92 rs have a 10 bolt or what.......and if so, is 75 bucks a good price for some used 3.73s? seen the pic , they are in good condition

 

A '92 RS would be a 10 bolt with either 2.73 or 3.08 with a V-8.
The 3.73's would need to be for a 2 series carrier.

 

2 series eh? ok cool deal, ill just buy them new then. keep it on the safe side that way i KNOW they will work, thanks...
you know a site where i can get the gears for the speedo by any chance?????????

 

3.73 gears are usually series 3 carrier. You can get a thick 3.73 gear to fit into a series 2 carrier or use a special spacer for the regular gears.

There are 3 different 10 bolts. Third gen use 7.5/7.625". There is also 8.5" and a 8.2" 10 bolts but they were made years before the third gen.

 

so will they work or not lol. is mine a 2 series or what..im lost

 

what series your carrier is depends on what gears it was originally equipped with....if you know that any drive line vendors should be able to tell you what carrier it has.....also, almost every f-body ever made has a 10-bolt rear. except for those crazy 9-bolt guys...but they didnt put those in 92's

 

they came with 2.73's

 

Whatever you do, DON'T buy the special gears to put 3-series gears on a 2-series carrier. You will end up with a situation where you are stuck with a 2-series carrier for the rest of the life of those gears. They work fine, as far as working goes, no problems there; they just limit your future options to near zero. Much smarter to either buy a 3-series carrier and put it in at the same time, which is no extra work or expense other than the carrier itself; or, if your 2-series is already posi and works good, get a spacer. The SLP posi for $99 is the way to go if you want to buy one, those gears will bolt right up to it.

The sum of $75 plus the SLP posi is less than the price of the speical gears. A spacer is about $60, again, cheaper than the special gears.

 

you saying i can get posi traction for 100 bucks?!? anyway, so i should go ahead and buy the 3.73s 3 series?

 

Yes. http://www.slponline.com/view_produc...TNUMBER=64501T

Yes.

 

If the gears are in good condition, pick them up along with the SLP posi, i just installed 3.73s and the SLP take off posi in my 90 RS and they really woke up the L03.

 

ok so what else do i need, ....the slp posi, ..the 3.73s, and a spacer? whats the spacer called so i know what exactly to ask for when i order it. sorry for being a pain guys, ..i just like to be positive on stuff before i place orders and start projects

 

no, the 3.73 gears you are picking up are for a 3 series carrier, the SLP posi unit is a 3 series carrier (3.23+). All you need now is the installation kit ( www.summitracing.com ) and your ready to have them installed (no spacer needed, it is only needed if u are trying to put 3 series gears in a 2 series carrier)

 

You need a kit (Ratech 309TK IIRC), and mabe a pair of axle bearings & seals, and a couple of quarts of Mobil 1 gear lube, and a high-quality 6-point 5/16" box wrench. Don't try to fudge the last one. You'll see what I mean.

 

i thought i had a 2 series carrier? i thought thats what the 92 rs came with, dammit im lost again

 

i know how you feel, i didnt understand all this stuff when i first started either......

The SLP posi is a 3 series carrier and replaces your 2 series carrier.....now all you need is 3 series gears, an installation kit (i used Ratech's Deluxe installation kit part number RAT-3001K at summitracing.com, $120 it includes everything needed to install new gears and posi + wheel bearings and seals that should be changed anyways because of the age of our cars), and some gear oil (i used RedLine's synthetic oil, part number RED-57904, it is about $8 a quart but you only need 2 quarts). I also bought a new Differential cover from SLP when i bought the posi since the old one was all rusted, it also has a drain plug so that i dont have to drop the cover in order to change the oil.......Hope this all helps

Also, dont expect to do the installation yourself, so you have to factor in the cost of labor, i paid $300 to have mine installed, i guess it really depends on where you live and the shop that is doing it

 

ok gotcha, ...back in the understanding zone. going to get the money order now, ....i have some friends that said they would install the gears and all for about 125 bucks, guess i lucked out huh

 

yeah, you really lucked out, but im from CA and every quote i got was from $450-750, then i meet this guy from the boards that lives in the town i go to school in and he was able to do it in the shop he worked at. So i lucked out too i guess

 

FYI, you can get the Ratech bearing kit for $90 + shipping from www.thunderracing.com. I just attempted to replace my 3.08 open diff with a used 3.42 posi from eBay, but it was a disaster To make a long story short, I ended up putting the new bearings on my old gears since the 3.42s simply would not run without massive noise.
