I'm thinking about replacing my Detroit soft locker in my Moser 9" with a strong posi. I tired of how the locker throws the car around in the turns. What do you guys recommend? I know Rich Krause likes the Eaton unit with 800 lb springs; is that available for a 9" application?

 

I went with a True Trac posi for my 31 spline setup. We built mine at work, and the guys who build these all the time suggested it to me. I dont know if Eaton makes one, otherwise I probably would have one as we are a Eaton dealer. So my guess would be they dont make one.

Best write up I have ever seen.

 

I have a Tractec locker. It's strong but very noisy!

 

i've got the ford posi with trac-loc springs and the 4 pin version.i had a locker and my other rear and i know what you're saying about them. you never know when its going to lock or unlock in the corners huh?

 

Thanks for the feedback guys! My local shop, Pro Gear in San Diego, is recommending a Trac-lock. About $800 to rebuild my existing 3rd member. My other option would be to buy a new 3rd member with the posi (about $1,150) and sell my existing 3rd member with the soft locker in it.

 

Crzhrs, Thanks for the link to ring-pinion...a lot of good information. I find it interesting that they don't list the Zexel Torsen T-2.

 

i broke my true trac for my 9".. So i went locker... I don't seem to have all the issue's that most complain about w/ theirs.. i think its very predictable..

 

I bought a Trac-loc from Randy's Ring & Pinion this morning. They beef it up by replacing the stock cast "hat" with a billet piece. Also decided to step up to a Currie 9+ housing a 6161 aluminum oversized pinion support. These parts may be over kill for my application but the new housing saved me the core charge cost of $82, helping to offset some of the addition cost. Great tech line at Randy's! When I swap it out I'll have a 9" 3rd member with the locker, 3.50 gears, 31 spline, 1330 yoke up for sale if anyone is interested. It's in great shape if you like lockers!
