Nissan L24 L26 L28 Series 6-cylinder ARP Main Stud
Nissan L24 L26 L28 Series 6-cylinder ARP Main Stud is a high-strength ARP main-stud kit designed to improve main-cap clamping on the listed Audi engine.
Studs provide more repeatable fastener stretch and clamping load than factory torque-to-yield bolts, helping stabilise the main caps in high-output and high-RPM builds.
Installation and fitment: Main housing alignment and bearing clearance must be checked after fitting. Line honing may be required whenever the main fastener type or clamping load is changed. Use ARP lubricant and the supplied torque procedure.
Please confirm the exact engine code and required size against part number 202-5406 before ordering.
