Lockers lock the differential together giving you actual 4x4. Jeeps although are classified as 4x4, are really only 4x2, meaning one front and one rear wheel have power applied. If you are offroading or drive in areas where extra traction is needed lockers might be for you.

This is a widely believed statement, but not really true. In an open differential both wheels are receiving the same amount of torque that is being required to turn the one with the least resistance. That means that while on a road, that both wheels are pushing you along equally, but when one starts loosing traction, so does the other, so the amount of torque stays equal. That is why when you lift one wheel off the ground, there is no torque (or very little) applied to the opposite wheel.

It is true that a locker ties both right and left axles together, so if one looses traction, there is still full torque supplied to the opposite one.
If you have a stock Dana 35, don't put a locker in it. It's not strong enough.

I have a Dana 30 and Dana 44. Was going to regear to 4.56 but wasn't sure if I should put lockers. Was thinking if I do, then I was going to put Aussie Lockers.

I can write more tonight but for now, here's an article on lockers I wrote years ago, you may find it helpful... What? Why do I need a locker? I thought I had 4X4!

An Aussie would be a great choice for the front axle but lunchbox lockers like the Aussie, Lockright, and EZ-Locker or very poorly behaved when installed into the rear axle. When in the rear, most lunchbox lockers bang, lurch, etc. when on paved street surfaces.

The only lunchbox locker that is somewhat well behaved in the rear axle is the No-Slip from Powertrax. It's about $100 more than an Aussie but for the rear, it'd be a much better choice. Better yet would be a full case locker like a Detroit Locker (extremely well behaved) or selectable locker like an ARB Air Locker or Eaton E-Locker.

You would just need 1 locker per axle. So if you want a locker up front it's just one.

Two axles on your jeep, front and back. Pumpkin in middle of each axle are the ring/pinion gears. The two lockers is inserted in the differential. This is the same place as diff oil area, so if you need or want to. Change your diff oil and see gears.

You should ask yourself whether you need 0, 1, or 2. Chances are you may not actually need or use lockers.

TruScrew? I think someone was yanking your chain when they gave you that name.

Here are the lockers & LSDs they do make... Eaton Differentials

Eaton's Detroit Truetrac is a very good limited slip differential. Which is not even close to being a locker. Lockers are much better offroad, limited slip differentials are more for street use.

Consider a Detroit truetrac limited slip for the rear. The D35 can handle it and it is more street friendly than an auto locker and like an auto locker, just install and drive.

Does anyone know of a good (reputable) youtube video that demonstrates how to install an e locker? I have a pretty good idea on how to do it. I want to see how they set backlash and preload.
