what rear gears can i fit in my carrier???

its a 91 RS w/2.73 open gears....

what gears can I buy instead of having to buy a whole new rear end?????

can I get 3.42 or 3.73 posi???

thanks
Cody

 

look in summit they have gears for both carriers. you have a 10 bolt right? other wise you can get a posi while you are at it

 

oops did not catch you last part. you just get the carrier and gears you want. they will fit it is the same housing

 

so i have to buy the gears and carrier???

it can be any ratio as long as its 10 bolt and it comes with the correct carrier???

what am I looking at in the way of pricing???
around a 3.42 or 3.73 posi???

thanks a bundle...

 

i found this on jegs...

will this work on my car???

again i have a 91 RS w/2.73 open rear end...

and is this posi???

i don't know a lot about it, in case you couldnt tell

thanks a lot

 

The cheapest and best posi is the SLP take-off, their part # 64501T IIRC.... $99 www.slponline.com

There are lots of sources for gears; try these guys http://www.drivetrainspecialists.com...=28&cat=GM+7.5 I use them alot, they have good stuff, good prices, GM gears if you want them.

You'll need a complete gear install kit, and I also strongly recommend a crush sleeve eliminator.

go and look at that.....

if I purchase just that, is it going to be a posi 3.73???
will it fit my carrier????

install kits? what does that consist of and what might that cost??

I really don't know anything about this end of the car....

crush sleeve eliminator??? whats that? what does it do??

sorry for all the questions...
I appreciate all you are doing for me

thanks

No. Those are only a set of 3 series gears.

No. You have a 2 series carrier for 2.73 "2-series" gear sets. You will need a 3 series carrier, which the takeoff Z/T unit is, SLP P/N 64051T

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

If you install BOTH these parts, then you will have a 3.73 posi.

Install kits have all the necessary bearings and seals to install new gears and carriers into rearends. Search Jeg's, Summit, or here: http://www.drivetrainspecialists.com...=28&cat=GM+7.5 for the kit you need...for GM 7.5-7.625 ring gear for pricing.

Crush sleeves partially set the pinion depths..crush sleeve eliminators "eliminate" these. They are solid and don't crush => getting rid of most if not all of the pinion play in the housing=> stronger.

Spend a little time searching the key words you are looking to learn about. There is TON of info on this site to learn from.

thank you so much....
that is what i needed to know....

if i found for instance a rear end out of an RS 5spd w/ 3.42 gears but is an open rear.... can I put that slp unit in that and make it posi????

do I have to have the install kit then???? i'm on quite a budget....

is this a project that I should try to undertake??? i've heard people talking about backlash and things like that, and I don't know what they are talking about.....

whatcha think?

 

Yes, if the RS rear in question has 28-spline axles. 90-up ones will have those. 88-back will not (26 instead). 89, you'd have to count the splines to know for sure.

No, you don't "have to" do anything; but if you want it to last more than 100 miles, it's highly recommended. Or, look at it this way: If you're "on a budget", do you have the money to throw away on trashing a carrier, a set of gears, and maybe a pair of axles, and then buy the kit and do it a second time? If you don't have the money to do it right, then where are you going to find the money to do it over again, and possibly have to spend more fixing additional stuff that got tore up in addition to what you should have done right in the first place?

 

Honestly, if you're on a budget, it would be easier and sooo much cheaper to just buy a 3.42 or 3.73 posi rear from a '89-up disc car instead of putting all the parts together separately. You should be able to get one for around $300. Then it would just be a rear end swap....MUCH simpler.

go to a bone yard and look... but most places hate to pull all that crap apart and then have useless parts... IMO just find a rear from a 5 speed car and throw it in there... there is a guy here is Nashville that had one last week for like $150... but he sold it... you can find an entire rear for the same if not cheaper than getting the posi and gears new

 

ok thanks guys for all of your help
you have been very informative...

hopefully it will go smoothly and i'll try to let you know how it goes....

thanks
Cody
