shock rebound/compression question
So i have some questions about shocks. I was looking at some Bilstein shocks for my 77 c10. They have compression/rebound numbers, like 7/3, 6/4.. what do they mean, (which is more, which is less) and how do i determine where i should start at? I have a 77 C10 with full frame, bagged, body dropped. I dont have front shocks right now,(custom chest plate and arms), and my rear shocks are mounted on the rear link bars. I have a sbc with a 6-71 blower turning 608hp at the wheels. I have an impala rear end with 3.08 gears right now. This is a cruiser/ freeway play vehicle. doesnt really see track time as the front suspension isnt really setup for carving. but i am running Slam SS8's in the front, and SS7's in the rear on the bar.
Thanks for any help!! |

Re: shock rebound/compression question
Here is a good article on how shocks work. http://teinusa-blog.com/compression-and-rebound/ The numbers you are looking at are the ratio between the compression and rebound. A bigger number means it is stiffer in that direction. As what shock to run on your application I would start with something with a 60 40 split and stiffer on compression. Just as a guess but it will take some trial and error. Could always try some adjustable shocks to tune the ride.

Re: shock rebound/compression question
When you start looking at the cost, it's hard not to go with at least a single adjustable shock. Usually you have fixed, single adjustable, and double adjustable.
I put QA1 single adjustables on the front of my ls-swapped 66. It did a better job of controlling the weight, and I can loosen them up to run at the track if I want to. Something like that will run in the $85-150each range, but its infinitely better than even the "higher end" non adjustables in the 35-60$ range.
