I was looking to start the process of redoing the entire suspension of my 95 SS , including steering linkage. I was poking around eBay and ran across a rebuild kit from a company called American Undercar . I was wondering if anybody had ever heard of it and/or if it was any good. It seems really inexpensive, which I'm wary of as you tend to get what you pay for. They say it's made in the USA and what-not... If this is bunk are there any kits out there that folks might recommend? I'd actually prefer something a little more performance oriented than direct factory replacement, but I'm not really sure where to start. Thanks!

With those particular Suspension/steering pieces there really is no "performance oriented" replacement. The only difference in these parts from brand to brand is QUALITY. Your best quality part is only 3 that I would recommend and those are Proforged, Moog or AC Delco only.

Lots of cheap kits out there, but they are just that and you get what you pay for. Be Leary of their ad on eBay as they say it's "Moog part numbers" but doubt they are Moog parts. That could be a little deceiving. A lot of manufactures share the same numbers Moog does.

Whether you're doing this yourself or paying someone, you don't want to do this again anytime soon. Spend a little more money and get quality parts...IMHO

Edit - on second thought, there are Solid Billet adjuster sleeves from Proforged and Hotchkis but not really a performance increase.

Thanks for the input! I figured this was TOO good of a deal. I'm basically rebuilding this car from the ground up so I definitely want each area I attack to be done correctly and with high quality parts.

Yeah, what 4doorSS said. I looked at the link you provided and it states that the ball joints are oversized. That most likely means they are the 5/8th inch ones used on the later 9C1. I got my Moog parts from Rock Auto and used the discount.

Sounds like you are considering a Complete FE rebuild...good call by you. I'm partial to Eibach Springs and bilstein shocks and is what I chose. but heard good things about the hotchkis parts.

gbhs brought up a very good point and 1 I missed in their add on "oversized" BJ's. The manufacturers make a Stand 9/16" BJ and a 5/8" BJ but there is also an "oversized" 9/16" BJ sold for use in cars that the Lower Control Arm hole has opened up "just enough" that the Press In fit of the BJ is not as tight. So these are made so you can keep your stock 9/16" arms that have maybe had the BJ's replaced a few times and have opened up.

This is my install when doing a 5/8" conversion that talks about some of those details but also shares some improvements in parts (even to Moog parts) that you could employ on your rebuild.

http://www.impalassforum.com/vBulletin/17-suspension/351769-my-5-8-bj-install-pics-tips-part-s.html

It may even give you some ideas on other parts you want to add to your order. The only difference in parts for you may be the Lower BJ's and Control Arms....pretty much everything else is the same.

You could also save a little money and buy new Bushings and just rebuild the Arms yourself assuming they are solid. Really not hard to do with the correct tools which can be borrowed from most parts places. Good Luck with your re-build.

Concur 100% - "I'm wary of as you tend to get what you pay for."

The ad is at least right in that a quality-grade complete setup normally runs $300+ for all those parts. The low price for that kit "made me look" further, and I stopped after looking up just one part. A legitimate centerlink is at least $50 (and an ACDelco is $70):

Not near enough left over for even a 1/3 what's remaining. lol

You would do well to pour over the dozens (maybe hundreds?) of past threads and stickies on various coil options as there's way too much history, buyer experience and specs than what anyone can recount all at once here again. There's also a good deal of intel in here on what shocks and coils behave well together - and don't. It depends 100% on what you're after for looks-performance-comfort... I admit never hearing of Hotchkis shocks before your post. For that money (or less) I have fallen in love with Bilstein for my past 4 cars in a row. A used setup of Konis I got (0% front - 20% rear) have been treating me right on my new FWB. Others favor HAL QA1, and some are satisfied with more economical Monroe Severe Service, and either the single or double valved KYB (one design is way too weak for stiff coils - I don't recall which).

Plan on spending countless hours researching the threads here on suspension and steering. You'll get more info that way as most seasoned members have left the forum and although you're getting good advice, the "meat and potatoes" you're looking for is already here buried in older threads. Long story short, don't worry about upgrading the steering components. Just get quality replacement parts. The only caveat to that would be the steering shaft as some use an upgraded component from a different build. Research it and you'll see. Suspension upgrading is different. LOTS of things to figure out there and lots of different paths to potentially pursue. They're all interrelated to one another so develop a good plan and stick with one consistent proven recipe. There is no "one size fits all" solution.

You also have the option of using urethane bushings. They will make the car transmit more road "information" through the chassis. They are a performance upgrade, because they are stiffer, but you may find the ride slightly harsher. They do keep the suspension parts from deflecting as much under pressure, thus the handling will be more predictable.


You will require an alignment if you put drop springs on the car. To get you to the shop, you can remove .030" of shim per 1/2 of drop on each stack. Measure the rim to fender distance before and after installing the springs, and remember to tighten the bushings AFTER putting the weight of the car on the suspension.

Thanks for all the great advice, folks. My Summit cart has grown a bit, but I switched out the Hotchkis stuff for Bilstein and Eibach which was actually a bit less expensive. Which frees me up to maybe grab some upper and lowers for the rear... It truly never ends. I could have just saved up and bought a clean, lower mileage 96 SS when it came time but noooo-oooooo. Had to go for the basketcase where literally every single piece of the car needs to be replaced lol!

Isn't it great? My project started with replacing a fender and headlight. Then I discovered this site. I'm like others here. Old Coot mentioned that his parts were piling up. I'm there too. The only thing my wife has said is "You're running out of room to store it." That was after five deliveries in one week. I love her. Might be time to buy her another gun.:laugh:
Keep us informed on your project.

Buy the lo-miler too! You can engage in an open relationship with both and freely swap parts and upgrades between them - of course as far as the wife is concerned ALWAYS for 'Safety'. And like John Hurt said in the movie, "Why build one when you can get two for twice the price?"

Finally, rear arms good call. Then brakes eh. Search HD-12. Yes, it never ends.
