      I have a 2003 wrangler sport, and was wondering if this would work in both the front and rear differentials and what other parts would I need for installation.

      • This locker is for Dana 44 differentials, with 30 spline axles. Your Jeep will have a Front Dana 30 differential with 27 spline axles, and depending on options you may have a Dana 35 differential with 27 spline axles, or Dana 44 rear differential with 30 spline axles. We have an article on axle identification at the link below to help you determine which axles are in your TJ. https://www.extremeterrain.com/wrangler-jeep-axle-identification.html

      I saw this LSD was able to support my 2014 wrangler sport on your site and i purchased it but now it shows only fitting a TJ wrangler. Will this support my vehicles dana 44 when I re gear to 5.13s and not go into limp mode after using a programmer?

      what is the difference between the performance series and pro series LSD

      • The Auburn Gear Performance Series LSD offers increased durability and performance in normal street use. The high bias cone clutch design of the Pro Series provides a higher torque and preload, making it the ultimate limited-slip differential for true performance.

      I'm looking to add this to my tj with dana44/4.10 gears, but the technical note says to use the 3.73:1 case for all tj's regardless of gearing. Is that true?

      • The Auburn Gear Performance Series LSD can be used in D44 cases with no c clips and a 3.93 and higher axle ratio.

          Review from Auburn Gear Dana 44 Performance Series LSD for 30 Spline Axles & 3.92 & Numerically Higher Gear Ratio (97-06 Jeep Wrangler TJ)

          Works good

          Installed with a fresh set of G2 4.88 gears so far assembly works great - good alternative to the factory traclock

          Review from Auburn Gear Dana 44 Performance Series LSD for 30 Spline Axles & 3.92 & Numerically Higher Gear Ratio (97-06 Jeep Wrangler TJ)

          Frustrated

          I ordered this LSD based on the heading this fit 3.92 and numerically higher gear ratio. We also installed 5.13 gears. Read the tech note!!!!! ON TJ AND JK YOU MUST USE THE 3.73 AND NUMERICALLY LOWER LSD CARRIER NO MATTER WHAT RATIO YOU ARE USING. THIS WAS CONFIRMED FROM AUBURN GEAR STAFF AS WELL. Auburn Gear also informed me that the 3/8" holes on the carrier flange for the ring gear will need to be drilled out to accept the larger 7/16" ring gear bolts that come stock and the 1/2" bolts for the aftermarket gears. Make sure you have a good drill bit and drill straight! As far as quality, everything else seems to be fine. We will put it to the test in the dirt!

          Review from Auburn Gear Dana 44 Pro Series LSD for 30 Spline Axles & 3.73 & Numerically Lower Gear Ratio (87-18 Jeep Wrangler YJ, TJ & JK)

          Great addition to my JK Drivetrain!!!

          I added this and it's made my jeep far better in the snow and mud. I can't imagine ever going without the limited slip differential. Extreme Terrain had the product to my door in 4 days from the time I ordered it. Thanks again Extreme Terrain look forward to buying more product upgrades in the future.
