Opinions on Zexel Torsen Locking Diffs? (Clutchless Posi) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey Gang,

I was wondering if any of you have had experience or have opinions on the zexel torsen limited slip units? They are the clutchless posi's that come in the new LS1 camaro's and firebirds and even some hummers. I am considering getting one my pickup but would like to know how streetable they are or how well they work if anyone has had experience with them? SLPonline.com has them for $99.99 and they will work with my new Sonoma Pickup. I may also get one for the 70 C10 when those clutches are toast. What do you guys think?

They don't have them for the 12 bolt rearends only 10 bolt. I just called them.

But it should work in my Sonoma

As far as the inner workings are, do you this would be a good working unit? Reliable? good-working? Quiet? Streetable like a clutch-type posi?

It sounds like a good unit. The power capacity would have to be pretty decent since they put them in camaros and the firebirds probably good up to 400 horse i would guess. I don't know of anybody running them in trucks or with loads to haul.

Doesn't the army Hummer use torsen LSDs?

I put one in my IROC.. transplanted the whole rear end from a 2000 SS. Im quite happy with it. Locks up great when launching.

I had an Auburn Pro Posi unit in my old rear end and the Torsen is jsut as good. Can't beat the price of those SLP take out units either!

ts71281 · 12-15-2003, 04:05 PM

So you're saying the SLP ones are used take-outs? I thought they were NEW, never installed........AM I missing something here?

**lock** · 12-15-2003, 08:41 PM

Well they sell a few types I believe. The $99 ones are "new" in the sense that they were installed by GM and then taken out and replaced by heavy duty ones by SLP in their signature cars. They havent seen road use... so new but installed or used but never driven? lol

not a fan, they are great for traction but noisy. but if you dont mind it, they are great!!!! and they do hold up to alot!

I wouldn't think they would hum or whine as long as the backlash is set correctly. I saw 1 service bulletin on them about a squeak they tend to make but by adding GM Posi fluid to the unit it quiets the worm gears down. I am going to have this unit installed professionally so the backlash should be ok. I don't think my 4cyl 2.2's going to rip the guts out of it too easy

If santa brings me one this year I'll let you guys know how I like it. Out to the local parking lot to see how she cuts donuts
