Tru Trac in a 12 bolt? Has anyone tried this set up? I see they now have it for the 33 spline axles as well. From what I gather the Tru Trac is durable and is good for the Auto cross/ Road Race crowd and not to bad for the occasional 1/4 mile pass.
I'm putting a 415ci LS2 in my car, I currently have the an Eaton posi in my Moser 12 bolt but I do Autocross and 1/4 mile duty. So any input would be greatly appreciated.

My car has an Eaton Posi, I'm very happy with how it held. I just discovered O have a gear swap problem with this carrier unit. I have a 4 series carrier in my Moser with a 3.73 gear, on my current set up I need to step down to a 3.42 gear. The problem is the 3.73 gear is the lowest you can go with this carrier 
Anyone want to trade a 4 series for a 3 series Eaton posi?

I was thinking about going to this Tru Trac. Its suppost to be pretty strong from what I've heard. I wish there was someone who has had it and tried it in a true test i.e. 5500-6000 rpm launches on ET Streets or ET Drags. If it can hold up to that then I'd get it.
Well, I have one in my Cutlass. 8.5 axle with 3.73 gears. 5k RPM clutch dumps at the strip with M/T drag radials dead hooking. I could not like the True-Trac more. The car is my daily driver, 15k miles over the past year since the axle install, zero problems. I wish all aftermarket parts worked this well.
