I would like to put a locker of some kind in the rear of my F-150 4x4, and I am wondering which type would be best for all around use including street and icee roads in the PNW? A limited slip type or a detroit locker?
Thanks,
Bob
Detriot would be the worst and a selectable locker would be the best with a LSD a good compromise. Detriots cannot power both wheels are different speeds in a turn, it is 2wd same speed or 1wd with one coasting and they can be nasty at times especailly on slick pavement and they will increase your turning radius off road as well under power.
Obviously a selectable would be the best, an ARB or other air locker are great but run about 900 per axle. The detroit is built tough but can get squirly on ice or rain, other options are power trax 300$ and such which are a little cheaper and suposidly less squirly but not quite as solid as the 550$ detroit. Posi is an option but probably disapointing for you if you off road.
I think for an all around use, an LSD axle would probably the best, the next choice would be some kind of selectable locker. Lockers can be a bit tricky on icy roads.
I'm currently looking at an eaton one e-locker. I like the fact that you can engage and disengage it, they also have a limited slip version thats cheaper.
For a daily driver, get a Detroit True Trac LS. It's as close as you'll get to a locker, without the real drawbacks. It's all gear driven and it's fairly stout up to 35" tires.
ARB, ElecTrac's, Auburn ECTED's area all selectables and work well, but pricey. I have the 2 ARB's in my truck and they work real nice, just expensive.
For a DD or mostly street truck, stay away from the full lockers. You'll be more annoyed than anything.
best sort wo uld be selectable...best locker for price/function.... full case detroit. lunchbox lockers generally suck in the rear and are meant for front application. i personally run a spool and like it.
but you said street use so ill assume your truck isnt very "trail rig" so a lunchbox would be fine... Lockrite or Aussie

If I was hard core off road, I still would not use a spool as it will reduce manuverabilty and increase axle strain. I would use a selectable locker or a LSD or even a detriot before a spool. About the only good place for a spool is on a drag strip where you are running a straight line under power.

uhhhhhhhh ok, not really. my front and rear is welded and my manuverability never changed. actually if anything it was better b/c i could spin the rear and swing it around with the front sitting in one spot. tell me again, how often do you wheel? didn't think so!
dont lock up that 8.8 rear! you will grenade it from the inside out. just put a heavy duty limited slip and call it good

When I had my big truck (working on another) I had a minispool in the front and welded rear. Would not of changed them cause they worked well, never let me down and were the right price. Didn't notice any change in my manuvaerability off road. If anything it was better. On road, well once you got used to it all was good.
My 93 F-150 has a LSD out of an explorer (Trak-Lok), it was probably the best thing I've done for the truck, they're a pain on slick roads, and they work wonderfully on moderate trails, hard on clutches though especally when the tires hook up on dry asphalt.
Basicly, if its a DD just get a limited slip and you'll be fine.
