Well, the problem with leaving overloads in is they kinda end up acting like a big fork on a fork lift sticking out like that. Problem with taking them out is once you do you can get more stuff out of your suspension which is exactly what will kill that particular leaf spring. They were never meant to go beyond flat or much beyond at all. That is exactly what the overload is there to prevent. The third option as Stephen and I discussed it is to go to a spring shop and have a couple smaller leaves made to substitute for the overload. This would step the stresses on the spring down nice and gracefully.
Another thing that can be done is to bump stop the axle from having to much upward stuff. This is probably the direction I will end up going and maybe cutting off some of the length of the overload. At least for the short term. After all I can't get to carried away with tire stuffing anyway. Some others may find benefit in one of the other options or just run it and see what happens.
