View Full Version : 14 bolts

02-25-2007, 01:13 PM
So confused here, been looking and can't find much info. I have a 14 Bolt Corporate which is a full floating diff...so I am told (looks like one to me) ....with a government locker which I want GONE go fuck yourself so I can install my Detroit. The only info I can find is on White Knight, guy says just change the carrier and your good to go...says to weld it instead of wasting money on a locker too but I have a Detroit already. So I go to the junkyard and if the idiot will sell me anything all I need is the carrier from a 14 bolt?

Also, the 14 bolt I got is from a van, apparently they are 3 inches wider than a truck 14 bolt?....good or bad? [cheers] cheers and beers :dontknow:

Sounds good for the width but your Detriot is it's own carrier so you don't need a carrier from another 14 bolt unless your detriot is a lunchbox locker then you will need the carrier[cheers]

14 bolts use the existing carrier

"Detroit Locker GM 14 Bolt 10.5 30 Spline - Requires open diff case (6258336 4.10 & Down or 6258340 4.56 & up)

The Detroit Locker maximizes traction by delivering 100% of the torque to both drive wheels. It is engineered to keep both wheels in a constant drive mode, and has the ability to automatically allow wheel speed differentiation when required. Used by both professionals and enthusiasts. Applications are also available for C-Clip style axles."

Here's a picture of it....it's from Tractech :dontknow: it's called a "nospin" Detroit Locker.

[iagree] to put the detroit in the old style 14 B FF (the pinion is mounted in a flange bolted on to the front of the diff) all you need is the stock open carrier, remove the 4 spider and 2 side gears and install the detroit in place of.

There is a flange with 6 bolts the pinion is mounted in...just went and looked.

Then yes Joe the detroit in the picture is the right one for your diff and you will need the open case carrier when you take the ring gear off the carrier will split open take the spiders and the side gears out drop the detroit in the 4 round tabs sticking out will go where the spiders were close up the carrier bolt the ring gear back on and then remove the bolt and washers out of where the axles will go(that bolt is to hold the detroit together until it is in the carrier if you remove it before it is spring loaded so it will spring apart)

okay thanks guys, thanks Mike. I got this rear end and they are too heavy to move around lol so I hoped I could use it on my one ton. Weather is getting warmer so I want to make sure I got what I need. [cheers]

If you want all the info on 14 bolts go to pirate 4x4 and under tech Billavista has an article called 14 bolt bible awesome article

02-25-2007, 07:41 PM
Billa's 14b bible is a good overview, but not as detailed and accurate as the D60 one.

Post your questions here. I've laid hands and/or disassembled most of the possible variations.

The van housing is less common, but often preferred because it's very close in width to an 8-lug front axle. (Truck ones are 2-3" narrower)
