Automotive Racing Products, Inc. (ARP) has recently expanded its head stud lineup to include a number of aftermarket applications. These include kits for the new Dart LS Next block (with 15 or 23-bolt cylinder heads), big block Chevy with Brodix SR20 heads, and RHS small block Chevy LS with RHS LS7 heads. New stud kits for OEM applications have also been released.

Many of the new kits for aftermarket engines are manufactured using ARP2000 material, a proprietary alloy that’s heat-treated in-house to a nominal tensile strength of 220,000 psi. The studs are centerless ground and thread- rolled after heat-treating—which adds substantially to their fatigue strength. They provide the extra clamping force required to maintain an optimum cylinder head seal in high combustion pressure environments. ARP is an NHRA Major Sponsor and posts contingency awards for head studs and head bolts.

The head stud kits come with precision parallel-ground washers and chrome moly nuts. A packet of ARP Ultra-Torque fastener lubricant is also included. All ARP fasteners are manufactured in-house to stringent AS9100 and ISO-9001 quality control standards.

A complete listing of all the new kits can be found at ARP-Bolts.com, and the new 2014 ARP catalog is available for downloading. Call 800-826-3045 for technical assistance.
