At over 75% less weight than our closest competitor, the Tiger King Pin Press provides a much more effective, and user friendly design for ease of use, requiring only one technician to operate! Incorporating the use of a forcing screw, anti-torque arms prevent twisting of the main body while applying extreme forces via an impact wrench. The removal of King Pins can now be done in minutes with relative ease and efficiency. Designed for use on straight and tapered kingpins, and will accommodate sizes from 7/8" to 2 5/32" kingpins.
