    did civilian trucks with the 14bff have the detroit locker as an option, or was the gov-lock the only option? I know in the older Eaton axle the Detroit was an option (G86 No-Spin), and I know about th CUCV's, but unsure about the civvy 14.
    Just curious because I am looking at a 14 bolt, seller has advertised with factory locker and 4.10 gears. I have pics of the carrier and its definitely an open carrier with some type of locker inside. factory detroit or ???
    thanks in advance

    Haven't heard of or seen any Civy 14's w/Detroits. I am fairly sure it was only a Military option. Wish they did come in Civy's.

    thanks for the pic, you actually posted it in a previous post of mine about discerning between a gov-lock and open carrier, and I used it as a reference point. I will try and link up some pics of the axle this time.

    My 1991 V3500 Silverado Crew Cab 4X4 came from the factory with a 14 Bolt Full Floater and Detroit Locker. The G80 Locking differential RPO code is in the glove box. Plus when I opened the diff cover, to change the gear oil, it was plainly obvious as well.

    G80 is a gov bomb.

    I've never seen a factory detroit in a 14 bolt civvy truck.

    What else are you looking for, it's been pretty well established that they only came "factory" in military vehicles.

    Your pics are too dark and I cant tell if it has a locker. If it does youll be able ot see a spring through the hole on the left and right, otherwise youll see a gear.

    sorry, I was just interested to see if anyone had any factual info that they were or were not an option , not "I think" or "I've heard of" responses (although I do appreciate those who chimed in, thanks again).

    To me it looks like an open carrier with a locker in it. I can easily distinguish that it is not a gov lock carrier, by looking at the pics above by stallion85 (thanks again also).
    I do not see a spring in the holes in the carrier (and there are holes, the bright shiny patches). But also, I do not see spider gears. I just see smooth metal, which says to me "locker." My Eaton H052 with a Detroit in it is the same way, there are no springs visible, its just smooth metal, and I also have another open Eaton carrier that I can easily see the spiders through.

    I am unfamiliar with the 14 bolt and just wanted to make sure it is what is advertised. Thanks again for all the help and sorry to those I have offended.

    I have been to several different web sites that claim to have accurate RPO code descriptions, and so far I have found three that say the G80 code is a locking differential, and two others that say it is a limited slip differential. Who do you believe? I know mine has a locker in it because I removed the diff cover. How it got there is anybodys guess.

    The Gov-Lock is called a locker by the factory. A G80 is a gov-lock.

    I know that GM used NoSpins ( Detriot Lockers ) in the larger trucks and had a RPO code for them and it is not the G80 that GM uses for the Eaton Gov-Loc's and other posi units .
    Has anyone ever checked to see what RPO code GM used for the CUCV's that had D/L's in them ???? I am not saying that this will settle anyones question on this post but it might enlighten us on the RPO code for the D/L's if GM was accurate enough.
    Note: I have been seriuos about GM trucks since the eighties and I have never seen a truck that was not a military or industrial application that came with a Detriot . I am not saying that it never happened but I have not seen one either . GM did call several posi's / limited slips / or what ever "locking differentials" it was a marketing slogan for anything not open diff .

    I think the diff in my truck came from a junkyard. When I first bought the truck, I noticed some chalk markings on the diff that had the final drive ratio with a $180 price written on it...just like a junkyard would do. I suspect the original diff was blown up by a previous owner, and they went to a junkyard to get another one. Then had a detroit put into it while they where at it.

    Perhaps its the same as it used to be...the '66 C/20 that my Eaton H052 came from had "No-Spin Diff" listed on the option sticker and was RPO G86. It also had a neat little sticker by the rear window that indicated the truck had a No-Spin from the factory. I have a pic of this same sticker from Yukon Jack's K20.
    There is also a G87 "Maximum Traction" RPO, but I *think* that its for a dana 60 rear power-lock.
