For QI35 MAX: Custom-made for the TaylorMade QI35 MAX driver, featuring precise M4 x 0.7mm threads for a perfect fit into the original weight holes, maintaining the integrity of the original clubhead, consistent clubface alignment, and consistent ball speed throughout the set.Tournament-grade tungsten weights: Utilizing premium high-density 8g and 10g aluminum cores with a tolerance of ±0.2g, allowing for fine-tuning of launch angle and feel; front weights reduce backspin by up to 300 RPM for a more penetrating trajectory; rear weights increase MOI by approximately 15%, providing greater forgiveness.Tool-free, easy 30-second replacement: Reinforced T9 screw interfaces are compatible with standard torque wrenches, making it easy to change weights during swings or practice breaks; the shock-absorbing groove design prevents loosening even at swing speeds above 110 mph, eliminating the need for adhesives or professional fittings.Adjustable D0-D6 swing weight range: Adjust clubhead feel according to your shaft, grip, and hitting rhythm to optimize distance control and dispersion; subtle changes in clubhead weight promote a smoother backswing transition, more consistent shots, and greater confidence in shot control from the tee to the fairway.Color: BlackMaterial: AluminiumPackage Contents:2 * golf ball accessoriesOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
