Outer Limits 4x4 Board

what r the pros & con of both 9in & 14 bolt which is stronger

The US guys seem to like the strength of the 14 bolt over the 9" if ya read through Pirate4x4.

the 14 bolt rear is much stronger than the 9 but also heavier. There are a fair few things you can do with them. Plenty of after market stuff now but not as much as the 9 inch. If you're looking at a 14 bolt then also look at a jana 76 which is a Dana 60 with a 70 center.

14 bolt wins.

Heaps of aftermarket goodies for them, but a front is a full custom only deal. Build them right and they're the last diffs you'll ever need.

ok 14 bolt it is then where is a good place to get my parts i want a disc brake 6 stud conversion & axles . what other mods should i do ?

I'll txt you later on bogs

either import a set of axles or get a set from yukon enterprises down at Euroa. the guy's name is Joe Dahmpet.

The disc brake conversion isn't that hard but what makes it hard is trying to retain axle mounted handbrake on the calipers. If you have a driveshaft hand brake then it's a LOT easier.

6 stud conversion is a little trickier. Some 14 bolts came with 6 stud in the smaller cars like the C/K 10 etc. But there's also a chance they might be semi float. All the dually hubs are 8 lug. Ask around a bit on Pirate4x4 to get more accurate answers.

I've got alloy 14 bolt thirds in my build. So i can tell you what they're like in a few months

Good to see everyone moving away from the toy/Nissan Crap.

Perhaps look at the Dana 70, ff and 6 stud choices. Huge brakes.

If you want to be really cool, build a jana87.

The 6 stud part is what is going to be the hassle whichever way you go. You are obviously ready to put down some coin, why not another k on 8 stud rims/beadlocks

Solid do a bolt on 6stud conversion for the 14bolt. And I'll be running a hydraulic handbrake so I got a disc brake conversion for 300-350

Cheap to get parts for

Jana 76's are a real option. Plus you can get 6 lug hubs to suit stock D60 on to yota/nisshit rim applications from Solidaxle for a reasonable price.

You beat me to it Evan

I think the 14b is so commonly used in the US cos theyre common as mud there where a junkyard 14B can be had for $150. Not so easy to find here? What are you building? The 9" axles seem to be very popular in the lightweight ultra 4 style go fast buggies.
Dana 70 rear is a good option as zoltan mentioned.If you dont mind the extra weight. Theyre fairly common here due to the large ammount of dual real wheel F350s in this country, most of which are junk now cos of their age an rust issues. Ive seen quite a few rusting in peoples back yards during my travels around central queensland.
I got my rear D70B (4.56 ratio, 35 spline carrier)off an old guy in rocky for $300. Its 8 stud but thats ok just means ill buy 8 stud rims if I can find/import a d60 front diff.. Ive also been looking into the possibility of getting another D70, removing the axle tubes an getting custom tubes made to suit a front steer application with reid knuckles etc.
From what I understand after skim reading the Jana 76 thread on Pirate, you need a high ratio dana 60 carrier to fit the D70 gears into without a fair bit of custom housing machining

^^
Nope you use a d70 carrier into a d60 housing.
This is what I'm doing for my front diff.

The 9" can be built very strong With all the available add ons but they are more expensive. I can do jana76 front, 14b rear to suit my 6 stud rims for the same price as a 9"front

Sorry worded that wrong. I meant to say You need a high ratio D60 housing to fit the low ratio d70 carrier into. Or am I still on the wrong track an theres no difference between the high an low ratio D60s like there is with the D70s? Been a while since I looked at any of those threads

It's all about this thickness of the CW and the flange offset. I think there is only 2 different offsets, wouldn't be hard to track down both carriers just in case

I do like the removable pinion housing of the 14b tho, makes it easy to fab up a pinion/yoke/uni guard.

It comes down to who your contacts are, chev Dana, Ford Dana, or international its all going to be hard to get replacements quick. Gone will be the days where you could 'borrow' somethings from the tow car or a car in the car park

^^^ this is tru, robbing parts is hard. But theoretically if you do it properly it should be alot more reliable than any nissan or Toyota poop

You say this like you've had nothing but trouble with yours..

Where can you get 14B 6 stud gear from mate?

I have had some issues Ethan but I've had spares.


Read up nath, solid do 6 stud hubs for 14b

what about disc brake conversions i have found them but none of them offer 6 stud rotors do the just redrill them ?

not sure how they go on exactly but i have been told a few times that the 6 stud hubs are a direct bolt on job

Where would the best place to go looking for a complete D60 front and a 14bolt rear be? Also is there a d60 rear diff?

These will be going in a V6 powered buggy, and only running 37s. so not looking for something to handle 500hp

No need for those axles with only 37's mate. You'd have the same clearance as a Lux on 31's. Haha

i possibly may part with my 14bolt disc rear.... give me a yell in a few weeks

Application people, bigger isn't necessarily better. People race the hardest courses in both 9's & 14's so it all comes down to what you can afford & is available to you & where/what application you require.
To be honest a stout D60 f&r is more than enough for most & parts are very readily available.

I agree with Brooks's on bigger isn't better after seeing a 14bolt in person they are just a big anchor, the only reason there considered by most Americans is cause there cheap, and the stud pattern matchs dana60s, either a 9" or patrol center with Dana outers are a better options unless you like getting hooked up a lot on rocks

Yea but shaving a 14bolt is still going to be cheaper than setting up a patrol center with Dana Outers. Or a strong 9"

You won't shave a 14 bolt that much to improve the anchor. I see no sense going a 14 bolt under 43" tyres, but that is just me I guess. I do however like Milo's 3rds.


brooksy

I guess the must always be a compromise. Lose some clearance for better strength over any jap setup and still keep it more affordable than a 9"
