      So this locker will be a direct fit for my 2007 Wrangler X with 3.21 gears.

      I have a 15 sahara jeep with 373 gears but plan on putting 488 gears in it. Will it fit with the 488 gears. It says its for 06 but mine is a 44 with 30 spline. I want electric lockers in front and back.

      • These are only up to 06 and will not fit with a 15.

      Will this Auburn Ected Dana 44 3.92 locker fit in the stock rear D44 carrier/housing on a 2005 TJ Unlimited (LJ)? It comes with the 3.73 stock and planning to go up to 5.13 or 5.38, but I'm concerned that lockers won't fit the stock carrier. Thanks!

      • This locker would be able to work with the stock differential housing on your 2005 Unlimited.

      I'm building a 2013 Wrangler Sport and installing 4.88 gears. I first bought an Auburn LSD diff for Dana 44 3.92 and up carrier and it didn't fit. I notice you don't list this model for JK. Do you offer something comparable to this that will fit my need?

      • This Auburn Gear Ected Max-Locker Differential is rated for 3.73 & Lower Gear Ratio, meaning it would not be compatible with your JK model and 4.88 gears. We offer the Auburn Gear Pro Series Limited Slip here: https://www.extremeterrain.com/auburn-gear-pro-series-jk-tj-yj-542082.html for 3.92 gears and up that should work with your sport model!

          Work Great With modifications. VOIDS WARRANTY

          Wouldn't fit my 2014 jk with out modifying it. Had to drill out the holes to make the ring gear fit. I'm sure I void the warranty, but it works great.

          More than i expected

          I've been a shade tree mechanic for 30 plus years but was my first locker install, it was a bit of a challenge but with the help of a local machine shop, I was good to go. The best part of this locker is the limited slip, i seldom need to lock in because of the great traction it supplies all the time. I've been running it for 2 years now, still works perfect

          Not too bad of install

          Shipping was prompt and the instructions were decent. I was a mechanic years ago so installing wasn't a problem and the fit and end results were good. Overall this was a easy job but just a few things: Extreme Terrain suggested synthetic gear oil and Auburn Gear instructions say the unit wasn't designed to use synthetic oil. Also the bearing/cup part numbers told to use from Auburn were not correct. I did have to drill out the ring gear bolt holes on the carrier to accommodate the 1/2" bolts used for the ring gear. Still the fit used was great I have almost the exact backlash after the install as the factory before. Thanks

          Auburn electric Locker

          Great and awesome for the first three year but once the clutch Locker was wore out the electric Locker didn't work anymore it had too much slack in it to stay engaged so now when I Engage The Locker it pops and let's go

          Auburn E-Locker

          I think it's an excellent product. I have used it to climb and descend many a Desert trail. Crawled through many a sandy wash and never been stuck ( except once when I got a large boulder wedged under the front end of my Jeep ) while going through a rocky ravine. Still, I was able to back up and off the boulder. Not possible if I had not had the Auburn E-Locker. I recommend it for any one who is looking to upgrade their off road vehicle.
