Koolnuts- The ONLY Locking Rocker Arm Adjuster that catches the oil 'squirt' from the rocker arm, and KEEPS it in the fulcrum where it belongs!

While you are here, scope out the nice (stock diameter) Valve Spring Package, good for up to .600 lift, with an awesome 140# @ 1.750! (Please don't tell me that you are running Z-28 springs!)
