Hi all, first time poster here.
I have sifted through some differential threads here but I couldn't find one that answers my question(s) so I thought I would start a thread. If there is a thread similar, please point me in that direction..
I have a 2000 E450 16 foot cube van that I use for long haul highway runs about 98% of the time. I know this vehicle is rated for roughly 14,000 lbs but I would say the absolute max weight I would have in the truck is 5000lbs.
The truck is bone stock with a DP tuner 60hp econo tune.
My question is, has anyone swapped the stock 4.10 diff to a 3.73 or even a 3.55? I find for 65-70mph cruising the engines revs quite high even though the truck has overdrive. At 70mph it is around 2350-2400.
If you have swapped the diff, have the results been good for MPG and noise level?
Also did you have to reprogram for shift points or anything else?
Lastly, do you feel like it was worth the expense?
Thanks
