COMP Cams Stud Girdle Adjusting Nut for Stud with Snap Ring

COMP Cams Stud Girdle Adjusting Nuts with Snap Ring are rocker arm adjusting nuts, also called polylocks or stud girdle nuts. They are made for valvetrain setups that use a rocker stud girdle. The nut secures the rocker arm and lets you adjust valve lash. The included snap ring holds the girdle bar in place on the nut.

Key Features:

• Precision ground: The nuts are ground for minimum runout, which helps keep rocker arm adjustment consistent.
• Tapered locking area: The taper adds strength where the nut locks.
• Built for strength and locking force: They keep the adjustment stable in demanding valvetrains.
• Snap ring design: The snap ring locates the stud girdle bar on the nut so the bar can't slide too far down it.
• Adjustable valvetrain: The nuts turn a positive-stop rocker arm setup into a fully adjustable one.
• Made in the USA: COMP Cams manufactures the nuts and backs them with a limited warranty.

A stud girdle bar reduces flex across the rocker system. It is not meant to stop the adjusting nut from turning. Install the nuts and set screws correctly so the adjustment holds. COMP Cams has been a leading maker of performance valvetrain components since 1976. These nuts are a good choice for performance and racing engine builds that use a stud girdle.
