Im doing 5.13s in my 14bff right now and have not yet decided on what to do for the front. Of course im going 5.13 but with my puny 10 bolt am i going to be asking for some serious carnage when i get goin in 4wd? I have seen pictures of how small the pinions are and im kinda scared to spend 140 for the gears and 85 for the install kit.

What should i do?

If i replace the carrier will it make the pinion any stronger (4.10 up carrier)?

Is this something worth getting a Dana 60 over, because right, now im only going to be running some easy trails with an open diff. and 36s.

Thanks

it all depends on how much you can get a front 60 for. If it were me I'd probably buy the gears, install them myself and save for a 60. I know this sounds ghetto but its probably better to learn to set up gears on a front that will (obviously) only be used off road. Also, even if they arent perfect, youre gonna swap the whole thing out eventually anyway. I'm not saying just toss them in there, make sure you read about it and try to get someone with experience to help but the more you learn to do yourself the more you save on labor and can spend on better parts.

im in an auto tech class, and ive got a teacher who builds all kinds of chevys (atleast 7) for raceing, and there are some other ppl in the class who have done installs before. so im going into this install with quite a bit of help.

i guess ill stay with the 10b for now thanks :D

5.13 in a 10b will eat axle shafts like a demon i doubt it will even faze the pinion.

even if i keep the diff. open?

36 is maxxed out for real use even with med. gears, 4.10/3.73. adding 5.13 is just going to pop the splines right off at the neck. the open diff will be a minamal safty factor, the one thing that is going to help [about as much as the open] is the auto tranny.

you can do it, and it may last a for a few trips but if you start pushing it, its going to fail pretty fast. even if you dont shear the shafts off with a quick pop, they will stress fracture fail with the weight and leverage of the truck+5.13.

your tire choice will make a huge difference in how long it will hold up. a weak street/at tire will be your best choice, low/mild traction will ease the the stress put on the shafts, to an extent. get some swamps and your done.
the 5.13 are a good swap for a toy or jeep, something light.


you realy need to either save up some cash for some beef 10b shafts or get the d60 for those gears. get just the inner shafts first they are more prone to fail[poor design]than the outers and easy to deal with busted outer than dig inner parts out of a diff.

hmmm, well i do have an auto tranny, and i am kinda light on the foot.

i think i will do it for now, and down the line, get a 60.

the trails i plan on doing arent going to be very difficult and i dont think i will be seeing too many rocks.

i am just going 5.13 now, so when i get bigger tires i wont have to regear 2 axles.


thanks again

i thought the same way. i started going bigger and better and started failing. the 33's with the auto work great. then came the 465 with the 33's, never got a chance to play with it hard just light mud. followed by the 36" tsls, and thats when it went south.

first failure was not entirely the tire or tranny, my steering stop busted and over flexed the joint, the auto would have deffinetly not forced it to fail. #2 was steering stress failure, again. not over flexed but turned and stressed.also sheard an inner spline. #3 was a direct tire/tranny failure, long fractured the outer. #4 was a shear break of the outer. again leverage + traction + weight = busted stock stuff. various ujoints where also destroyed but not relivant.

just keep it easy, have fun, and carry spares.
