help finding gear ratio

[lunchbox]

i just swaped in a ten bolt that i only plan to run untill i can find a semi floater 14 bolt. i know that a guy posted a formula to find the gear ratios in this new ten bolt but i couldnt make it work, here are the numbers for that i found on the ring gears

2 GM 1235124 15 41 1 83
and
1 GM 3988518 11 41 11 86

If one of the axles does not slip then yes. Why did you change axles? Why not change the gears out it takes a little time but is doable.

i had to limp home out of the middle of nowhere when i blew the diff soso the ring gears are crap and i dont know how to change them .and secondly i am flat broke and it was 1/2 off at the pick and pull last weekend so i got the axle for 53.00$

Gotcha, Just stay out of 4x4 until you can get your new rear axle.

one way to fudge it...

I bought a 71 K5 that had a 3.73 front axle,and a 3.07 rear someone stuffed under it just to sell it..I ran it for 2 years that way--I put 33" tires up front,and the stock 235/15's in the rear,that helped "match" the ratios close enough so I could use 4wd without busting up the transfer case or hubs!..you could still feel the front wheels going slightly faster than the rears,and it was a bit of a chore to drive in snow ..but it did great doughnuts!..

When I sold it,I gave the guy a 3.73 rear axle I found for it,but never put in..he never installed it either,he moved to TX with it,where he'd probably never use 4wd anyway..

help rear end blown up

so i blew the spider gears again so i decided to buy axles with a detroit locker 3.73 and stock is a gm 1235124 15 41 2 83 will they swap evenly no hassles?

41 divided by 15 is 2.73 not 3.73.

First off, it would be respectful to make your own post and not bring your question into someone else's post.

If you bought a complete axle to swap your current broken one with then we need to know what the replacement axle came out of and we also need to know what you're going to install it into.
