Rusty's Spicer Axle Block Off Plate & Seal Kit

All 1987-1995 YJ Wranglers and many XJ Cherokees came with a reverse-cut Dana 30 front axle that has a Center Axle Disconnect (CAD) feature. This can be easily identified by a medium-size cast housing integrated into the passenger side axle tube. This assembly uses a two-piece long side axle shaft that disconnects from the passenger front tire when the vehicle is in two-wheel drive.There are a couple of issues with this design. First, it's not as strong as a one-piece axleshaft. Second, the vacuum-operated system often stops working for one reason or another, which leaves the vehicle stuck in two-wheel drive. Lastly, it really doesn't serve much of a purpose because the axleshafts still spin (so there's little reduction in drag) and the transfer case does not send engine power to the front axle in two-wheel drive anyway.Luckily, it's easy to upgrade the two-piece design to a much stronger and more reliable one-piece design. The inner axleshaft from a TJ or non-disconnect XJ will slide
