Help choosing a locker for RWD?

Postby TBLBill [OP] » March 8th 2018, 3:15pm

Hi everybody. I'm trying to figure out what I could do about getting more traction from my open diff RWD, for winter driving and some minor offroading. Any recommendations? I don't know much about lockers/LSDs, but I'd like something without much of a learning curve or technique in case the girlfriend needs to use the van. Thanks for any help!

Here’s a link to purchase a used 3 series Torsen carrier. I have one in the rear on mine and love it. I love it so much I put one in the front too!
Torsen has no clutches to wear out, no special additives to use. Pretty much fail proof.
As with any traction system there will be a learning curve, with my jump from open to Torsen it acts like any limited slip and kicks out some under hard acceleration in slippery conditions. Very predictable.
Actually I think I have one laying about somewhere. I went new Detroit Truetrac
When I installed the MFactory Torsen in the front. Let me look and if you wanna go the Torsen route I can probably beat any price you can find online

Thanks for that! Let me know if you find it, I think I'd be interested. What's the install procedure like?

I have been in touch with my A/S brother Rinny. He was nice enough to host my front diff swap party and that is were a bunch of parts ended up spending the winter. I have been told that the Torsen I pulled out is in fact gathering dust at his place. wroditski was the OP on this one and so has first refusal on the sale. I still don't have the item in hand and there's a right proper blizzard thing happening outside right now so of course I'm gonna try to get out of work early and head east toward the blizzard warnings in RI/MASS with my twin torsens and talk Rinny into right seating an adventure

Also known as a "lunchbox locker". Save yourself the time, money and the headache and don't install one of these

Man, I've had 2 of those lunchboxes and had nothing but good things to say about them.

Put many miles on them with zero trouble, yeah, they are noisy in tight maneuvers in a parking lot but the low price and super easy 45 min driveway install make it worth that.

Don't get me wrong, I like my quiet/pretty much invisible G80 but it cost way more then my lunchbox. :D

No, I couldn't afford one at the time. I have a G80, got a really good deal on it. It was fully disassembled checked for cracking, then rebuilt with all brand new parts and checked for proper operation for 200 shipped.

Then I had the rearend fully rebuilt and the G80 installed for a touch over $500.

I don't have and personal experience in my own rigs, but the 3 lunch boxes I have installed in friends rigs come back a few months later get to do it all over again just to take it out.

So take my skepticism with a grain of salt...

Richmond has a “gentleman’s locker” out now. It’s a slightly less aggressive and far less noisy version of their esteemed #1935 locker. They for sure have their place but I spend most of my time on dry pavement so I went the expensive, seamless, invisible and expensive route with the Detroit Truetrac.
And just for transparency’s sake I wish to admit here and now that I was just rescued from a ditch miles from anywhere by a Jeep so ya even with power to all four wheels, once it’s gone-it’s gone!
