ARP SR20 Head Stud Kit

Automotive Racing Products (ARP) are the leading brand in fastener technology. All fasteners are made with the highest quality materials with quality assurance testing.

ARP manufactures fasteners from a wide assortment of materials ranging from popular stainless steel and 8740 chrome moly to exotic alloys that have been developed to handle space travel.

The ARP SR20 Head Stud Kit is available in premium grade 8740 chrome moly and includes hardened parallel washers for an even load distribution and accurate torque readings.

8740 Chrome Moly: Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.

CA625+: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260,000-280,000 psi.

The CA625+ kit is a special order with an approximate lead time of 2 – 5 days. This kit is a customized kit including a set of 10 head studs, 10 parallel ground washers, ten 8740  nuts and fastener assembly lubricant. This kit utilises all genuine ARP products featuring Dog Point bottoms. A Dog Point is a straight pointed section, reduced in diameter slightly below the root diameter of the thread. It usually extends in length about two-thirds the diameter of the thread. This aids component assembly, seats studs in the block, and preloads the fastener for accurate, repeatable torque sequencing.
