Replace the cab-mount bolts on a Super Duty when the factory hardware is rusty, stripped, or the wrong length for a new Daystar bushing. A short or seized bolt will not clamp the cab back down on the frame. Daystar KF04057ST is the bolt kit for KF04050BK and KF04050KV body mounts, not a bushing kit by itself. Several lengths are in the box because one bolt does not fit every cab.

• Part number: Daystar KF04057ST is high-strength M12 hardware for 1999-2018 Ford F-250 and F-350 Super Duty trucks, regular cab, Super Cab, and crew cab.
• Use it with: Daystar body-mount kits KF04050BK or KF04050KV only. Those kits do not include bolts.
• In the kit: Two M12 x 1.75 x 130 mm bolts, six M12 x 1.75 x 110 mm bolts, six M12 x 1.75 x 150 mm bolts, two M12 x 1.75 x 200 mm bolts, and eight M12 washers.
• 2007-2016 lengths: Use six 130 mm bolts, two 110 mm bolts, and eight washers on a regular cab, crew cab, or Super Cab.
• 2017-2018 lengths: Use six 150 mm bolts, two 200 mm bolts, and eight washers on a regular cab, crew cab, or Super Cab.
• Earlier trucks: On a 1999-2006 truck, use the bolt that matches the hole. If the thread or length does not match, reuse the factory bolt.
• After install: Torque the bolts to the factory spec, then retorque them after 500 miles.
• Does not fit: Any job that still needs the polyurethane mounts. It is also not the add-on hardware for KF04058BK or KF04060BK, which already include bolts.
• Not in the box: Polyurethane mounts and steel shells. Those come in KF04050BK or KF04050KV.
