So I have a dana 60 rear and 44 front from an 89 dodge that I'm really tempted to put under my ranger (1993 xlt 4x4, 4.0 OHV, automatic) with 35's. I am currently running stock suspension with 33's and the stock 3.73 gear ratio. I'm not afraid of the fabrication that it is going to require but the power to weight is scaring me a bit. I was already planning on a full dana 44 swap this summer but ended up finding this set of axles. I believe the new axles have either 4.10's or 4.56's in them. Would I be alright to run the extra weight? I do have to do some highway driving to get to the trails in the mountains.

 

Welcome to the forum

I think its only a few hundred pounds more, if that, so same as extra gear in the bed or a passenger, should be fine

Axle weights seen here: https://www.therangerstation.com/tec..._weights.shtml
Grain of salt as they are all "about's", lol

The wheels and tires are another thing if you go bigger, lol, the 4.10 or 4.56 would really help with current 33" and larger

Ratio, tire size, RPM and speed calculator here: https://spicerparts.com/calculators/...rpm-calculator

You can fill in the blanks to see whats best for your driving
4.0l OHV makes best torque/power at about 2,400rpm, so you don't want to be much below 2,000 RPM in OD for highway driving or you will be lugging the engine, and this depends on the speed YOU drive at on the highway, lol

A4LD Automatic OD ratio is 0.75 for calculation

Once decided, you will want to change the Driven gear on transfer case speedo cable hook up to send accurate speed signal to computer to get correct shift points for the automatic transmission

Transfercase has a 7 tooth Drive gear, needed for calculation of Driven gear teeth
