ARP 12-point head stud kit adds much needed strength to help keep your 5.0L Coyote engine from coming apart. Tech Note: Fits 2011-2017 blocks with deep head bolt threads. The 2013 blocks use external head bolt threads, also fits 2020 Shelby GT500
We suggested the ARP head stud kit for all Power Adder or Forced Induction applications, especially over 18lbs of boost.
ARP precision-machined head studs are heat-treated, centerless-ground, and thread-rolled to ensure consistent clamping force strength and durability. Only premium-grade 190,000 psi tensile strength 8740 alloy material is used, which is rated far superior to "aircraft" quality alloy steels. Head studs allow easy installation of both cylinder heads and gaskets, eliminating alignment guesswork. These kits come with 12-point head nuts.
