Got it!!!! Very nice peice of work.

Ok guys, all of you guys doing the COD thing pay attention!

I am on the phone now (right ear actually) with Mike @ TA Performance. They show me being paid in full for my cover, but Fed Ex is wanting a COD fee of the cover price for me to get it. More than likely I will have to pay the COD fee and then have TA credit my card account, per Virginia @ TA Perf.


Make SURE you aren't paying for the cover twice!!!

Got mine earlier this week. $216 shipped to my door from UPS and that's including the stud kit and 2 bottles of Amsoil gear lube. I must say the installation instruction sheet looks nice too. Can't wait to finish up the other projects so I can have the shop install the 3.73s (Randy's Ring and Pinion) and the cover.

Yep, a first class piece of work. I'm glad that the guys on the board stepped up to the plate when the covers became available. Looks like TA has nearly sold 100 of them.

This might encourage others to make products for our third gens if they know that they will sell.

Got mine yesterday. Looks great! Hopefully (weather permitting) I will install it tomorrow.

My only regret...not getting the Amsoil gear lube to go with it.

Virginia was a sweetheart to me, I fill special. got mine ordered, she said a few days but I wouldn't hold it against her if it took a few weeks. Hope they except my different shipping adderess.

I didn't even know TA sold Amsoil......it's a good thing I already had some.

Got mine today, looks good. To bad there's no way to pull up the skirt and show off the new underware!

Hey, I've been watching this post for a while and had a question.
I have my stock borg warner 9 bolt and wanted to put it in my 1991 firebird along with a 383 HSR later. Would this cover strengthen my rear end enough to handle the added torque? I'm not looking at making it bullet proof, just enough to handle the 383 at the strip.

Simple answer, yes.

Basically you're taking a thin tin style plate cover and replacing it with something that's about the width of a quarter around the gasket area and made for strength. Also TA covers have the bearing supports. Heck just having the fill, level, and drain plugs is enough for me to buy one. :-)

Ok lets try this again. Pictures are not that great of quality and the underside is pretty rough still. Slight problem with the rear sway bar hitting the cover on hard bumps. Still havent dialed the panhard bar in exactly so I think that once that is done it will center the sway bar alittle better. A little concerned that I might have to grind some of the cover down on the driver side once I upgrade to the bigger rear sway. Right now the bar keeps sliding to the pass side after centered, causing it to bump the cover. Hopefully the pics will post and yall can get an idea of what to expect if installing on a lowered 3rd. Im not to concerned about it, it will only require mild modification to set-up. just some heads up. Installed eibachs pro kit. has poly bushings, etc...the works...

here you can see how the sway bar is getting close and off center. well more than it normally is.

I used gasket sealer as a temp because the sway bar hitting the cover was causing the gasket to shift and leak. once I get it set-up properly I will be removing it and installing the proper gasket.

You may need shorter endlinks on that swaybar also. When you lower the car the arms of the bar will tend to angle down which will affect the clearance at the diff. cover. Use endlinks that keep the arms of the swaybar level at ride height, and don't grind anything until you get the rear centered (that should help the walking problem with the swayabr.)

I agree

appreciate the advice. actually already did that. I can definately tell you that the panhard bar needs to be adjusted more. Its not that big of a problem for me right now, with the combination of the shorter endlinks, adjustable panhard, etc I know it will not be a problem to fix. I still have some tweekin to do, plus I want to load the trunk with my equipment and decide the final rear height...may need to lower it some more.
Was mainly posting to let some of the members that order the cover know that other variables need to be addressed. i.e. swaybar endlinks, lowering, etc...oh, and it is next to impossible to fill/ drain without either raising it or lifting the pass side.
I do want to thank yall for the replies and ideas.. this is why I love this group

Hey I'd really like to get one of those rearend covers for my car - I've been trying to find this. How do I go about getting one? Thanks for the info.

http://www.taperformance.com/rearend.htm

Thanks for the link- Pondriver. I am going to get the rear end cover but I also seen the "stud kit". Has anyone else got this and is it worth gettting? How much trouble is to change the carrier bearing caps? I have my rearend completely out of the car - so access is not a prob.


Also I am planning on using Mobil 75W-90 Synthetic Gear Oil - is this good or should I use the AMSOIL? I am also debating on changing the gear from 3.27 to 3.73 - but I have a stock TH700-R4 and stock 350 TPI. I have seen a few people running 3.73s but I don't know there rpm range. Anyway a lot of questions, hopefully you guys can help a fellow 3rd gen owner out. Thanks.

TA Performance - 480-922-6807, 9-Bolt Borg Warner Rear girdle TA PN: TA-1802. Order the stud kit with it...it's cheaper that way. The cover comes with directions - Don't do any thing untill you read the instructions...

I run the Mobil One 75W-90 oil in my Nine-Bolt with no problems. With a stock TPI I don't think you want to go to the 3.73 gears.
I have a highly modified TPI and run the 3.70 gears. If you plan on upgrading the intake system for better breathing than yes you might want to consider the 3.70/3.73 gears. Be sure to get the stud kit.

Thanks for the suggestions guys, yeah 1989GTATransAm, I am going to hold off on the gear swap, mainly because the engine wouldn't hold up too long.

That 58 mm TB you have - does it work well with your setup?
I know it wouldn't on a stock setup, just wondering.

I had a 52mm throttle body and changed over to the 58m throttle body. As of now I have not noticed any difference in power. However with my next round of upgrades I suspect it will help.

Dyno Don intalled the TA cover on the Trans Am this past weekend. I must say it is a quality kit. I can see where the stud upgrade is a big help in adding to the strength of the nine bolt. The studs replace the bolts that hold the bearing caps in place. This adds strength to that area. All in all I'm very pleased. Great cover and kit.

Hi guys I have had this cover on my car now for 4 months and no problems with the diff. I am running a super ram upper with an edlerbrock proflow lower on a 11.3 cr 406 possible 450 hp 2500 stall 3.23 gears bfg drag radials full weight 88gta. Note I was able to break the previous diff's bearing cap with the stock 305 no drag radials. I think this is a very good product. I recommend the studs and the amsoil as that is what "ta performance" recommends. Dave S.

Nitro-Nicky wants one kit.

Man, I would have thought this would have been somewhere else.
Does anyone know if I can still get one? I believe it would be a
no brainer with performance upgrades. Hope I'm not too late.

it should still be available, just cant necessarily get it for what those who got in on the GP got it for. Call TA or go to the website

add me to the list. any updates until when we can expect this?

Mad-Mic: I believe the GP is over. I was one of the original buyers and got mine 6-2005 so you're a little late. Good news is TA Performance should still have the cover so call them. I would recommend you buy the stud kit and 2 bottles or so of Amsoil if you're thinking of changing gears too. I plan on using one to break the rear in with (with posi additive), changing fluid and using the 2nd and another bottle of posi additive. It's the older formula so it appears they still recommend additive later if you get noise, but why do that and have to drain good Amsoil back out.

I think I would more than likely have to have one, please keep us updated
Thanks Les

The 9-bolt covers are now/still (and have been for a while) available from TA Performace: Rear End Girdles The covers (P/N: TA 1802) go for $159 a piece and the stud kits (P/N: TA 1802-SK) are $19.95 when purchased with a cover. Order 'em up folks, they're quality pieces, I've been very pleased with mine so far!! Huge thanks for all the hard work from board members and TA for getting these things produced!!!

-Paul

You can count me in. Just let me know when the payment comes due.

They are extremely nice peices.





The outside thickness on the gasket area is about the same as a quarter is wide, so extremely thick area for housing enforcement. You can also see the feet pads that tighten down to add preload for additional strength.

The payment is due whenever you call TA and order one Like fireturd350 said, they are VERY nice pieces!



-Paul

thanks man! my 9 bolt is coming out of my TA and into my Z with T-56 setup the 9 bolt now has 3.73's in it so no need for a gear change

i just had a 9-Bolt put in my 86 camaro from a trans-am after blowing my stock 10 bolt. Sounds like this cover is really important. What is it all about and why is it so important?

NEED INFO!

thanks,
Shred

The covers or "Girdles" as they are sometimes called help reinforce the bearing caps. The bearing cap is usually the first thing to blow up under stress, some what like the weakest link there. So with the extra strength added by the "Girdle" the rear assembly is up graded in strength. The girdle adds section quality to the bearing cap, and is strengthened by 20% (equal to or almost equal to 20%, I read the specs once and I think I remember the estimate to be close to or slightly over the 20%mark at the bearing cap). So any way one is adding strength to the rear assembly by adding the "Girdle." So if you were blowing up the 10 bolt rears, by adding a 9bolt (Which has bigger axels, and gears and beefier caps), and a bearing cap reinforcement cover this would lessen your chances by a huge percentage of breaking the new set-up.

I'M IN KEEP ME POSTED

Did you even bother to read this thread? These have been available for a long time, just call and order one...

Just received mine today with the stud kit. $197.00 Shipped to my door. This is truely a piece of art. It looks awesome.

to get it shipped to canada were i live will prob be closer to like $220. Lordco sells them for $250

Yay for friends with 60% discounts

I also like that their stud kit is made by ARP.

Installed mine a couple months ago with stud kit very nice piece!

what is a support cover/girdle and what are its benefits? im hoping to acquire a 9bolt in the next few days and dont understand the purpose or function of the cover/girdle.

This should answer your questions, z28crazy. Basically it's thicker and stronger than the tin peice so it makes the housing keep it shape much better. The preload feet help keep the caps in place better than the stock bolts. You can also get some ARP studs for $20 or so to replace your old cap bolts that will be high strength.

Add in the ability to fill, check, and drain your diff fluid without pulling the cover all the way off. It should be extremely handy especially when part stores can't find 9 bolt gaskets most of the time.

Hello all,

z28crazy check back through out this thread and there will be many places that describe the benefits of the 9Bolt "Girdle". Seven postings up from your post is a small explanation of one of the benefits of the Girdle/Support cover. When a rear assembly totally shreds it's usually the bearing caps that let go - sort of the weakest link at that point. The girdle with it's very beefy sectional thickness has feet/pads that rest against the bearing caps and add tension/ strength to the bearing caps to keep them in place. When the bearing caps let go it's a bad day. Even if the bearing caps just flex a little to much teeth on the ring, and or pinion may turn up missing, and or chipped - this is just one of the major benefits of the girdle to keep things in p[lace....many other benefits also.

It seems they can only be ordered by phone?
Can't find an email adress on the site?
I was wondering how much shipping will be to the Netherlands, Europe?

I looked too for you, I couldnt find it on the web page but they say they sell to Canadia or elsewhere. the email is taperf@aol.com. They have a little more info about oversea buyers in the Catalog on page 5
