Scorpion Performance Poly Lock pack Of Engine Rocker Arm Nut

Scorpion Performance Poly Lock rocker arm nuts are adjustable polylock-style nuts for stud-mounted rocker arms. They are made for high-performance street and racing valvetrain setups. Each nut has a threaded body and a set screw, so you can adjust the valvetrain and lock the setting in place. They are also sold as polylocks, poly locks or adjustable rocker nuts.

Key Features:

• Adjustable polylock design: The body threads onto the rocker stud, and the set screw tightens against the stud to lock the adjustment.
• Valvetrain adjustment: Makes it easier to set preload on hydraulic lifters. It is also needed to set valve lash with solid lifters.
• Hardened steel construction: Machined from 4140 steel for strength under high-performance loads.
• Black oxide finish: Protects the surface of the nut.
• American-made quality: Scorpion Racing Products is a U.S. manufacturer of valvetrain components for street and racing use.

Polylocks work with stud-mount rocker arms. They are a dependable replacement or upgrade for engine builders and enthusiasts who want accurate, repeatable valvetrain adjustment.
