14 10.5" Bolt Locker
Anybody have any experience with Powertrax lockers? I'm looking to install one in my 14 bolt on the 79 to help it out a little bit when conditions deteriorate, and want to make sure it's decent and will hold up.

Re: 14 10.5" Bolt Locker
Not specifically in a 14bolt, but I have installed a few of them. They go in easily and hold up well. Be aware that it will drive a bit different, especially in wet or snowy weather. Caution anyone that you let drive it about this too.

Re: 14 10.5" Bolt Locker
Nothing wrong with the Powertrax and I have 3 LockRights myseld, but as far as full-float 14's go, that's the cheapest Detroit you can get which would make that a no-brainer.

Re: 14 10.5" Bolt Locker
Subscribed. I think mine has a gov-loc and want to get info as well. 1973. Still working good but I heard them called gov-bomb before.

Re: 14 10.5" Bolt Locker
The ones in the 14 bolt seem to be better than their smaller versions. I have seen them break too, but not nearly as often. Gov-loc

Re: 14 10.5" Bolt Locker
I'm pretty sure if you do have a Gov-Bomb in your FF 14 you will need to buy an open case to install any of the drop-in Lockers including the Detroit or Grizzly. Which means changing the case will require you to measure and possibly adjust the backlash on the ring gear as well. It will also require swapping out the carrier bearings which adds a different level of complication to the swap.

Re: 14 10.5" Bolt Locker
The aftermarket Eaton posi is different from the OEM Eaton Gov-Lok. The Gov-Lok, or Gov-Bomb as it is "affectionately" known uses gears, springs, and flyweights to apply pressure to the clutch packs. It is not truly a "locker" but a limited slip that functions as an open diff most of the team.
If you hammer on it alot and cause the mechanism to attempt to engage, you can strip gear teeth or otherwise cause it to come apart. It "blows up" like a bomb if you will. Google Images for 14 bolt Gov-Lok and enjoy the carnage. With that said, the 14 bolt version is at least the strongest version. The 12 bolt one pretty much grenades when you look at it funny.

Re: 14 10.5" Bolt Locker
Well it seems generally it looks favorable so, I do believe I'll order one up, sure would be nice to abolish the one wheel wonder. 10 year old balding tires + open diff, along with majority of the weight all sitting up front, just doesn't cut it when conditions worsen around here
 . Would do tires first but for the brand I'm after, I'll stick with a detroit for now

Re: 14 10.5" Bolt Locker
So to replace the Gov-Bomb I will need a carrier too? If so would an open carrier be a good choice and just buy the Detroit to go in it?
