Like it says im doing the chevy rear spring swap on my 90 p/u and I was curious where you guys have been getting the shocks for them and also the part number. I found this
Will I need longer shocks?
Yes! You will definitely want longer shocks to take advantage of all that new travel you gained. Get Rancho 5012 or 9012's or Procomps. Bilstein 5100 series are also great shocks.

But they arent the part number I need can anyone help? I would like the Ranchos. I just want to make sure im ordering the correct ones since the springs will be different now. Any info is greatly appreciated

 

Every install is different. You need to measure the distance from the top and bottom shock mounts at full droop and full compression. That will tell you which lenth travel shocks you will need.

Don't forget to extend the bump stops with those new springs of yours.

 

ok well my question is why is every setup different? is it b/c people move the shock location also? I would just think that if everyone is installing the same springs then they would have the same shocks if they were mounted the same.... no?

 

Well, typically you'll find with the stock shock mounts, there is no way to fit a proper sized shock in there above 3" of lift and especially with springs with lots of down travel. I ran into that problem on my '85 before going to custom rear shock mounts:

- http://www.4crawler.com/4x4/4R_suspe...shtml#R-Shocks

So all depends on where you decided to mount the shocks; the upper and lower mount locations and the shock angles. Also depends on whether you move the rear spring hanger back or run a very long spring shackle and even whether you put the front spring hanger under the frame or french it into the frame and if you run blocks on the springs or not. So lots of options on mounting the springs and lots of options on the shocks = each setup is unique.
