Question 12 bolt or 14 bolt

OK, I have a waggy thats going spring over here shortly. I only plan on doing the SOA and maybe 1" shackles for now. This will give me alot of clearance for the 35's I have, I don't want to go any bigger b/c its my DD right now. I have a set of 3/4 tons, 44/14 bolt, and a set of heavy 1/2 tons, 44/12 bolt. If I go with the 12 bolt am I going to break shit. I'll have the 360 on propane, auto trans, D300, and a BAM-BAR linked to a truss in the rear.

Pros:
14 bolt
-the 35's have new 8-lug rims right now
-full-floater
-cheap disk conversion
-can shave 2" off the diff easy

12 bolt
-has eaton locker already in it
-better ground clearance (35" tires)
-lighter

Cons:
14 bolt
-heavy
-huge
-open diff
-if diff shaved need costom cover and have no bolts in the bottom

12 bolt
-6-lug
-disk breaks are $

The waggy wont see alot of hard wheeling but it'll see alot of trails around mich and camping trips. What do ya'll think? Anyone break 12 bolts, what were you running at the time and how did it break?

id go 12 bolt. 30 splines and will run you 35's NO problem. a 14 bolt will hang pretty low to the ground and be excessive for that size tire.

I think you should stick to the Gov-lok ID thread.



Run the 14-bolt and shave it. Pick up a Gov-lok someone doesn;t want until you have $ for a locker. Sell the locked 12-bolt on Got Mud. You're talking about wheeling a FSJ, so the weight of the axle shouldn't matter to you all that much in the first place.

You got a point about the weight. Who could machine the ring gear and what would that cost? What about the lack of bolts on the bottom of the diff cover? Even with a rock ring it looks like it would be easy to peel back, there would be ~8" span between the bottom bolts.

Just keep the stock axles if you are only running 35s

Well, I don't like the stock axles, AMC20 and 44. I like the full width look and added stability. My 44 (the factory one) is set up for spring under and a drivers drop, I want to put my D300 in it without the flipkit ( I know, I will use cable shifters and make my own cross member/trans mount). I know its alot of work and done a ton of research but these are the upgrades I feel needed. It is a DD but I tend to break stuff alot.

Looking like the 14 so far, double checked the gears and they are 3.73 in both but I have a set of yukon 4.10s for the 44/14. Whats the split on a 12 bolt carrier, would I need a new one for 4.10s?

I went form a 12 bolt (broke the housing) to a 14 bolt, I belive it was a good up grade for my blazer. It had better gears and with dics uses the same brake parts as my 10 bolt now. I shaved the bottom before put it in, I just cut the lip off. If you cut the whole bottom off like you are talking, welding it, getting it to seal, and the diff cover become things to deal with. With my 35's it does tend to anchor its self on ruts and rocks some times but if you watch where your going it can often be avoided.

that truss is the shiznit.

what year is your waggy? i may want the shafts from the axles if they are of the right year. i need the widetrack amc20, and the 44 should be the same.

fyi, just if you didn't know, the amc20 got wider after 1981 sometime, as i experienced this when i bought an 83 amc20 and myjeep had an 81 in it already.

2nd person to ask, this is a DD so the rear axle isn't avalible yet. Waggys a 86. What do you mean the 44 should be the same?

if you have a extra 14 bolt with a open carrier and want to sell let me know.
