Essential for high compression or boosted EG33 builds!
Includes 16 studs,16 12 pt nuts,16 hardened washers
These studs are constructed out of grade ARP2000 alloy that is rated far superior to “aircraft” quality. Then each stud is placed vertically In special racks and precisely heat-treated to 220,000 PSI. These studs are then rolled after the heat treatment, and this gives them about 1000% better fatigue resistance than your standard head studs.
ARP's Custom Age 625 Plus material is newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength (260,000 psi) and toughness - with complete resistance to atmospheric corrosion and oxidation. Excellent choice for high hp/ high cylinder pressures while retaining a factory sized fastener.
Each set is built to order, allow 7-10 days to ship.
