The IFS suspension was removed and that was the majority of the strength in the rails. They need to now be reinforced to handle the extra load that the IFS once did. Anytime you do an IFS to solid axle you need to do that or you risk bending or even braking the frame. Especially if you use leaf springs. Good cheap insurance.
