Features of our 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 that we sell 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. We have 7/8 thick wheel spacers available. We also have the correct cables for the emergency brake available as a kit that are a direct bolt on and super high quality. No cutting or custom fitting is needed. Note: Your ABS will need to be disconnected and will not function using this Ford 8.8 install kit. Contact us for more information on our Ford 8.8 install kit.

QUESTIONS & ANSWERS
Ask a Question-
Hi, I am finally getting around to installing this 8.8 with your kit (excellent workmanship) and just realized I don't know what the torque should be on the new U-bolts. Looking around the internet I found 65ft/lb for a 1/2" U-bolt is common. They measure closest to 1/2" so would that be the correct number for these as well? Also, I know this is not part of the kit but I am installing new leafspring center bolts (5/16-24) and was wondering if you'd know what torque would be correct for those as well.
100# for the U bolt and 24# for the center bolt

Does this kit include instructions with measurements so i know exactly where to weld everything on at and what the pinion angle should be?
Travis,
There are no install instructions included in the 8.8 kits. What you need to do is:
1) take out the old axle
2) Install the new axle and center
3) Set your pinion angle (see Tom Woods website for a good tool calculator to set pinion angle)
4) Bolt on and tack weld your MORE 8.8 kit parts while axle and pinion angle is in place and set
5) Remove tack welded 8.8 parts and weld complete
6) Re-install 8.8 welded kit.

will this work for spring under (stock) set up? I see where you say it was designed for SOA....
It will work but you will need to shorten the spring perch aproximatly 1" each side to accommadate the curve of the spring.
