Check the tech section.

What Comes With What?

For swapping into a Ranger, a 4.0L Ranger donor is the best choice, as it is in most cases a bolt-in affair. Explorers and others will work, check the notes below for specifics. Pre-1990 Rangers will need minor driveshaft modifications, or the driveshaft from the donor, as the driveshaft flange on pre-90's is smaller. All axles listed below have a 5 on 4.5 bolt circle.

8.8 Users:

Models Years Notes
Ranger 4.0 1990-1992 Width is same as other pre-93 axles, 28 spline
3.08 (4x2), 3.55, 3.73 and 4.10 (4x4) factory ratios
Either limited slip or open differential
10" drum brakes

Ranger 4.0
B4000 1993+
1994+ Width is same as other 93+ axles (1.5" wider than pre 93), 28 spline
Ratios and differential options as noted above
Ranger FX4 2002+ Width is same as other 93+ axles, 31 spline
4.10's and Torsen limited slip from factory
Explorer
Navajo 1990-1994 Width is 1.5" wider than 93+ Ranger, 3" wider than pre-93, 31 spline
Spring perches must be fabricated and welded on top
Stock spring perches can be used to lower the truck (like a flip kit)
Shock mounts must be fabricated and welded on
Very common to find ltd. Slip, usually 3.73 or 4.10 (4x4) gears

Explorer
Mountaineer 1995-2001 Same as above, also has rear discs
