ARP Head Stud Kit, Ford Coyote 5.0L, 2011-12 only (M12)

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 (5mm broached hex); flanged nuts with 12-point heads (14mm wrenching); hardened, parallel-ground washers; and a packet of ARP assembly lubricant. Fits the 5.0L Ford "Coyote" V8 engine from 2011-12 only (2013 and later eginess require different studs with M11 threads).
