I have a 2005 Gmc Crew Cab Sierra 1500, and I installed SpringTech 2" Coil spacers. The problem is I installed them on the top of the Coil Spring just like you would with Ready lift and Daystar spacers. Then i was reading on a website that the SpringTech spacers go on the bottom of the coil spring to the lower control arm. Can anyone give me any info, i called spring tech and they told me they go on the bottom. But has anyone else installed them on the top, and is it worth re-doing the install and getting another alignment. Any help would be greatly appreciated.
