Jack: Thank you very much...i didn't realize that the all season radial thread was already posted, and I realized it after i already started a new thread. I also figured that i'd group it all together b/c i'm going to be replacing both at the same time. oh well...
Do you have any brand loyalty for shocks?
I checked the spec sheet for the 99 silverado z71's, and they list the z71 option as having a longer travel than the 4x4 models... Thanks a lot!
