Hey, i have a set of my stock coils off my 2004 sierra for sale and a guy wants to buy them for his 2000 reg cab silvy, he wants to know if they are the same if and they will work. He actually wants to use one or something because he cut up his stock one. Anyway, are they the same lenght from 2000 to 2004? I know my truck versus my buddies '06, his is like an inch lower factory than mine was, i had to get 1" drop coils to get the same look as my buddy with the same tires and wheels. Anyway, hopefully i can get some response on this by tomorrow so he knows whether or not to buy them from me.
