DOITHARD, you did not say if you were going to upgrade your overload spring pack or springs. If you are happy with the rode of your truck without the TC, my suggestion is to leave the springs as they are, and modify the overloads only.
After modifying the main springs on three different trucks, I finally l accepted that the ride was so much rougher without the TC. I modified with what was called progressive springs. Each time, I went through the expense to change them back. I also finally realized it was the overloads I should have been modifying.
