STUDS vs. BOLTS

Virtually every top professional engine builder relies on ARP head studs for their all-out competition powerplants, and for good reason!

Here’s why: when you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously.

Studs also provide more accurate and consistent torque loading. Using studs ensures easier engine assembly, and proper alignment of both the cylinder head and gasket.

Install a stud in a “relaxed” mode – never crank it in tightly using a jammed nut. Always install the stud hand tight! Then, when applying torque to the nut, the stud will stretch only on the vertical axis.
