The Simple Spring Locking System (SSLS) can be affixed to the top of the Mod II(which is shown here)and Mod III units. The SSLS adds three inches to the overall height of the Shaft Lok unit. The SSLS replaces the need for a cable. Push on the black palm knob to lock the unit. To unlock the unit start the engine and engage the transmission. Shaft Lok automatically unlocks.
