I just put a 6 in procomp lift with MX6 shocks on my 04 silverado 2500. my question is has anyone used these shocks and what is your opinion. The reason is that I have the shocks turned as firm as they will go and they are still way to soft. On other vehicles I have heard that they are too stiff. Just wanted to see before calling procomp and seeing if the stamped numbers on the shock go with the correct part number. Wanted to see if people liked the shocks or if they prefered another brand.
