Rear gear change Nashville TN

4.30 is the ticket with the V10, 4.56 too high for highway use. Curious why you're looking to get this done while you;re out of town?

Look for Randy's ring and pinion in Franklin

Although I don't see it on the website so maybe it is closed :(

If you have a dually its a Dana 80, or SRW is a 10.5 Sterling
If you are running over size tires I would go to a 4:30 or 4:56, but if stock a 4:11 or 4:30
Probably $1000 parts, and $500 labor ball park.

I loved that I could do it myself. A ring/pinion was $200 plus $100 install kit. I used to charge $150 labor an axle. I couldn't imagine spending 1500 on an axle that didn't have an Arb in it.

4wp is usually pretty good. They thing about them is they will warranty their work, which may mean something to you. They're a lot of small off-road shops in TN though that will do a fine job.

4wheel parts is a chain of stores, kinda like Camping World. Hard to say good or bad about them in terms of service, I think of them as a place to buy something, not to have any work done there

I would recommend 4.56! I have an 02 with the 4 speed auto and part of me wishes I would`ve went to 4.56 even with the stock size tires. I went from 3.73 to 4.30 and it was a night and day difference it tows my 9200lb TT with no issues. With the 5 speed 4.30 would be good, 4.56 would be great.
BTW, is this an every day driver or Tow Vehicle only? That may make a difference on whether you go 4.30 or 4.56.

I would also recommend a custom towing tune from 5 Star Tuning. They are the go to tuner for Fords Triton powertrains, specifically the V-10 4 and 5 speed autos. the difference is truly amazing. between the gear change and the tuning it will turn your E350 into a towing monster!

And wherever you choose just make sure you do a lot of research on them. you want someone that has done them a lot. check out the reviews if available, or ask in depth questions, such as how they do it and what all do they replace?

I strongly suggest you go check out a gear chart for your particular vehicle.

Jumping one ratio to 4.10 will barely be noticeable. Only a couple or three hundred rpm at highway speed.

Figure out what rpm you want to cruise at at work it back from there.

Not sure if still around, 4lo.com you could put in tire radius, final trans gear ratio, rpm wanted, speed, it would tell you axle ratio needed. You night find a 4.33 being a good option too.

4wheelparts? Maybe. Some are good and some are horrible. It seems more of the latter.

I would strongly recommend you tap into the local Jeep community. That crew is forever changing gears and will put you in touch with the shop that can really set them up right.

BTW, what are you changing from / to?
