ARP 275-4701 Head Stud Kit, Lancia Delta Integrale 2.0L 16V

Description

The ARP 275-4701 head stud kit is made for Lancia Delta Integrale 2.0L 16V engines.

Head studs clamp the cylinder head more evenly and more accurately than head bolts. A stud is threaded into the block once and stays put, so torque applied to the nut goes into stretching the stud and not into twisting it. That gives a more consistent clamp load across the head gasket, which matters most on boosted, high-compression, and race engines.

ARP head studs are heat-treated before the threads are rolled, which gives far better fatigue strength than threads cut or rolled before heat treatment. Each stud is centerless ground for concentricity.
