1.0 Worked good but can't get parts.

After not being able to get parts and seeing the ware on the engagement ramp and the price of there parts, I no longer recommend Eaton E-lockers or any Eaton products. I was able to rewind the electric magnet and smooth down the ramp to get it working, but for how long I don't know.

Q: Curious what I need for lockers on my 2012 JK Unlimited; running 2.5" on 35s; 3:73 gearing 6 speed manual. Front and rear & any special tooling? Is this something a novice could perform well (aka - good instructions, etc and approximate cost to complete (no labor cost) Answer this question

A: Hello The E-Lockers are pretty easy to install compared to other units like the ARB or Ected. Here are a couple of links for the units you would need for your JK. I would install new carrier bearings while you are there. The front unit does take a different bearing to install also I have them listed in the links.

Q: I currently have these lockers F&R in my 94 ZJ with 4.56 gears, and 30 spline Chromo axles, they work amazing! The issue I have is that the LP D30 has smoked two gear sets, so I am looking at swapping in a HP D30 but want to make sure the locker is the same before pulling the trigger on buying the new gears as I know those will be different. Answer this question

A: Hello Yes it does take the same locker for the high pinion. Thanks
