Powr Lok vs Truetrac

Well, I gotta get a diff for my dana 30 front axle because of the ratio change. I've been thinkin'(ouch, painfull) I might as well spend the extra money now and just get a limited slip. I'm kinda leaning towards a Powr Lok(Power Lock, Power Loc, whatever...) because it is rebuildable. The Detroit Truetrac looks good too but is it rebuildable? I'm always looking down the road at stuff like this. I dont want something that I will just have to throw out in 5 to 10 years and get another(like an Auburn unit).

 

The trutrac from what I understand does not need to be rebuilt. It does not have any clutchs but instead some kind of a gear setup that does the slip limiting.

 

I've heard a lot of good about the Trutrac, but, I've also read that they will wear and that they can only reconditioned by the manufacturer. I think I read that in JP. Personally I prefer the Powerlok. There is a reason why it costs so much more than the Trutrac. Reliability and the ability to rebuild it yourself. I looked for a used Powerlok for my D30 for about 6 months, then bit the bullet and bought one new from West Coast Differentials http://www.differentials.com/ Good luck.

 

Everybody has their own opinions about which locker, limited slip is best for them and nobody is wrong in their opinions. It's just what works best for them. With that said, I like the Truetrac. I put one in the front of my YJ's Dana 30 and loved it. I've also been running one in the rear of my '99 XJ (Ford 9-inch) for 45K miles with 33s and it's as tight as the day I put it in. By modulating the brake a bit you can get them to nearly lock up, but they have a lot of civility on the street. There's no clutches to wear out over time and as long as you're not overloading the gears inside the unit (like 38+ sized tires for the D30) it's gonna last as long as your ring and pinion will. Honestly, I don't think the perfromance of a PowerLock and especially a TracLock come close to matching it, but do your research and buy the one you're most comfortable with.
