    Even a LS can be a handful in the snow when up front. If the clutches are tight, it can actually be worse because it never completely releases around a turn like an automatic locker could (...is designed to). Serious understeer can result when your hubs are locked. If you're driving on public roads in the snow, you're better off with an open front end until you can swing the money for a selectable type, like an Ox or air locker.

    Edit: I was judging my above statements on your location; I'm assuming a fair amount of your miles will be in 4wd in the snow. Moral of my story is, don't have buyer's regret about repairing your open front end.

    In the most general sense. Open diff's apply power to the wheel with the least amount of traction, which is why they behave well on pavement when making turns because the wheel on the inside will be making less revolutions than that of the wheel on the outside. A locker, will make sure neither wheel "slip" of lose power, so both must make equal revolutions, cause the tire on the inside of the turn to break lose from the pavement and fight steering in general making you track forward. A limited slip combines these two. It is essentially a locker with clutches that will slip under a certain amount of pressure, such as that of the inside wheel of a turn against pavement, however they should hold in the locked position under softer road conditions such as loose soil. This is why they are a good choice for a vehicle that see's road and offroad use.

    Indeed. If I was in the market, I'd rather have one of Daryl's "experienced" Power Locks!

    I believe they can be made too but it requires some creativity with the bearings. It's been discussed here before.

    The big advantage with the powr-loc is the four pinion spyder gears. Much stronger then a open diff. I believe the break on ratio's is 3.91 /3.92 or real close.
    Not many around that number for jeeps so easy to figure. mike

    Agreed...although I am very tempted by this powr lok deal - but kind of leaning to saving up for a selectable for the rear.

    How many bolts are on a D27 ring gear? I have seen info stating there are 10. The locker in the Ebay ad has 8 holes. Could it be for a D25? :confused:

    I have ox lockers front and back in my jeep and they are the greatest thing ever. Surprisingly I don’t really notice the front too much with the stock steering. Must be because of the skinny tires.

    My old notes that I have on Power Lok numbers shows a 22480X is originally for a '67-'68 Scout rear Dana 27. These are old notes and I don't remember where I got some of these numbers, so can't confirm.
    I know a Dana 25 has an 8 bolt ring gear, but think some Dana 27 axles also used 8 bolts. I know some Dana 27 axles do use 10 ring gear bolts. Can anyone confirm?
    The seller is Matt at Quarter Ton. I have bought a fair amount of parts from him, and he seems to know his stuff. I have always been very satisfied with what he sells. The '63 date knocks my Scout reference out the window!
    This still looks like quite a deal.

    FWIW, the power lok in the front of my jeep originally came in the rear of a 63 Scout.
    Be aware that if you put one of these in a Jeep with manual steering, your steering effort will be significantly increased when the hubs are locked in.

    I searched the forum and it appears that the general consensus is that the dana 25 has 8 ring gear bolts and the dana 27 has 10.
    The power locks being sold have 8 ring gear bolts, the proper count for a dana 25.
    Daryl, your still safe selling 27 power locks for $250

    Anyone please correct me if I'm wrong. I was about to pull the trigger on one until I did more research.

    Uh oh... if thats the case I am probably going to have to try to return them. I didn't even think to check the ring gear bolts. After doing some research I'm not totally convinced either way... I'll probably end up having to pull the cover.

    The "10" vs. "8" debate has raged for years. I note that Herm sells an adapter kit with a ring gear spacer that implies the ring gears are interchangeable to a certain extent. I'm seeing references from gear venders saying either 8 or 10 for both 25's & 27's.

    FWIW all the purported dana 27 powerlocks on ebay show 8 holes.

    Wonder if Daryl can chime him in terms of the ones he has. Guessing he has seen quite a few D27 ring gears over the years.

    I just read Howard's links on the subject of bolt count. Post #5 from our own McRuff back in 2004 seems to agree with my comments comments in post#33 here. It sounds like a Dana 27 can havve either 8 or 10 bolt ring gears.
    -Donny
    EDIT: I just checked a Model 27 axle and it has 8 bolts on the ring gear.
