ARP SB Chevy Rocker Arm Stud Kit Pro Series, 1.900, 0.660 16 Piece 334-7201

If you have ever installed a rocker stud into a cylinder head and watched it wobble as it screwed in - you knew from the beginning that the rocker geometry was going to be inconsistent all over the place. ARP rocker studs are concentric within .005 T.I.R. thread pitch to thread pitch. They run-in straight and true.

Lengths are exact - designed to provide positive seating every time. An extra-large radius base offers greater resistance to flex. This is a Pro Series rocker stud.

Note: Not to be used with OEM-style, self-locking nuts. To be used with ARP's patented Perma-Loc adjusters (see page 88).

Important Tech Note: It is highly advisable to determine what the optimum rocker arm stud length is for your particular application. This is especially true when long pushrods and valves are employed - you should raise the installed height of the rocker arm to compensate for the longer-than-stock components.

Note: Fits most stock SBChevy with 7/16 screw-in studs.
