1. Factory shocks can be used with this suspension lift kit, however new replacement shocks are strongly recommended. See options above.
2. Torsion bar keys are designed to install with a stock suspension only. Do not use with other types of lift kits. Will void warranty.
3. Note: All GMC/GMC factory torsion bar keys are marked with a color code in paint on the key. If your vehicles markings are purple, please make sure to select that in the option field above.
Hi does this kit add 1 inch off lift to what is existing. Not sure if this is normal but my truck has a block that looks stock and measures around 1 inch high now.
This kit lift the front 2" and the rear 1". If your vehicle already has a 1" block in the rear this is not factory, it is aftermarket and you will not need the rear block when doing this kit. You can go with just the front kit, part number 12904
