rear end
New here guys,I was wondering if I could get some advice. I have a 96 350 crewcab,dually,I love this truck. she is almost back to mint cond.,but anyway
its gotta 5 speed man. and I run 2600 rpm @ 70mph. and I would like to drop it down a bit,I wanted to switch to 3.73s but they tell me I can only go to 3.55s. I do haul trailers but not all day everyday, maybe the heaviest I ever
really haul is about 8500 to 9000 lbs. but i average about 5500 lbs.
I would say I pull only 6000 miles a yearout of 20,000 total.
would switching to the 3.55s ruin my haulin torque?

A qualified mechanic should be able to rebuild your differential and swap your ring and pinion set with the ratio of your choosing. Without you having to dig up a junked rear end. Someone familiar with working on differentials can have you set up in a few hours of charged labor.
If you have 12 bolts on the back of the rear end- search for an R&P set for the Ford 10.25" rear end. If it's 10 bolts its the Dana-70, Dana 70-U, Dana 70HD or Dana 80 rear end. The 10.25 and Dana 70 U have aftermarket and OEM ring and pinion sets at 3.73. I'm not sure about the other rear ends.
Good luck
