The ICON Vehicle Dynamics 5 Lift Leaf Spring Hardware Kit eases the installation of ICON leaf springs onto the 2017-2024 Ford F-250 & F-350 Super Duty. Because of the placement of the fuel tank, the driver side front leaf spring hanger bolt cannot be removed without dropping the fuel tank. This replacement bolt kit allows the OE bolt to be cut and removed while leaving the fuel tank in position, and then replaced with a new bolt with the new leaf spring, drastically shortening installation time. Featuring a genuine Ford bolt, you can rest assured that the new mounting bolt is up to the task of securing the new leaf spring in place.
