ARP\u00ae studs are thread rolled after heat-treat, which gives them about 1000% (that\u2019s ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it\u2019s tough on tooling, but the results are well worth the extra effort.
\nYou will also note that ARP\u00ae offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the \u201cstretch\u201d of both studs, which makes for a more consistent clamping force\u2014and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!<\/p>\n
Premium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import application. You won\u2019t find a better quality stud on the market from any other source. Look for ARP\u00ae stamped on each stud as your assurance of quality.<\/p>\n
ARP\u00ae head stud kits are available with your choice of conventional hex nuts or compact 12-point nuts. Premium quality parallel ground washers are also included with each kit. Clearly, they are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.<\/p>\n
