Difference between 14 ff open and govlock

[la_blazer82]

Sorry for the ignorance, new to straight axles. Am thinking of changing out the rear 10 bolt for a 3/4 ton 14 bolt. What's the difference between a opened and a govlocked axle?

govlocks are factory installed lockers...notorious for blowing up in 10bolts... stronger in 14 bolts.

Just asking -- 14 bolt govlocked axle is available and wondering whether it's easy to change out gearing and add a locker (i.e. Detroit). Or whether it costs more than an open 14 bolt

I'd look for an open one, it will be easier to swap gears and put a detroit (or whatever locker) in it.

I recommend you get one with an open carrier and install a detroit. The Gov lock is ok, but it recquires a lot more wheel spin to activate (approx. 100 rpm). The detroit will lock as soon as one tire slips.

I have the 14bff with the factory Gov-Loc, and i wish i had an open carrier to install the Detroit, the Gov-Loc to me doesn't seem to really do much, maybe helps alittle, but not real noticable, it could also need rebuilt too though, but either way, wished i had a little different setup...Get the one with the open carrier. /forums/images/graemlins/waytogo.gif

OH and the other thing is you can't install a Detroit into a Gov-Loc carrier.

To break it down a little more, govlocs have 3 side gears and have a clutch pack. The open 14bolt diffs have 4 side gears. The detroit requires the 4 side gear case to be installed.
