Getting a Detroit Locker. What if I Have a Thick Ring Gear?

Hey y'all,

I've got an '01 TJ with a Dana 44 rear. The previous owner had 4.56s installed (Precision Gear). He told me he needed a new carrier for the gears which makes sense because the Jeep originally had 3.73s. It seems Precision Gear offers thick and normal versions of their gears. I'd imagine he would've kept the old carrier if he'd opted for thick gears so I suspect I've got the "normal" gears.

I'd prefer not to drain the fluid just to check the thickness of the ring gear, but do I have a choice? The other question is if the Detroit is only offered in one configuration then I suppose I'll have no choice but to buy a new ring and pinion.

Thoughts?

Thanks,
Tommy

I've sent an e-mail to the orig. owner of the Jeep and hope to get some clarification from him.... In the meantime I'm open to suggestions.

why not just get lockrite or another type of lunch box locker. not saying detriots are bad ( i had one in my 14 bolt for years now its welded ) but it's easyer and cheaper to run a lunchbox and you get the same results. not trying to stop you and your choice, just giving you another option that im sure you all ready considered, jason.

Yes, a lunch box will get you a full locker, however, it doesn't have the strength of a full carrier Detriot Locker. The ones I've seen are also harsher and loader than the Detriot Locker (which is a soft locker). Weaker and noisier but also still good bang for the buck.

I thought the thick ring gears were for rubicon model 44's but I've been wrong before.

i totaly agree, they only other problem with a fullcase detriot is they are prone to shock load, another words if you break one side shaft you can wipe out the locker or the other side shaft. there was a huge write up on pirate about this, i never had a problem but i never broke a shaft, just the housing. so i cant coment on the fact that they can break like that, but i read and see ( on pirate ) peaple with one side broke and the locker in piece's or the other side let loose and broke.
i will try to dig up the thread and a side note i run a lockrite in the front 60 for 3 1/2 years now with 39's a heavy foot and no problems with it, jason.

Detroit

Why not just get a detroit for 3.73 and down 187s-16D? Then you can keep your thick gears, or you could go with an ected electric locker for not much more.

Wow, I didn't get an e-mail note that there were more replies to this. Hmm... Anyhoo....

I considered a lunchbox locker, but don't want one for the rear. It was rather annoying in my fullsize Bronco and I've heard it's worse in a short wheelbase TJ. So for me, the choice for the rear is a full Detroit or a full spool. Also, I've got a limited slip carrier. I'd have to get an open diff to install a lunchbox. If I'm going through that hassle, I'll opt for a full Detroit. A selectable locker for the rear just doesn't interest me, but thanks for the suggestion.

As it turns out, I heard from the orig. owner of my Jeep and he confirmed I've got a standard ring gear. However, I've since decided that with the purchase of a new house looming that I'd be better off saving some of that money. So I decided to just get a Lock Right for the front for now.
