A 2 speed rear gear would be awesome!!....but I have never heard of such a beast for a truck this small.


I do know that gearvendors sells a double OD option.....but don't think it will work on our 4x4's tho.

you can make the gearvendors OD work...you just cant run it in 4 wheel.....either way it just goes behind your trans, or in this case the transfer case.

fixing to drop some 3.73 in my 99... i will let you know how it turns out. There is already a pretty good discussion for the same subject lower down the page on 7.3 drivetrain section. Got me some Yukon 3.73 gears for 350 bucks. I have heard of people doing 3.73 in rear and leaving 4.10 in front. just make sure you dont run it on hard surface like that.

4.10 to 3.73 is only a 250 OD RPM diff. 4.10 to 3.54/5 is a 500 RPM diff w/ OD. I know I did this. took a 2 weeks between switching axles ( had 2 laying around) End result:...........waiting for my gear vendors unit:-D

yup.. when I bought my last truck the guy had 4.10s in back and 3.73 up front. it would pop and jam up every rotation. definitely wouldn't leave it like that in case you need the 4x4
