Hey guys I have a reg cab and am going to be pulling this spring and summer and just have 4 leafs on the leaf springs right now. I am looking for how many leafs to add and put top leafs on or bottom or even mess with putting more on, I am just looking for the best setup for a reg cab. I will be using blocks when possible but for all other pulls I am going to need something more than what is on there. Any help would be helpful. Thanks
