ARP 204-4204 Head Studs for VW Golf/Jetta 1.8 16V (M11)

Brand: ARP
Part number: ARP-204-4204
Country of manufacture: United States

ARP Pro Series head studs are widely used by professional engine builders for competition engines where consistent head clamping matters. Compared to head bolts, studs simplify assembly by helping the head and gasket align cleanly, and they improve torque consistency because the stud stretches primarily on the vertical axis while the nut is torqued.

Construction & Manufacturing

Manufactured from premium grade 8740 alloy and ARP’s proprietary ARP2000 alloy.
Heat-treated with studs positioned vertically for full heat penetration.
Rated to 190,000 psi (8740) and 220,000 psi (ARP2000).
Made to tight tolerances for precise fit and alignment of the cylinder head and gasket.

Why Use Head Studs

Easier engine assembly and service, especially on engines that are frequently torn down.
More accurate, consistent torque loading than head bolts.
Even clamping force across the cylinder head.

Installation Note

Install studs in a relaxed mode—hand tight. Do not crank them in using a jammed nut. Torque is applied to the nut, allowing the stud to stretch correctly.
