Review on Upgrade Your Ford F250 F350 Super Duty With Compatible Body Cab Mount Hardware, Ideal Replacement For KF04060BK Body Bushing Mount Kit, Suitable For 4WD/2WD Models (2008-2016). by Robert Byrd

Do not purchase these for new body mount bushings. Go purchase the bolts from Ford. These bolts do not have enough threads. So you have to use multiple washers before they will tighten up. They are also only grade 8.8 which is similar to a grade 5 bolt. Original equipment is a grade 10.9 which is similar to a grade 8 bolt. Some charts that I looked at have grade 8.8 bolts listed below the recommended 76 foot pounds of torque required for these bolts to tighten the body mounts.
