Hey Mike, 3.54 are very good for stock tires but with 36 as you mentioned you need lower gears. 3/4 Ton axle stuff will not interchange with 1/2 ring and pinion. Remember being a 4x4 the front and rear have to be the same ratio. The was a ratio of 4.30 gears. I had some in an Inetrnational 3/4 ton pick up. A good gear for what you want. If you are going to do some crawling or serious off roading then the 4.56 would be better. Dana 44 are a good axle. I would be tempted to go to Dana 60 in the rear and up grade the front brake to eight lug drums or rotors. They can handle more punishment of big tires and some real torque. It depends what you are going to do with your rig. Just a few suggestions for you. Do you have a stick or automatic? What engine are you running? Henry
