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? 1 answer

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

Would this work in a front Dana 44? 1 answer

If you Dana 44 front axle has 30 spline count, yes the Auburn Gear Performance Series LSD can be used in the front. Overall using a limited slip differential in the front is not recommended for a daily drive vehicle though.

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 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.

Word On The Trail

This company has always been the go-to site for good deals, good products, and service. I never have had problem with the products sold, even after several years of use. For example I have had the tire rack on my jeep from 2003 to now, I have brought a new jeep and the first thing I ordered was a new rack from them for my new jeep. Good product, good service, and the best prices. I use this company as a base line to compare other dealers with, and this company always wins out.
