The TANK M1 Elevated Tow Bar Retro Kit will allow you to take your first-generation TANK M1 to the next level by expanding your training options with the improved 3-Position Tow Bar. This allows you to attach the optional Dumbbell Cradles for added traction and functionality for training on the go. The step-by-step instructions and video will walk you through replacing the push/pull bar, the bumper, and installing the new label.
