    I'm sure that this has been answered before but would it be worth going to 4.56 from 4.10. I have a 700r4, 10 bolt front, 12 bolt rear with 35's. I don't see 1 ton in the near future.
    Thanks

    I don't know if I would go from 4.10 to 4.56 in a set of 1/2 ton axles although I replaced my stock 10bolts with another set of 10bolts with 4.56 gears I would not spend the money on regearing them right now. Depending on how hard you wheel it. Do you keep breaking now because with 4.56 gears and 10bolts and 35" tires it is not a matter of if you will break it is when.....Jason

    It wouldn't really make a difference going from 4.10 to 4.56. If you have the money it wouldn't hurt. I ran 35's and 4.56's and never had a problem w/strength until I got 39.5's. The axle shafts should be able to withstand 4.56's and 35's.

    One-ton swap isalmost the same price as re-gearing... look hard enough, and you're sure to find one-ton stuff already at 4:56. Should find 14FF around $250 in the yard, re-gear front 10bolt for around $500, 8-lug adaptors for front @ $200 or so, then new wheels @ $300 for a set. Total:$1250.00.
    Typical re-gear cost w/ labor:$1100.00

    Just do it, you won't regret it. As soon as my lift and tires arrive, 1-ton is next (unless I buy DP_90k5's bumpers) /forums/images/graemlins/thumb.gif

    That is actually a 3/4 ton swap /forums/images/graemlins/wink.gif

    If you are going to stick with 35's for a while I would try looking for a rear 14 SF with 4.56 and 6 lug axles then regear the front. This way you are upgrading your strengh a little when you spend the money yet keeping a respectable amount of ground clearance. Plus you keep your current wheels and tires saving money over 3/4 or 1 ton gear.

    I don't think any factory 14 bolt SF will have 4.56 gears. AFAIK, 4.56s weren't offered in 3/4 ton trucks (and certainly not in light duty 3/4 tons with 6 lug axles) and 14 bolt SFs were not offered in 1 ton trucks.

    I was thinking more along the lines of someones discarded project that was already regeared... For the cost of regearing a 10 bolt there is a fair chance at finding a 14SF that is already set up.

    That's true...never thought of it that way. That'd be great. /forums/images/graemlins/thumb.gif
