# Hammer Aggressive Reaction Technology (HART) - Hammer is very pleased to introduce the new Hammer Aggressive Reaction Technology (HART) core concept to the bowling industry. Developed by our team of design engineers, this radical new concept in bowling ball core design provides maximum performance without the need for exotic layouts and weight holes. It is that simple.
Combining the new HART core concept and Violent Response Reactive coverstock gives the bowlermore aggressive hook motion and improved hitting power. This unique coe concept delivers aggressive backend reaction by placing the pin at 1:30 with the HART in the track (see Drilling #1).
