View Full Version : Rear sway bar - U-body kit in an A-body??

I've been looking at getting a rear sway bar for the Ciera from Addco. I was looking at getting one from a U-body though since it's bigger than A-body one, 1" versus 3/4". I know that U-bodies are supposed to use the same suspensions, but since the body is different I was wondering about fitment of a U-body kit onto an A-body. Looking at Addco's site you can see that they use different endlink kits. Does anyone have any insight into this??

I was under the impression that the rear axle is the same from the U body. That would lead me to believe the sway bar is the same shape....

1990-96 U bodies used A body rear axles as far as I know. 1997-present U bodies - beats the hell out of me, but I don't think they were A body pieces..

The U-body will work I was told. it is bigger then the A-body. However it maybe too much for the car? If you get the larger U-body rear you may need to get the addco front bar to balance everything out.

Does your Ciera have the engine cradle support brackets that come in the U-body and Eurosports? I think my 88 Ciera XC did but I forget. They are brackets that bolt to the steering rack and engine cradle giving it more support up front.

I should have updated this, but I talked to Addco about the differences in the swaybar. I asked specifically about the difference in the swaybar and the endlink kits. The told me that the swaybars are different besides the diameter. The 325(A-body) is 43.375" eye to eye compared to the 465(U-body) which is 39.5". Also the endlink kit for the 465 us 5/8" shorter than the one for the 325. He did say that the say bars are shaped exactly the same though and that the eye to eye measurement was the only difference. I haven't looked at my car yet to see if it looks like it will fit though. I'll post an update as to what my plans are after I measure everything. That is unless I find a good deal on an A-body bar, from a Celebrity perhaps. :D

This is what my subframe looks like, I don't remember any support brackets that looks like they could be bolted on.

Sorry to barge in here. I've meant to ask this question earlier, but always forgot.

Is it simpler to remove engine-tranny by taking the subframe with everything on it, rather than pulling the engine/tranny out through the top of the engine bay?

I will need to have the subframe exchanged, and the tranny... so I'd like to know which method is the easiest to go through with.

Bump: did you find anything else about this skalor?

Also, where the hell has Tuddi gone for the past two months: :(

I had wondered the same question as was raised a year or so back - whether I could get the U-van bar for my '89 Ciera. I'll have to measure and compare a few dimensions between the rear of my '92 U-van and my '89 Ciera. If anything, I can see the U-van having narrower rear control arm attaching points because the body itself is fibreglass with a steel underbelly. The mount points for the control arms may be farther in under the body. Like I said, I'll have to measure the two and find out for sure.

1997+ are all W body related..

Is there a Rear Sway Bar for the U body?

Yeah, Skalor listed the Addco part number for up at the start of the post. It's a 1" rear bar whereas the one for the A-cars is 3/4".

I know my Van does not have a Rear sway bar.. I am seriously considering getting the one listed...

Nevermind... I just ordered one... :)

Let me know how it fits, this is one of my mods I had planned.

I have to say now that I have been driving the Van for a good bit now( Been at least a couple thousand, and about 1500 Miles on the Tranny Rebuild )....

With the Monroe Matic Plus Struts up front, and the Moog Center Links bushings for the Sway bar, and the Energy suspension Bar to Control arm bushings, the 16 " Bonneville Alloys and the 225-60-16 Toyo Tires( Soon to be a stickier Summitomo ) The van actually handles pretty good for a van... I have been so busy with picking stuff up and hauling stuff around that I always take the Van.. Went with a friend to pick up a ford 3.8 today...

Anyhow, I decided to go ahead and get the rear bar for the van.... The van does need help in the rear and I would like to have the handling a little more solid and stable... I am hopeful that the kit will make the installation a bit painless and provide that little extra I am looking for..

Somewhere along the line the rear will receive Variable Rate Cargo Coils, and new Monroe Max Air Shocks.. By the time I am done this should be a very well mannered van with a fun to drive feel..

I will get Pics and the Like for you when i get the bar... Shipping will most likely be very slow tho...

Anybody else see those Monroe Sensa-Trac load adjusting shock absorbers? Part number is 58427. They're available through Rock auto for less than $80 for the pair. The application listing says they'll work for X-bodies, A-bodies (would be especially useful for wagons, of course), and '90-'96 U-vans. I'm going to order a pair, it's just a matter of WHEN.

Looks good. I look forward to installation pics and a write up of what kind of gains you got.

Refresh my memory, have you upgraded the front sway?

First I have to say I tried to install the bar.... all I can say for Today is * EPIC FAIL *.... I really need an Angle Drill to get in there to drill the hole... This is going to be fun... But it won't beat me...

The Front sway on the van is a 26mm, largest one they made.. But I used Moog Center Link bushings and Energy Suspension Bar to Control Arm Bushings... As well as the 225-60-16 tires... Van handles better as it is and what I consider quite good for a van...

I'll have to get that angle drill to simplify my life and installation... Cry.... I really wanted to take it for a spin with the bar....

Time for an update... The bar is installed...

First I had to mock everything up to figure out where to drill the bracket bolt hole... Had to go through the other side too... What a PITA...

Next was to hang the U bolts on the solid rear axle, then add the brackets and bushings to the bar and install finger tight..

Then I installed the bushings( end links ) and snugged them up

From that point I made sure everything where where I needed it to be and tightened everything down..

Van in the Air...LOL

Had to use a right angle to be able to drill the holes...

Initial thought... The Rear bar was a good improvement for the van... It did give the van that extra handling I felt that it should have had from the factory... But being that the bar is as large as the front bar, the back end is now tight and can get you into some trouble if you were to push too hard... After all its a van and still a tad top heavy... But I am pleased to say the least, the van does feel more sure footed and better in lane change maneuvers... With the new bar its not hard to find the limits of a 400 treadwear, H rated 225 60 R 16 tire... Sure makes the tires work.... But the van has become a better handling vehicle and if I had to do it again I would... Total shipped to my door was $150ish and worth it...

Bump x 2. I'm also wanting to know the same thing. How did you incorporate your cherry picker in the process Skalor? I'm just looking to pull the motor and transmission. Did you replace the bushings on the subframe before you reinstalled everything?
