Wanted: transfer case

[Jacques Reed]

Hi Larry,

To each his own, but I am on the originality side like yourself. I had a two speed transfer case in my F15-A and spent a lot of time and effort putting it back to the single speed case. It involved welding up and grinding back the elongated mounting holes burnt in the transfer case brackets to accommodate the larger two speed case.
I also had to source the correct rear floor plate and single speed change lever.

In support of the two speed however, if one is running 20" wheels instead of original 16" wheels then there is some merit to the two speed case in a F15-A. The low range is 1.87:1 which makes for a lower speed in 4WD. If you don't intend a lot of serious off-roading then the single speed original setup should do just fine.

There are some misconceptions around that a two speed case give you more road speed. I have heard it repeated a few times which is not the case as both single and two speed only give 1:1 ratio in 2WD. It is not an overdrive.
In fact. with the extra weight, a two speed case would probably affect top road speed slightly.

Cheers.
