Tru-Tracs are good for 750rwhp. I have done many on the Gen 1-2. I use the Quaife for power levels above that. There is tunable posi available now up to 1200hp that is another option.

How much is the TruTrack with 3.33 gears for a Gen3?
I know there are 3.42 gears out there but I had heard they were not as strong and made for lesser HP cars. Any thoughts?
Received the unit back today. The total including shipping back to me and a new 3.07 R&P installed, strap hit and 4 quarts of syn oil so I can change it later was $1832.38. The packaging was terrific with everything labeled perfectly. I just unwrapped it all, going to fill rear and install in a few hours. I will say this, if thier installation is anything like their EXCELLENT PROFESSIONAL packaging, I will be thrilled. The unit is painted, cleaned, has a nice metal Unitrax tag on it and anyhow I am a picky a@@ guy and for me this sure looks professional all the way. I will report after I install it later and start to easily put the miles on it as the directions tell me to. Gary

I got the same reply form Devon, "you should get new gears". Oh well, another $200 I didn't want to spend, but rather be safe than broke again
They charged me $300 for a new Spicer Super 44 3.07 7/16" Ring and Pinion. Seems a bit expensive unless I am missing something here, but overall price still seems very reasonable.
I was too cheap to get new gears and went wth "low mileage" takeouts. I am a bit worried about Dan Cragin's remarks. I hope this setup lasts for more than a couple fo runs.

LOL you and me both. I told him I might run NOS very soon on top of my Roe, port the heads and such so I want it to be able to hanbdle 1000 RWHP, so anyhow Devin knows and assured me it would be fine. He literally said he NEVER saw one come back yet, so let's see. I got it under the car, had a bitch of a time getting it between the frame rails (it was a BITCH getting out that way too!) and ended up bench pressing it into place. I will finish it tomorrow as today I was tired and depressed about some shit with my business. Tomorrow will prove to be a better day, so the Viper will be on the road again-yeah!

Dan, can you please post where you pot your information that they are only good for 750 RWHP? I will send a PM for you to post here as I would like full disclosure for our members, including me. I'd like to know if you had them break, any personal experience that you can share that is negative to support it incuding who did the installation would be appreciated. TY in advance, Gary
I did call Dan from DC as well as Devin from Unitrax. Devin called bullshit (my words, not his) on this and Dan recanted that he had no evidence that there is a 750 RWHP limit and will amend his post. Both also indicated they never saw a failure in a Truetrac. Dan further went on to say he thinks the Quaife is stronger and the 750 RWPH imit is just his number and has no basis for that number at all.
Rear is in, I did a 25 minute easy drive and let it cool for 2 hours. I then drove it another 25 minute drive and let it cool overnight, but no noise and anxious to start using it next week after I put a few hundred easy miles to break in the R&P gears and center section. If you guys are pulling the rear out, take the safety hoops off if you have them installed, but the halfshafts you can leave in. Just make sure the hoops do not hit the black rear brake line towards the front of the car which is easy to do if you are installing on your garage floor like I did. I BREAT THE SNOT out of my car, so I will update after the beating begins in a few weeks, but thus far Unitrax truetrac scores with me on service and overall price hands down and I am a picky bitch.
Running some decent HP, maybe 700ish at the wheels and might go higher as my street beater. My rear seems to be acting up with 35K miles on it but certainly still drivable. I will jack up to be sure that is the cause, but I am 98%+ certain it is and I already tried adding more friction modifier but noise on turns tells me my center section is having better days-lol. That said, I see there is the Quaife and the Truetrac option. The Truetrac is $1,000 and the Quaife is $1600, but I was told by a vendor that neither one breaks, but Quaife gives you a lifetime warranty verses a 1 year Truetrac warranty. I want to keep my stock rear ratio too and a stocker has done me well, but I am going to keep adding addl power, but since this is my driver car I will keep it below 1000 HP as I do not want to do the motor all over. Anyhow please give thoughts on rear only if you have experience and I really want to hear from the Truerac guys as there are plenty of folks that will vouch for Quaife
Thanks to Mike 99 RT/10 too for offering to loan me a rear on the public forum. Although I did immediately PM him a big thank you, this is a gesture that gives me a little more faith in mankind and my thank you is public too It is another good Alley real world experience I have seen many times of an offer of assistance.
I have a used True Trac sitting in my garage, is anyone interested?
