Beefier Leaf Springs
Right now I've gotta make do with what I got. My F150 will be hauling really heavy loads i'm wondering if anyone knows of larger springs, i'm okay with horrible ride so long as it gets the job done. I will be installing the Moog Springs in the front though in hopes to clear tires.

Heavier springs will REDUCE the weight the truck can carry because it then has to also carry the extra weight of the springs. Just keeping the weight up does not make it better for the truck - it makes it worse because the CG is higher (and you've added the weight of the springs). If the truck can't carry what you need, make 2 loads, or use a trailer, or rent/borrow a bigger truck. Tearing up your F150 is not a solution.

It isn't the springs you have to worry about it is the wheel bearings, which in the 8.8 axle end up shouldering the load. In the F250 and F350 of the same generation, the rear axle shafts bear the load.
Basically you are endangering your life and the lives of everyone you are driving near. Consider making two trips.

That sounded backwards enough I had to look it up. And it is backwards.
The 8.8 is a semi float, meaning it bears load and torque stresses in the axle shafts, is held in by a clip, and runs on one smaller bearing. Being subjected to weight plus torque means exceeding that can snap an axle shaft or C clip and lose the wheel when going down the road.
In a D60/Sterling full float, you have a pair of larger bearings shouldering the entire weight of a load, axles are only stressed by torque, and in the event of an axle failure can't be ejected from the vehicle.
Still correct that bearings/halfshafts are the limiting factor, though OP never said what kind weight he plans on moving.
@TheUnknownGuy Check your door sticker, weigh your truck, do the math to figure out what you can carry.

Thanks SaltEater I hadn't had my cup of coffee yet when I wrote that post
