Thanks, good thread.

On my '73 I just replaced KYB Gas-A-Just shocks with some new Bilstein HDs.

I was shocked at the ride quality difference. The Bilstein HDs are impressive. I was afraid the HDs wouldn't handle as well and I would regret not buying the Sport version but I can't really tell much difference in handling. My back can sure tell the difference. A couple of weeks later I replaced the 7 leaf spring with a new VBP composite spring and that make a difference as well. I think the HDs made more of a difference.

I have had the KYB's, Delcos, Koni Oils, Bilstein HD's and Sports over the last 28 years, looking for the right shock for my ride! I have spent too much money on shocks over the years but finally have the right combo of Bilstein HD's in front and Bilstein sports in the rear with the 360 composite spring. I had the KYB's with the steel and composite spring, Delcos with the the steel only, Koni's with the steel, and Bilsteins with the composite only!

I just replaced the 4 shocks on my 68. Used AC/Delco. They were reasonable and improved the ride substantially.

Just to clarify, shocks are for damping and controlling the speed of weight transfers. Their affect on handling is due to however long they delay transitions into and out of each phase of cornering, which is why adjustables are so exceedingly valuable in racing. That said, generally the more spring the more shock necessary, but they can't make up for a bad spring/bar setup.

They may be good on a vette but they suck on a Z71 GMC. They got me sea sick with all the floating and 3 leaked with in 3 years of mild use.

Big fan of Bilstein HD. Used them on more than one vehicle with excellent results. My '80 really handles significantly better and rides great, considering the poly bushings and gymkhana package. It's a lot more fun to drive on the curvy mountain roads now.

Rodney, which shock is best for you depends on your suspension setup and what you are looking for. Please remember that my experience with all of the shocks I mentioned above was based on thea rear spring I had at the time (see my answers above)Answers are as follows:

1. The best all around shock for ride and suspension control is the bilstein HD, not the sports, on my car.

2. Bilstein HD for the best ride giving up some control, the KYB Gas A Just with a steel rear spring also rides real nice. I found the GR-2's on on my other car (grand prix) way too soft so did not even consider for the vette. GR-2's are a standard passenger car shock designed for a comfortable ride and are NOT a performance shock by any standard-Like most things in life you get what you pay for-A GR-2 shock for a C3 is $25-you will get a $25 dollar shock, nothing less nothing more!! I have 6 Bilstein HD's on my 1994 Mustang Gt Convertible and they simply transformed the ride and handling characteristic of the car versus the OEM ford shock/Struts!

3. The Bilstein sports (30% stiffer than the HD's) give the best handling with a slight degradation in ride (I have a 360 monospring with these shocks though and the stiffer the spring the more rebound control needed. I found too much bounce with the Bilstein HD's versus the sports with the composite rear spring.

4. Bilsteins are a gas shock.

5. Sports for the best suspension control, HD's for the best ride-again my experience is with a 360 monospring.

6. Don't know the answer but the Sports are 30% stiffer than the HD's and I could feel the difference with the 360 monospring, thus the change and the one's in the rear of the car presently.

hope that helps!

I just had my rear suspension rebuilt. was talking to the guy who owned the shop, and told him I was thinking about putting on new shocks later this year. I asked him if thought Bilsteins were worth the extra money, and he said "No, go with KYB's.".

So, that is my plan, I'm putting on new KYB's later this year.

These are the shocks I plan on using, they offer a combination of quality, price, and performance.

I am just about to replace my shocks on my 77, can any of the above mentioned shocks still be used if I decide to lower my car at a later date?

Depends on how low you go. If you don't go any lower than Chevy Power book recommendations (highly suggest getting as near those as practical for handling) you should be fine with most shocks AFAIK. If you are lowering for performance I wouldn't throw just any old shock at it tho. Shocks that don't live up to expectations or your chassis' potential don't provide any value IMCO.
