KAM Difflock

The KAM Diff Lock is electrically controlled via a heavy duty solenoid located inside the diff pan. A cable runs from the solenoid to the an illuminated rocker switch in the cab that engages the diff lock. The solenoid itself is a dual coil type, electronically controlled and protected by an integral solid state commander module.

A short 45 amp burst of power activates the solenoid which then preloads a spring. The spring then forces the sliding dog along a newly patented locking tube witch locks the sliding dog on to the carrier. The diff locker is now engaged and give continues drive to both wheels. A constant 0.5 amp draw holds the solenoid in a locked state. This new tube design means that you can use your original shaft or shaft that have been purchased previously. If you do bead a shaft then the diff locker will still work
