Introducing Weistec's ARP Head Studs

Weistec has teamed up with ARP, a leader in performance engine hardware, to bring you a product that truly makes a difference. Our head studs replace the factory head bolts, providing a secure connection between the cylinder heads and the engine block. This connection is vital, as it allows coolant and oil to flow seamlessly while keeping everything in check.

Why Head Studs Matter

The head gasket plays a crucial role in maintaining the separation of coolant, oil, and air in the cylinders, relying on the pressure generated by the head bolts. Unlike the factory head bolts, which are "torque to yield" and stretch permanently when installed, Weistec's ARP head studs are designed for durability and reliability. They are especially beneficial for those looking to increase boost pressures and power levels in the already impressive M113K engine.

Unmatched Strength and Performance

With an impressive tensile strength of over 220,000 PSI, our ARP 2000 Head Studs can hold down the cylinder heads with significantly more pressure than the factory bolts, all without the risk of permanent stretching. This means you can enjoy a more dependable performance engine, free from leaks between the heads and block. Quality head studs are essential for achieving those high power levels you crave.

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design.
