Collection: ARP Main Stud Kits

Browse ARP main stud kits and compare individual listings for engine fitment, main-cap configuration and part number.

Match the kit to your engine

Check the exact engine family, block version and main-cap arrangement against the ARP application details. Review any sump or oil-pan restrictions, stud lengths, nut style and clearance requirements. Engine capacity or brand alone does not establish fitment.

Compare each kit's listed contents, material and strength specification rather than assuming the same specification applies across the range.

Plan installation with your engine builder

Follow ARP's instructions for the exact kit, including thread preparation, specified lubricant, tightening sequence and torque values. Have your engine builder assess main-bearing housing alignment, bearing clearances and any machining requirements as part of the installation.
