31 spline

Rangers have a 28 spline 8.8, the Explorers all have a 31 spline 8.8. It's a very popular upgrade for Rangers to get a 95-up 31 spline 8.8, b/c it's stronger and has disc brakes. Rangers are spring-over, so it takes a welding job for the perches and shock mounts, but it's a worth while upgrade. Be happy you don't have to do that (unless you want rear discs).

Best,
Brian

31 spline

Explorers have the 31 spline. Rangers are the 28.

That depends

My 94 EB 4x4 had 28 spline, so don't be too sure that you have the 31 spline. If you have the numerically higher gear ratio (3.73 or so) than you probibly have the 31 spline though.

yeah....i got 3.73....so i probably have the 31....oh well....
