GMC Lowering Keys
Torsion bar keys are a great way to drop the front suspension of your GMC truck. Provided you have the right tools, installation of your keyways on your front torsion bars will be a snap.
Aftermarket GMC keys are casted to provide up to a 3 inch drop by relocating the hex torsion bar opening a few degrees. Lowering torsion keys can be used in combination with air ride suspension as well. Factory GMC fit keyways are sold in pairs only.
