Alright everyone I am ready to rebuild my front and rear diffs, I am currently runnig 4.11. I did some searching around here to see what everyone is running for gears and there seems to be a pretty good mix out there. I have done the math and think that for my application (a daily driver that will see mostly city driving but needs to be able to handle at least 70 mph) that 3.73 would be good. However knowing that it looks good on paper without experiencing it in real life makes me hesitant to spend the money without hearing from others with the same setup as mine. A big concern for me is the in town driving with those gears since the ZF is a wide ratio, I have a hard time between 2nd to 3rd and 3rd to 4th. Just want to know your recommendations and experiences/ setups.

I am running a rebuilt stock 858 CPL in a 1977 F150 shortbed. The 4bt is hooked to a gas ZF 5 Speed that is married to a rebuilt NP205 transfercase. I have a Dana 44 up front and a ford 9 inch in the rear running on 33's, I want to keep the 33's. The RPM range that I see the best power at is between 1800-2000 RPM. With the H1c I am currently pushing around 4 psi cruising at 55mph with an all time high of around 25 psi in town when I push it to move.

3.73's and 33's are and excellent choice. Mine is a daily driver, does every thing I ask and better.

4.10 & 33" s are what's on my jeep. If I was staying with a gas engine 4.56 would be just right, but I'm going with a 453t. So the 4.10s are right around 2000 rpm at 100kph. It Dogs down my 4.0 liter at 85-90 in OD but will cruise at 110 happily in OD

Hope this helps

im running 14 bolt rear with 3.73 gears and 33 in tires. i rn a nv4500 dodge tranny but the over drive should be similar to yours. the 3.73 are perfect! good take off and at 65 mph in 5th gear the engine is turning 1740 rpms.... so 70 would be around 1850 or so.... also its at 1800 rpms in 4th at 45 mph wich is the liit on a lot of the roads around here....
