Message:
Guys I have 2001 RC Dodge Dakota Sport+, and its got the 3.92 corprate 9.25 rear, Its open-trac though so only one tire (right side) pulls, what would it take to convert this to a posi-trac type rear where it would be limited slip? Will the R/T Trac-loc unit work in this? Guys if anyone has the answer please reply with part numbers and discriptions of everything I will need! Im gonna have a local speed shop install them but Im gonna buy everything firsthand myself. Please include everything for a posi unit install. Also I have rear antilock breaks will changing this to posi mess with that? Thank You!
Seth

Funny thing is that I am about to do the same thing to my 2000 SLT 4.7 RC. I believe and I hope someone more educated in the matter (CW) chimes in, but the trac-loc unit should just replace the existing spider gear cluster you currently have. I have read numerous directions on the net about the install and it seems very simple. The cross pin and clips should be able to be reused. I am replacing my clips just because of the milage on the truck. Search the web for (9.25 lsd install) and you should come up with some useful info. Good luck and please if anyone has any specific info please post away:)

No-Slip Traction System For REAR Axle With Open Differential
Axle Type: CHRYSLER 9.25-Inch Ring Gear Axle With 31-Spline Count & 12-Bolt Cover
Note: Fits Models With Round Differential Cover Only
With the Powertrax No-Slip Traction System, you can unleash your performance vehicle's maximum power or give your Truck or SUV the ability to get you just about anywhere. Whether you want the added safety of high traction for everyday street use or extreme traction for the most demanding applications, the No-Slip advantage is just a simple upgrade away. Precision synchronization control provides exceptionally smooth and quiet operation. There are no friction clutches to wear out and no special lubricants required. Easily converts your open, limited slip, or locking differential for superior traction output.
Synchronization Mechanism Eliminates Ratcheting Sound Typical Of Locking Differentials!
Enables a 2WD Vehicle To Outperform a 4WD Vehicle In Poor Traction Conditions!
Takes 6,000 to 36,000 ft-lbs of Torque! Much Stronger Than The Axles!
Most Models Installed In Less Than One Hour!
Maximum Power To Both Wheels Off The Line And In High G Turns!
Installation: The Powertrax No-Slip Traction System can be easily installed in your existing differential case without requiring special tools or setup equipment. Only basic mechanical skills are required. The Installation Guide provides easy to follow, step-by-step, fully illustrated instructions to help make the installation straightforward. Be sure to follow all instructions and heed all precautions. The ease of installation will vary depending on your differential type. Review the Installation Guide before starting to become comfortable with the procedure and to insure a successful installation.
Tech Notes: Limited slip and open differentials require different part numbers. It is very important to know which type differential you have in order to get the correct part!
Retail Price: $497.19
Your Low Price: $429.95
Usually ships within 24 to 48 hours.
---
That's the one you need. NOTE! It will make a ratchet sound when you are turning or driving slightly off from perfectly straight. Not to worry (sounds like the click click click when going uphill on a roller coaster!)
This is by far the best rear locker available that is still streetable!

I just bought the sure grip (auburn gear)
limited slip through the friendly dodge dealer..
looks like I'm gonna have to pull the gears
and everything to install it, but this setup is the
same as the R/T's, and its pretty much the
same price as the trak lok, unless you
swindle a deal ; )
so, yes, you can convert to an R/T limited slip.

the R/T's sure grip isn't as stout a differential as the Trac-Lok. My 00 orginally had an open rear w/ 3.55 gears. At 30k I put in my Trac-Lok and its so stiff at times the inside tire chirps around corners. I got mine from my half brother for cheap since he ran a dealership but they aren't too pricey I dont think. Gotta get the chrome diff cover!

4.7RC,
Did you have to remove the Ring gear to do the install? If so was there any shimming involved or is that just for the pinion gear?
Thanks,

yes you have to remove the gears, I reused the orginal 3.55's w/ 30k miles on them and no noise and now i've got 45k. The Trac-Lok is a tough differential. I did put all new seals in it since I had the rear out.
