Of course, Illinois has the trifecta of lift laws for lifted trucks.

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 and bumpers.

A lot of the ultimate rides in Illinois have passed through the CPW Truck Stuff shop for a lift kit or other modification.
