This is a kit that will include everything you need to do the coilover swap on GM 1999-2006 torsion bar 1500 trucks and SUVs and will include the following:
This kit will work on all 1500 Silverados, Sierras, and year 2000 and up model SUVS including Tahoes, Suburbans, Yukons, Denalis, Escalades, etc. This does not fit any other truck models or years, including 2500/3500s, Fords, Rams, or anything other than 1500 GM trucks with torsion bars. 1999 SUVs were still the older body style, and this kit will not work for those either.
