Scorpion Racing Products 7/16" Polylock

A Polylock is an adjustable rocker arm nut. They are used with Stud Mount Rocker Arms.

How do they work?

A polylock features a threaded body and a set screw.

An Example of a Polylock

The body screws over the stud and holds the rocker arm in place. Then, the set screw is tightened down against the stud. This locks the body in place.

Why would I need them?

Polylocks make adjusting you valvetrain much easier. They are useful when Setting Preload on hydraulic lifters. They are required to Set Valve Lash on solid lifters.

Polylocks also come in various lengths. The longer body sticks up above the rockers to attach a Stud Girdle

Watch as Scorpion’s Design Engineer shows you how to set valve lash.
