• Replacement needs during cylinder head or valvetrain service
• Application matching for engines with listed camshaft requirements

Installation Notes and Tips

Verify the listed installed height, coil bind height, and pressure values before installation. Some fitments specify use with SPD-11, SPD-20, SPD-22, or SPD-25 camshafts, while others note exclusions such as do not use with rotators or except 4 barrel carburetor. Confirm the exact engine and application notes for your Chrysler, Dodge, or Plymouth vehicle before ordering the VS-150.
