Spool or Lunchbox

Okay I am asking for a co-worker on this one, He saw me on this site(busted) and just bought a used 2011 JK 2door. He wants a locker in the rear of the jeep but only has a limited budget around 500.

He wanted to know whether a Spool or a Auto/Lunchbox is better for the short wheelbase. Drives aout 80% on road and 20% off here in West Texas. And knowing him from the last couple vehicles he isn't going to be easy on the throttle.

I saw the other articles on here and directed him to them as well as the JP articles, but couldn't make up his mind.

Whats the JKO consensus?

I wouldn't to run a spool 80% on the street if it was given to me. It's a miserable idea, eats up tires, hard on components, kills turning radius.

Can you run a spool on the street? Sure. But it's a terrible idea.

A buddy of mine has a YJ that is constantly locked up in the rear and he acts like it's fine, but I've ridden in his rig and the ride sucks, especially on turns. My JK wouldn't unlock in the rear one time so I drove it back home. There is NO way I would want to drive around on the street that way all the time!

That was my opnion, but hey he's too lazy to get his own ID and ask and those were his options cept for the bacon. Told him that it had to be on ther.

He's more concerned with budget but has the typical I need it now syndrome.

That's not something you want to reset the gears to install, hate it, pay for a new locker and pay to have the gears reset again. But hey, it's not my money.

I know. Any opinion on the Yukon Grizzly? Its on the upper end of the locker budget but I think I may be able to convince him if its a good product. The Detroit is the only locker I have any real experience with and its a little out of range.

The detroit isn't that much more then a grizzly $590 vs $550. If hes on a budget why not throw an aussie up front for $300 and worry about getting a rear when he regears instead of paying for labor twice.

Just asked him and the answer is "We are dumb and didn't think about it."

Honesty didn't really consider it as a viable option to get a ton of traction on the trail. I know anything is better than open, but figured rear would be the best to do first, so I guess I misguided him a little.

A couple options here:

Throw in a Spartan locker (lunchbox locker) and run it. This is friendlier on the budget.

Or

Throw in a Detroit or Grizzly, have the gears set-up and be much more confident in it.

Tell him to get his own username on here, the more the merrier!

Plus, wouldn't he already have a LS in the rear? Maybe not, but if I was going to dig into my diff and go to the trouble of installing something it sure as hell wouldn't be a LS!

Aussie is great on a budget.

Most do not have an LSD. The brake lock differential you may be thinking of is just the abs/traction control firing an open differential to power the other tire

I love the brake lock differential in my '08. It's good enough that I have moved a locker way down my list of future mods. Makes it hard to really call it open diff, it's so much better than a true open. My .02

Aussie is the route I am taking once my tax return comes in . I dont see the need to pay an extra 6-700 bucks for a selectable in the front. For the rear definitely but.....I have yet to hear anything bad about the Aussie besides the clicking when turned full lock. I think I can deal with that.

Ran a spool in my TJ for about 6 months. Worst idea ever for a DD rig especially with a short wheelbase. Front left tire would lift off the ground on sharp left turns and it destroyed my tires. It even scared me off road a few times. I will never run a spool in the rear of a short wheelbase rig again on or off road.

It isn't bad until you try to climb something and need the traction of both front wheels. Then it sucks. It is also a lot harder on parts since you have to get the wheels spinning for it to work a lot of times.

what would be the benefit of getting a yukon grizzly vs say an aussie. They are both auto, so why pay the exta 200 for the grizzly? Not saying its not worth it, I am just curious as to what would make one auto better than the next

I would tell him LSD.

Most will complain that the locker changes the feel of the Jeep and makes to much noise. Spool won't have the noise but will be harder on the tire and feel.

My build sheet states that I have a "anti-spin differential rear axle"

I assume this mean limited slip correct?

If you are only doing one at a time start with the front when you lock just the rear and you are trying to climb something the rear will tend to push you off line. With just the front locked you will be able to climb better with out having the rear push you off line.

Strength! The aussie uses the stock weaker carrier. With the grizzly or the detroit you get a stronger carrier. Not that this will happen to everyone but it can happen

You can't compare the strength of a full case locker vs. replacing the spider gears and relying on the stock case for it's strength. Plus, time and time again the lunchbox style wear out due to street use. They don't like street use. Plus, time and time again, I see the stock carriers lose spec which directly affects the lunchbox operation.
