Default Question on Bilstien Shocks...

Hey guys. I was clicking around on ws6store and saw the Bilstien HD shock package...and then below that for $20 more is the SLP specification Bilstien shock package...whats the difference between the two? anyone far superior to the other? I got the factory decarboned shocks on mine and id like to put the bilstiens on there...im looking for a "factory" shock so thats why im looking at bilstiens. Sorry for my book and if someone would clear this up for me id appreciate it. thanks.

The SLP Bilstiens have a bit more rebound damping and a smidge less compression damping compared to the HDs. Should work well with slightly stiffer aftermarket springs like the Eibach ProKit springs. The HDs are valved to work with the stock springs. I would pick the SLP version if I had to pick between the two even with the stock springs.

Good shocks for stock springs. Nice upgrade. Why do you want to upgrade?

I'd vote HD's. Cheaper to start with (I sell them for $329). And the loss or compression damping without more spring rate to help make up for it is not smart IMHO.

This assumes you have stock springs, and are looking for a good all around competent car. Neither is a what I'd consider the best handling. The HD's are simple a better match for the stock springs IMHO. *IF* the SLP's didn't have less compression, I would use those before HD's because I prefer a bit more rebound control. However, the loss of compression rate (which controls unsprung weight) trumps the desire for a touch more rebound damping when stock spring are involved.

i really dont want them to do a lot of handling stuff with, though that will be a nice bi-product. i would just like to do a lot of the SLP optioned stuff that was available. the car is mint and just kinda want to "dress it up" more than make it race. thanks a lot for the quick responses, i really appreciate it. if anyone has anymore input i will be checking on this for awhile. so feel free to post up, im not ordering today or anything. I just saw that there was a difference, and i didnt know there was one. So thank you all.

Do you run Eagle F1's on the car still? Will you always? They are more visable (obvious they are not stock) than shocks are. And FWIW, the HD's look exactly the same as the SLP's but for the part number.

Far smarter to run the shock with the more appropriate valving. Unless of course you don't give a lick about the car actually being a piece of machinery that has a job to do, and think of it more as art.

HD's are valved for stock Z28 springs, which most later SS's like yours have if the car has the orange DeCarbon shocks.

The SLP shocks are valved to match up with the SLP Eibach springs which were part of the level 1 package. If the car came with those springs OE, it'd also have the SLP shocks already installed.

I say HD's, all the way. Better match for your spring rates, cheaper too. And look just the same as the SLP's. Nobody would ever know anyway. Besides only Level 1 cars had those shocks, and you don't have the spring to match.... though you could buy those as well.

I recently purchased both items SLP springs and the Bilsteins new from members on forums. The question I have is I have heard these will drop my Z28 with the factory decarbon shocks and springs 30mm, is it true? Does anyone have a picture of before and after, I went through the sticky of lowered pics and couldn't find this combo, so hopefully someone has a picture.
