    In preparation for My winter project (14 Bolt swap) I was re-reading the magazine article about lockers/spools/ltd slips again....

    I know that that "classic" solution for a 14FF is to just throw a Detroit in it and be done with it, but the article mentioned that if you are willing to put up with the chirping tires anyway, maybe it would be just as good to go with a "full-time locked" rearend like you get with a spool.

    The concern I have about the Detroit is the manners on the street. Supposedly, the best way to drive with one is to coast around corners so that the diff is open. If you touch the gas in a turn the diff will engage and cause a sort of 'swaying' effect. Coasting through corners is not a very good habit in the first place, so I'd rather not HAVE to do it to compensate for strange differential behavior.

    SO:

    Question #1: Is there such a thing as a spool for the 14Bolt FF?

    Question #2: Anyone have concerns about using a spool over a Detroit, or any personal BTDT wisdom to share?

    Detroit. The only reason to go to a spool is for the lack of money.
    As far as the manners of the Detroit vs the spool, they are going to be the same. At least with the locker you "can" go through a turn without tire chirp. The spool, will churp the tires no matter what.
    and if your worried about it pushing out on you in the middle of a turn then you just keep you foot on the gas steady all the way through the turn.
    My opinion is that spools are best left to drag racers.

    I don't know of any spools available for the 14 FF. I do think that the spool would have a little better manners in certain emergency-type situations, but with a detroit you will quickly get used to the way it drives and its not a big deal. Besides, once you get the hang of it, changing lanes with the gas pedal is a good way to impress a date.

    I welded my 14...very predictable and it has proved to be reliable as well. The cool thing is the components inside the 14 are all so overbuilt so welding it up doesn't seem to affect longevity.

    And then there are the Lincoln Locker people like that bozo Rene. [​IMG] They are in a league of their own. [​IMG]

    Having experienced both...........I have a comment.

    Rene is not a bozo!!! [​IMG][​IMG][​IMG]

    Anyway, I have ridden in tRustyK5 with the Lincoln Locker, seemed to have excellent manners. Can't comment on how it behaves day in and day out, but can comment on the Detroit, since I have one in my 14B (and my D60). They take a week or so to get used to, but after that they are fine. The occasional loud BANG is somewhat disconcerting when it first happens to ya, but it happens very rarely and never when you are actually driving it, at least in my case. It only did the BANG thing when I was backing up with the wheels turned. Much like with ANY posi/locker/spool, pulling out on a hard left or right hand turn under power in the rain could be hazardous to your directional stability..............but that again is true of all traction aids in the rear (don't go there, ARB boys [​IMG]). Rene has had his welded rear for almost a year now (right?) and it has held up, a Detroit is a proven performer, so either way sounds good. BOTH have peculiarities. That is what you get when you get GUARANTEED traction.

    the massive backlash the detroit gives you is a negative. i would/will trade my detroit for a spool in a heartbeat. the coast through corners is in town only, on the highway the detroit is invisible USUALLY, every once in a while it sounds like your transmission fell out. if i had an old 14bolt i would weld the spiders like tRustyK5 does, would never weld the sides to the case like most do.

    i have used both, i had a spool in my 12 bolt and when i swapped in a 14bolt i put in a detroit. i liked the spool better, like someone else said it was more predictable. it was easier around corners, still harsher than open, but there was no popping and jarring if you pressed the pedal on a corner. the wheels just kinda skidded instead of rolled.

    The only time mine really bangs is occasionally just after getting off the highway. Quite infrequent, though, its more of a Lock Right characteristic. Were I to start over, I would consider the lincoln locker aproach.

    My Lock Rights are almost totally transparent.

    I think this may have to do with how you drive it.
