i currently have the dana 35. I plan on sometime going to the 8.8 or dana 44. I will put an ARB locker in it when i do the swap. I have a 4" lift with 33" tires and am running 4:56 gearing. Now, when i do the axle swap, i would like to run 35" tires. Would the current 4:56's work with the larger tires or should i re-gear to something else?
I don't think your gears you have in your D35 will crossover into the D44 or F8.8.. You will still have to buy 4.56's for your rear again
I know the gears wouldnt work. I am wanting to know if 4:56 would work with the bigger tire. I already have 4:56 now. If they work with the bigger tire then i wouldnt have to replace the front. Thats why im asking if they will work with the 35" tires. If not then i would have to change out the front also.
If you have a D35 under the back, you should have a D30 up front. Do you think the D30 will hold up to the 35's? Even though you re-geared I don't know if they will be strong enough to hold up if you wheel alot.
The D30 holds up fine to 35" tire and a locker, within reason. With upgraded alloy axle shafts, it will hold up to nearly anything you can throw at it so long as you stay with nothing bigger than 35" tires.
Regarding regearing from 4.56 to 4.88, that depends on your $$$ situation. You are already having to regear the rear axle. If another $500 or so to regear the front axle too is not a big deal, regearing both to 4.88 would be a very good thing to do. 4.88 with the 5-speed and 35" tires is the ideal ratio for both highway and offroad use. I had that combination for years and it was really sweet both on the highway and offroad. 4.56 "works" for 35" tires but 4.88 is a better all-around ratio for that large and heavy of a tire.
