What is the difference between the Main Stud and a Head Stud?

The Main Stud is used for the installation of the Main Caps, The Main Caps hold your engine's crankshaft on the lower end of the motor.

The Head Stud is used for the installation of the Cylinder Head or Heads. The Head Stud holds the cylinder head in place on the engine block. The ARP Head Stud is what keeps the cylinder head in a constant state of tension to prevent head gasket failure. Heads studs work on the top of the motor.

  • FAQ: Do I need to install an ARP Main Stud Kit in my Polaris Razor Motor?
    These ARP main studs are designed to hold down the main bearing caps which secure the crankshaft in your engine block. The ARP main studs dramatically reduce the main cap walking and fretting. These ARP main stud kits are designed to keep the crankshaft securely locked in place within your motor. Using the proper fasteners to complete this job will help ensure a trouble-free life for your high performance engine. Why you should use ARP main studs over bolts? The ARP Main Studs provide more accurate torque readings because main studs do not twist into the engine block. The ARP Main Studs produce clamping forces that are on one axis. The ARP Polaris Main Stud Kit produces less force exerted on the block threads and contributes to improved engine block life. The use of the ARP precision-made main stud allows for easier engine assembly and provides Main Bolts to ensure the proper aliment of the main caps.
