Reviews for EATON 19977-010 Performance 4 Pinion ELocker for 30 Spline Dana 44 with 3.73 & Numerically Lower Gear Ratio

I replaced the open diff in my '08 JKU Sahara with this locker two years ago. Engages and disengages smoothly. Has been wheeled hard a handful of times with no issues. Paired with Yukon chrome moly axel shafts and 4.88 gears on 35s. I have full confidence in this unit with this setup.

Good product

Mechanic got the locker installed, and it won't lock at below 20mph. Eaton was great to troubleshoot with the mechanic and say the would warrant the part. Quadratec was super easy to deal with on it, and got a replacement out the same day. I am still stuck paying the labor to swap the defective part. Confident it will he a great addition to the Jeep when we get it squared away.

Awesome diff. This is the way to go for anyone looking to regear and wheel their JK.

very happy with this locker so far.

Replaced broke Rubicon rear locker with the Eaton E-Locker a few months ago. Very pleased with its performance up to this point. Engages quickly and easily.

Working as expected. First one came with the back tab broken off. Quadratech was very easy to work with when getting it replaced. Maybe better packaging would help when shipping.
