any of you guys run this locker i am thinking about getting the for my rear third with 5.29 gears. and good or bad things about this setup

It is a limited slip unit (gear driven, torque sensing), not a locker. I have more information on my TrueTrac page...

I ran one up front for a while. If you had to run an LSD, as opposed to a real locker, this would be the one to run, but it doesn't fully lock up all time, so it has it's disadvantages.

Ran one for years in the back. Loved it on the road and in the snow. Somewhat hard to get to lock up until you get skilled with the parking brake and throttle.

Been running the "new and improve" (6 worm gears instead of 4) up front for almost 2 years now. As long as both wheels are on the ground, it feels like a locker. The only time I get wheel spin is when one is in the air, then just a little pressure on the brake takes care of that.

Never ran one in the rear, but I ran one back when I was IFS and I run one now that I have converted to a straight axle. I really like them for the front, as they are easy to steer, and help keep the birfields (or CV's if you have IFS) alive while running 35's.

cool thanks for the good info guys

why not get an aussie? everyone i know hates there limited slips. dont they wear out also b/c they have pads or something in them?

The TrueTrac uses gears, not clutch plates for it's limited slip action. It is not prone to wear and it doesn't require any special gear oil additives like the clutch type diffs do. I really liked mine (front) in snow, ice and mud. It has one advantage over lockers in that it can sense the torque to each wheel and adjust the torque bias before a wheel slips. For example when turning, an auto locker lets the outside wheel
"freewheel" since it is over-running the ring gear. So all the torqu goes to the inside tire until it slips at which point the outside wheel locks up and you get torque to both wheels (with the inside wheel slipping). With a torsen-type diff, like the TT, both wheels get torque in proportion to their traction. So as long as you don't overpower the tires and make both spin, you end up with both tires pulling and not slipping.

This really helps on off-camber situations where a locker tends to let it's tires slip to the downhill side. I recall a few times on a muddy sidehill having the Detroit-locked rear end slding down the slope but the TT front end was pulling straight ahead. So ended up crossing the slope with the front wheels pointing where I wanted to go and the rear end angled down slope with the tires churning along sideways sort of like this

well i was just wondering becuase i went to order an open 3rd member from randys today and they ran out of stock they told me the will take money off of a true trac 3rd with 5.29 gears for about 650
