Wow... so much misinformation I gotta speak up.
The D30A holds an RD100 just fine. Works like a champ and beefs up the center section by adding 2 extra pinion gears to your stock set up. Works better than the TT because you can turn it OFF when you don't need it, limiting wear on your oh so weak CV's. Lockers don't wear out carrier bearings.... Trac Tec makes a TT for the 8.25 now. They're great, I used to have one. If cost is an issue, grab one and enjoy it, especially if you're not wheeling very hard. They work great on wet and snowy roads... (Someone tell Trac Tec I just said nice things about them). The only issue with the True Trac and the 8.25 (unless they've fixed it) is that you have to grind your c-clips to get em back into the carrier. Not a big deal.
As for our stuff.... if you can afford it, it's the best. PowerTrax isn't a true locker. It's a drop in. They just replace the spider gears. Yes, they're easy, but they DO shorten the life of some drive train components. If I remember correctly, the TT is actually cheaper, too. The TT or a Detroit are full carriers and add strength without the selectablity. Both work great...much as I'd like to say other wise. The ARB is a full carrier, adds extra pinion gears for strength and is fully selectable. Strengthens the Diff on or off and increases life of your shafts and othe parts because of the afore mentioned on/off option.
Hmm. Too many acronyms and too much company acquisitions to keep things clear for us insurance salesman!
You said: "PowerTrax isn't a true locker. It's a drop in."
I'm wondering if those are two separate points. I thought Powertrax is a true locker because it locks both wheels, regarless of whether it's a drop in or not. The drop in means it's not any stronger than stock, since we're using the stock carrier. Right?
You said: "Trac Tec makes a TT for the 8.25 now."
this is where I'm confused. Tractech is now owned by Eaton, who also owns Detroit Lockers and also Richmond I think. The TT is Truetrac? If so, this is NOT a locker, as per their web site where they refer to it as a "gear type limited slip differential."
I wanted to buy a true locker for the rear on a budget. Perhaps wrongfully so, I didn't consider anything that was not a true locker since I have a trac-loc now that actually works well EXCEPT WHEN I lift a wheel off the ground. So it seemed to me that I'd have to either spend big bucks for air or electronic lockers, or spend slightly less for a mechanical locker that requires professional installation like a Detroit Locker, or get the budget minded Truetrax lunchbox Powertrax setup.
As for wear, unless it's switchable, all lockers will add wear/stress to the drivetrain and tires, right? I'm always very carefull now about applying throttle when turning, especially slow turns, so I'll continue to do so.
Please, feel free to correct any gross misconceptions I may have above. Again, my goal was to be able to keep moving forward, slowly, while I've got one wheel off the ground. It's my understanding that nothing will really do that but a locker. And I mean REALLY do it. Yes, I've managed to keep moving with my trac-loc, even have it on video, there was a lot of wheel spin on the part of that lifted tire. Whereas when I've watched Rubicons and other locked Jeeps do that, you couldn't tell that wheel was off the ground because it spun at the same speed as the wheel on the ground. THAT'S what I'm after (ON A BUDGET).
(Hopefully that long post didn't come off as preachy. It's more of a regurgitation of what I've learned over the last few weeks and I'm looking for confirmation. Please don't pee on my recently-ordered-but-not-yet-installed Powertrax!
)
I'm going to start a new thread on how to drive with them, and also how/when and under what circumstances will the Jeep be able to keep moving or not. (ie, 2 wheels diaganol off ground, go or no go?)
