Limited Slip Differential
Hello Everyone,
Just wanted to ask you guys if anyone on here has used an LSD on their V6. I plan on purchasing one from summit racing. The company Eaton makes one that would fit our cars. It's 439 bucks so before i go through i just wanted someone elses thoughts.

I have never used one but that pro trac system I saw on HP TV was cool. It will fit / go into any rear end, no spool chang needed. Its is $4-500 but anyone can do it in a few hr in the drive way. It a neat unit as when turning it will act like a stock peg leg rear, but in a straight line both will lock.
My self I like that the best. Even a limited slip spool can be dangerour in bad weather and a spool n axel change isn't fun or easy.
If that one is similar, the price is about right and worth it.
Post a link to it plz.

MakeitQuick92RS yes, an LSD will help traction issues and for the v8 crowd, the 3.8's respond quite well to having traction, the best would be a spool or a locker, but you lose streetability, so go with a zexel or perhaps a nice protrax.

My personal votes go for a zexel or auburn limited slip unit for general street, protrax locker if you're looking for sheer straight line performance. There are other suspension modifications to help keep the wheels squarely attached to the pavement, though. Tubular LCAs + relocation brackets, adjustable torque arm (MAJOR), decent springs, good shocks, etc etc...

Now that I look at how much you're looking to pay for that Eaton, I think it's neccessary to point out you could probably walk away from a junkyard with a 3.23 posi disc brake rear and master cylinder for ~200, and still have enough cash to buy nice tubular LCAs and brackets...

edit: SInce you have the newer rear, try looking up at one of the SLP take offs
edit: I caint find teh take offs now, maybe there aren't anymore.

2.73's and a v6 motor = No No

So a limited-slip from a z28 won't bolt to the 3.42 gears?

the ZT unit works good. it has, like, worm gears that run the length, well width i guess, of the carrier to the side gears. with a load on it, the worm gears will force the side gear out, to the side of the unit, therefore, locking it. that's my understanding of it anyways, someone correct me if i'm wrong. there's no way to put ZT insides into a open carrier. good luck replacing the guts to get posi. i could be wrong but i've never heard of being able to do that except to go, basically, mini spool...aka welded carrier. reshimming it wasn't really hard, just a bit of a pain and time consuming but not necessarily difficult.

as posted above, the pro trac system on HP TV just replaces the 4 gears in the center of the carrier. i didnt know if zexel was the same or not. but you told me what i needed, thanks. im gonna look into it.

Do they make a mini-spool or spool for the V6 10 bolt rearends? I got an open V6 10 bolt rear (from an 88 SC) and I want to experiment with a locked rear hehe. I looked for a mini-spool online but I only see them for 28 and 30 spline. The V6 rear in 88 is different spline count right? (not sure, but I think 26 spline?). Anyone know?

i think it was 88 or before when they changed the 7.5" 10 bolts to 28 spline axles. someone else can jump in on that one. but, the rear end for the v6 is the same otherwise, even if you do have 26 spline axles, you can get a set of 28s to put in it, just make sure that they are from the same width rear end and you'll have no problems. for that matter, why not just weld your open carrier?? that be a lot easier.

I did some more looking and found that both Richmond Gear and Summit Racing Equipment make mini-spools for the 26 spline 10 bolt rearends. I'll probably go with the Richmond part for $89, but gonna make sure to count the splines in the axles before ordering since 88/89 was a switchover year.
