Mountain Off-Road 98500 Ford 8.8 Axle Swap Kit for 87-95 Jeep® Wrangler YJ

Catalog #: 12590.0250
Mountain Off-Road Part #: 98500
Installation Kit for 1987-1995 YJ's - No paint. This Ford 8.8 install kit includes the following items: 2 weld-on anti-wrap style spring mounts for the housing, 4 U-bolts, 2 U-bolt plates, 2 weld on shock mounts. All hardware is unpainted.

Features of the Ford 8.8 install kit are as follows: same lug nut bolt pattern; disc brakes (95 & newer); 31 spline axle shafts; 8.8" diameter ring gear (D35 is 7.5"); 120% stronger than D35; only 20 pounds more than D35; trac-loc differential stock; and 3-1/4" diameter tubes (strong!).

You now need to find the complete rear axle assembly from a 95 or newer Ford Explorer from a salvage yard. Then, remove (torch) the Ford mounts (spring & anti-sway bar). You may also need to change the gear ratio as most Explorers have 3:73. The Ford 8.8 kit gives you the following: new, weld-on anti-wrap spring mounts, weld-on shock mounts, U-bolts and U-bolt plates.

The width is almost the same. It is 5/8" per side narrower than the D35. This is a very minor drawback and will work if you have wheels with less backspace than stock. 7/8" thick wheel spacers available. No cutting or custom fitting is needed.

Note: The Ford 8.8 install kit is not compatible with anti-lock brake equipped Jeep® vehicles!
