The Alloy USA® Differential Cable Lock Kit is a permanent replacement for the
failure prone OE vacuum disconnects system on early model Wranglers and
Cherokees. The kit allows you to engage and lock the front axle from inside the
cab. A 1inch pull of the cable ensures you will have four wheel-drive when you
need it for as long as the transfer case is engaged. The Differential Cable Lock
Kit is more cost effective and easier to install than a locker or posi-trac
system.For YJ 1987 to 1995 and Cherokee 1984 to 1991.
