ARP – Head Stud Kit 12-point – Subaru EJ20/EJ25

Description

Upgrade your competition powerplants with ARP Pro Series head studs, the preferred choice of top professional engine builders for unbeatable performance. Crafted from a premium grade 8740 alloy, surpassing aircraft quality standards, each stud undergoes precise vertical placement in special racks and heat treatment to 200,000 psi. This meticulous process ensures superior heat penetration, setting ARP head studs apart from lesser quality alternatives. Unlike competitors who take shortcuts, ARP’s commitment to excellence includes specially undercut studs for select engines. This exclusive procedure equalizes stud stretch, providing a consistent clamping force that compensates for head gasket compression during cylinder installation. Say goodbye to blown head gaskets and ensure optimal sealing. ARP head stud kits offer versatility with a choice of conventional hex nuts or compact 12-point nuts. Elevate your engine’s potential with our premium quality ground Application List, featuring compatibility with Subaru EJ20 and Subaru EJ25. Trust ARP for unrivaled quality in head stud technology.
