COMP Cams Cam Button Adjust Buick V6 Hy

This .660" long roller bearing thrust button from COMP Cams is designed to control camshaft endplay on a range of Buick V6 engines from 1977.5 through 1987. It fits snugly between the front of the timing gear and the inside of the timing cover, effectively preventing the camshaft from moving backward and forward. This is often a necessary part when you're converting to a roller cam and lifter setup, ensuring everything stays properly aligned.

You can shim this thrust button as needed to achieve the precise camshaft endplay your engine requires. It's a well-built component that helps maintain proper timing gear alignment and prevents potential damage from excessive camshaft movement. For engines like the Buick Regal, Century, or even the Pontiac Firebird from the specified years, this button is a practical solution for managing thrust loads.
