A high-quality aftermarket sleeve adapter which changes the loft (+/-) 2.0 degrees to optimize the trajectory for each golfer's unique swing. Right Hand markings (still works with LH heads but markings are opposite) Including ferrule, washer and screw, fitting .335 tip size shafts. Always use the appropriate wrench (torque) to tight the screw to avoid damage to the sleeve and club head. Please do not use Acetone to clean it, as the markings maybe removed. It's recommended to use Isopropyl Alcohol instead to clean epoxy after installing.
