I just put my order in for my 2012 Unlimited Sport and am pretty excited. I'm now starting the process of making my after-market shopping list and need some help in identifying what I should start with.

Due to money at the moment, I wasn't able to order the Limited-Slip differential. While I've been trying to get up to speed on the various tech (axles, housings, gears, lockers), I haven't seen anything about LSD capabilities.

Can anyone provide insight on what I'm missing? Is it assumed that these new upgrades include LSD (I would assume not)? If not, what should I be looking for (kits, etc.)?

Thanks in advance,

 

A lot of guys run the Detroit trutrac. It's an awesome LSD.

 

The JK has electronics that help with traction. Not a true limited slip functionality, but it helps. Next is a factory limited slip. And then the factory e-locker on rubicons (and an option on some non-rubis).

The factory limited uses clutches. This isn't the best design, as they will eventually wear out. The aftermarket limited to look at is the Detroit TrueTrac. It uses gears, not clutches, and is a great improvement over the factory unit. There are plenty of threads on the TT, a quick search will bring up lots of great feedback. Under $400 for the d30 version, somewhere around $500 for the d44 version.

Auto-lockers are an option, but are not your best bet in a daily driver that sees winter weather. Lunchboxes are cheap at $250 or so, and a Detroit would be $600-$700 I think?

Selectable lockers are the top of the food chain. They function as an open diff until you push a button, then the axle is fully locked. Figure $850+, depending on your choice, plus the air source and/or wiring/switches.

For a D30, the TrueTrac is by far my favorite choice.

 

Are they looked at for rear only or for front and rear?

 

Depends on your needs. Front and rear truetracs is a great combo for a daily driver that sees winter weather. If you spend a lot of time offroad in the rocks, full lockers in both ends may be a better choice.
