so if I put a lockright in the rear, the gear ratio is determined by the locker itself, and I'd just have to match my front gearing to that?

Your gear ratio doesn't change when you put in a LockRight. It just replaces the side/spider gears....not the ring gear.

damnit guys, One more comment like that and the avatar changes!! I still have a Jeep hood, that's enough to let me into Jam right? lol
Sorry that was a very uncharacteristically passionate post, maybe there was an issue with mine, I remember it passing all of the set up tests fine. I just know it didn't matter if I was decelerating or accelerating the slightest bit it would lock. The only way I could avoid going into a herky jerky spaz attack making a turn at parking lot speeds was to accelerate straight, put the transmission in neutral and coast it. I hated that thing. Correct me if I am wrong but aren't there two types of Power-trax lockers? The lock-right and something else? One that allows a bit of wheel spin before locking up? in my eyes that's a bad idea offroad but may be better for the street.

so if I wanted to go from my stock 3.21 to say 3.73, I'd still have to change the ring gear in the rear and everything up front?

I wouldn't bother going to 3.73, if I know anything about Jeeping, you'll have 36" tires in less than a couple years. This is the point where you want to look ahead! And yes, ring and pinion front and rear.

Brandon, the other Powertrax locker was the No-Slip, which I had in the rear of my old XJ. That caused me a few problems so I modified it abit to work more like a LockRight (can't remember what I did to it).
Riles19, you are correct. You'd need new 3.73 gear sets for the front and rear.

If you're thinking 33's or bigger, you'll love 4.10 or higher ratio gearing. I have 4.56 on 35s in my XJ and it's awesome. I had 31s on my old rig with 4.56 gears and I could crawl like no one's business. If you regear one axle, you need to regear the other to match, unless you don't like having a transfer case. If you're going to regear, I'd recommend a Detroit instead of a lockright as they're very durable and predictable and you're going to have the carrier out anyway for the regear. Also, if you're thinking front locker, either selectable, Detroit or Truetrac, or whatever, decide before you regear, it's cheaper than doing the gear setup twice. See how fun this is? This is where it starts to get expensive

Here's your gear ratio chart: www.quadratec.com/jeep_knowledgebase/article-26.htmFind your stock gear ratio and tire diameter and you'll get the approximate RPM at a 65mph, IE highway speed. From there, find a number that's close to it for the desired tire size and find your gear ratio. In my case, you'll find that 4.56 gears with 35" tires puts me right in the green and on the better fuel mileage side. 4.88s would also work well.

My current one is perfect, unnoticeable, nary a click. Had another one in my old black ZJ that got broke a few times, it was clicky and annoying, randomly locking, etc. I think its the one in Darren's black TJ he's having trouble with, got passed around/sold as a used unit. Yes, I bought it used. It took a lot of messing around to get it setup so that it's happy. I'm no expert so to watch my questions and progress on here was probably painful for people that know what they are doing. To do it again, I'd buy new. Tech support from the manufacturer would have been awesome. Not something I will buy used again. Now that it is setup right. Barely any clicks heard at all in 2wd on the street and it locks like it should in 4x4. But mine is in the front. For Riles, considering where he lives (not the city), he could easily get away with a properly working lockright in the rear and not worry about it chirping the tires. But doesn't his axle come with a limited slip in it anyways? I would prefer the limited slip in the rear over a locker IF the Jeep is a daily driver. If so, leave it as is! I miss the LS in the back of mine. Enough traction to get you out of trouble but good predictable manners in the snow on pavement. My two cents, and I'm no expert on lockers.

Let me try again, you aren't getting it. replied to your pm. First - google image search the following, I don't think you have a handle on the components and their names. -lockrite locker -D44 carrier - Detroit or ARB locker - D44 gears Now armed with what these components look like, here are some facts: - The gear ratio is determined by the gears only. - lockrites install inside carriers - lockrites do not involve a gear setup (see how they go inside the carrier?) - full case locker such as Detroit and ARB do require a gear setup (see the spot for the gears to bolt to?) I hope this helps you out more than this morning.
