Sammy is right. True lockers are not very street friendly. I've got Lock-Rights in the front and rear of my CJ-5 Jeep. You can't even drive on the street with the front diff engaged. You have to make sure the front is disengaged. Besides the drive train bind, it's very hard to turn with a front locker. On the street an air locker is far better for the front. Or if you have manual locking hubs like on my jeep, you have to have the front "unlocked."

I run 36 inch tall TLS bias ply Super Swampers and have a lot of other mods. Even rear lockers don't behave very well on the street but lockers are absolutely THE way to go in the dirt and mud. They are absolutely amazing when you have the front and rears both engaged in the dirt or woods. But that kind of grip can force you to upgrade the rest of the drive train, or you will quickly find yourself breaking axles, or at a minimum, popping u-joints regularly. When tires can't slip, the weakest other part will!

Besides Sammy's observation about the "chirp" of the inside tire when going around a corner, the clicking sound when turning, and noise when they engage and disengage, sometimes with my CJ the whole back axle (with the rear of the truck) will try to jump to the side about six inches or so when you accelerate or especially when you suddenly let up on the throttle. Jumps out when you get on it, jumps in when you let up. You get used to that, but passengers can be really spooked. And you can expect that quirk even when running at high speed in the dirt.

Again, damn good in the dirt and mud, (or on the drag strip) but usually a bad idea on the street. And, I doubt there is anything out there yet that will work with our gears and axles.
