I don't get it ..... I bought the SLP posi for my 91 firebird. I love it. But why was it so cheap when compared to Auborn posi units that are $400.

I know the basics of it. Same one as in new Z28's and Trans Am's. Its used only for 89 and up (28 spline axles and its carrier 3). My friend wants a posi and doesnt want to spend so much on it for his 87. And i told him unless he swaps out the axles to 28 spline hes SOL.

So what is the gain of spending the $300 more on the other units?

 

The SLP posis are take offs. This means that they are taken out of the new camaros while they put a better one back in. The difference is the one they put in is stronger and a better unit.

huh............years ago when i talked to slp about posi units they told me to go to reider racing for an auburn.........?

 

I have a 89 Bird, how much can I get the posi for?

 

They sell for $99, I believe, check www.summitracing.com and do a search.

 

No .. not summitracing. SLPONLINE and use model number 64501T.

Cool I have 100 buck to blow to make both wheels spin!

 

hah i had posi stock..

 

Really! sux to be me... I have to pay 100 bucks

 

going to cost another 100 to have someone install it unless you want to do it yourself. I had the gears all changed and i was without a depth setter, nor have the coordination to figure it all out. So, i let someone do it for me so i wouldnt be driving down the road, have a bolt fall out or something and have the rear end lock up. Thats my luck.

Better check your prices I cant find good shop that knows what their doing in NJ to do a gear swap for less than $500!

 

Are those good?? I am looking to upgrade my rearend on my 86 IROC. yes I saw i need to change to 28 spine.

 

Mitnick?

I'm seriously wanting to buy this unit.

 

Would an 89 firebird 305TBI have 28 spline axles?

 

This site from deadtread's post says it does

>I shouldnt have a issue with installing the gears. I whatched my Bro take apart a possi rear end and show me what all the **** in there does. I'll just get his help, hehe lucky me.


>who is Kevin and why does he need to be free?

 

Actually, it costed me 250 to get the posi and gears swapped out. Would be 100 if he didn't have to do the gears. Place is in south jersey near the betsy ross/ tocony palmyra bridges. If you ever need to know I'll give you the name of the place.

 

Yes Kevin Mitnick, he is out of jail but he is still on Probation. He was the Notorious computer Hacker.

 

Oh, I thought you were talking about Kevin Harvick.

 

I have an 87 and I want posi but I guess I dotn have a 28 spline axle. How much are axles?

 

You have other options. Powertrax costs more money, but you don't have to set-up the gears(probably can install yourself or much cheaper to have it done), won't have to install bearings, and it will work with the older 26 spline axles(no axle cost). After all that, the extra cost of the powertrax isn't much.

Most likely it won't. '89 was the x-over year so there's a slight chance it might. But my junkyard findings on late 89 model (May/June) turned up 26 splines.
