    My 2008 jku has a factory non rubicon 44 with 4:10.1 gear set in the rear what limited slip will work?4

    • Thank you for your question! The Auburn Gear Performance Series LSD - 30 Spline - Dana 44 - 3.92 & Higher Gear Ratio (87-17 Wrangler YJ, TJ & JK) would be a great option for your 2008 JKU Model Wrangler for the rear Dana 44 axle.

    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.

    I have 5.13 Yukon gears in a 2008 jku Dana 44. Is this the best option for a daily driven vehicle that sees occasional use on trails?Would a true trac be better?

    • The Auburn Gear Performance Series LSD - 30 Spline - Dana 44 would be the most cost effective setup for you if you're doing very light trails. However, if you want something that can handle quite a bit more, you would want to look at the True Trac.

    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 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 Pro-Series LSD - 30 Spline - Dana 44 - 3.73 & 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.
