Designed specifically for the hybrid and plug in hybrid vehicles from Hyundai and Kia. The Laser 8942 locks into the back of the flywheel/drive plate from underneath the vehicle. The flywheel/drive plate on the vehicles listed do not have a ring gear so the 8942 specially shaped pawl is designed to lock into the back of the drive plate to lock the engine and allow removal and e-torquing of the crankshaft pulley.
