SwingAway has now combined Kevlar with a coated Nylon jacket to produce the Extreme Baseball Tune Up Kit. Our new Baseball Tune Up Kit comes with an upgraded Tether (cord that runs to the bottom corners of the frame) and ball rope (cord that runs through the baseball). This tune up kit is universal and will fit any SwingAway Hitting Trainer.
