      • Differential Cable Lock Kit
      • Backed by a 3-Year Warranty
      • Made for Lifted 1987 - 1995 YJ Wranglers with Front Dana 30


      Specs. This Differential Cable Lock Kit is the perfect choice if you're dealing with the failure prone OE vacuum disconnect system. This is a permanent replacement that lets you engage and lock the front axle from inside your Jeep. Just pull the cable and you'll have 4-wheel drive as long as the transfer case remains engaged.

      Construction. This cable lock kit does require advanced mechanical skills to install, but it's easier to install than a locker or posi-trac system – plus it's more cost effective. This product is backed by Alloy USA's generous 3-year warranty.

      Application. This kit fits 1987 - 1995 Wrangler YJ models that are lifted 3 inches to 6 inches.

      Fitment: 1987 1988 1989 1990 1991 1992 1993 1994 1995 Details

        Good Product

        Ive had this cable lock installed for about a week and its worked perfectly so far. I will say the instructions could be a little better.

        Good for now

        I bought this kit because after lifting the jeep (4") and disconnecting the sway bars, the vacuum lines kept pulling off the disconnect switch at the differential side. The lever works ok but you have to let the jeep roll a little to make sure it is engaged. I wish the knob that goes under the dash was smaller because it looks a little odd hanging under the dash as large as it is. As you can see by the picture it's as large as the transfer case lever knob. Also the cable is pretty stiff so it's difficult to run under the hood and keep off of exhaust and moving parts.

        4wd cable

        Cable system relatively easy to install. Works well. Only problem with the kit is the cable would not fit in the under dash bracket. Had to enlarge the hole about 1/16”.

        Better than stock

        Fairly easy to install.just be patient.i was really happy to be able to get rid of the stock lock set up.the cable is a bit stiff at the start but otherwise I'm very happy, and now more certain that the front axle is engaging

        Poor instructions provided

        This part is very complicated to adjust and seems to be way to long. I ordered the cable for a 4-6in. Lift as I currently have a 4in. The cable had to be looped in a large circle above its connection point in order to deal with the excess length.

        Works as advertised

        So far so good. A little clunky to operate but overall nice to know that the 4wd is engaged for sure.

        4x4 cable disconnect

        Not real impressive with the quality of this product. 4x4 sensor wire held on with heat shrink (it fell off before install) and had to do about 20 min of polishing to inner housing so shift fork would slide. Lot of money to pay and still have to use your old shift fork. Would not suggest this product to any of my friends.
