necessary. The main bores should always be align honed using the same fasteners and lubricant which will be installed during final engine assembly at the recommended preload.

1. When using the OEM oil pan and pick up tube it will be necessary to shorten the oil pick up pedestal by .070 in. to set the oil pick up tube back at the stock height.

2. When using aftermarket oil pans and pick ups follow the oil pan manufacturers recommendations for oil pick up tube installed height. Typically most aftermarket oil pick ups are installed .0250 in. - .375 in. above the inside floor of the oil pan.
