Trying to understand the patch work of lift laws by state can be confusing. Of course, Illinois has the trifecta of laws for lifted trucks and Jeeps. There is a suspension lift limit, a maximum frame height limit and a bumper height limit. However, suspension lift kits are allowed in Illinois as well as aftermarket wheels and tires, performance shocks, aftermarket bumpers, and grille guards. A lot of the ultimate rides in Illinois have passed through the CPW Truck Stuff shop for a lift kit or other modification.
