ARP Head Stud Kit, Ford Coyote 5.0L, 2013 and later (M11)

Brand: Automotive Racing Products (ARP)

High-performance ARP Head Studs are rated to 200,000 psi for exceptional strength in the most demanding applications. Head studs offer more predictable fastener torque and more even gasket clamping force than bolts, which is why serious engine builders never use cylinder bolts if the installation will allow it.

This kit includes a full engine set of 20 studs (M11 block thread, 7/16" nut thread with a 3/16" broached hex); flanged nuts with 12-point heads (5/8" wrenching); hardened, parallel-ground washers; and a packet of ARP assembly lubricant. Fits the 2013 and later 5.0L Ford "Coyote" V8 engine (2011-12 eginess require different studs with M12 threads).
