How do I know f I have the towing Package?

Not sure you’ll get what you really want out of the AALs tbh. Might want to add some Sumo’s on top.

 

These AALs are for Tacoma, F150, GMC1500. My max payload is 1400lbs. F150 max payload is 1900-3000lbs. I was reading the reviews on Amazon and people with Tacoma's were satisfied with the results and people with bigger trucks saw not so much lift. I've only got 2 leaves going across the axle ....scares me. This extra spring with add another leaf at least. I can always add the Sumo's once I see how much room I have between the top of the spring and the stop were the bump stop hits. Some Sumo's have 5 layers and others have 4 ...I will see what fits best so it's not riding right on the Sumo all the time.

 

Uhh payload isn’t based on your leafs.. It’s based on your axle brother.

AAL won’t change a lot. Just letting you know.

 

Just pointing out the F150 is a much heavier truck. Plus if a truck has twice the payload capacity, one of the reasons being it has a more substantial axle, it probably also has stiffer springs. Again only one way to find out if it works for my situation.
"I am trying the add a leafs because I had such good luck with them (even though this is a different spring)on my last truck. I could fill the front half of the bed with fresh cut maple firewood and it wouldn't sag at all and that was with a loaded trailer. I could travel safely at highway speeds."
That was a 2001 Tacoma 4x4 with the 2.7ltr engine that bottomed out with any load added. I added the Wheeler 3 pack (same as the Icon 3 leaf) and after that I could load that sucker up with 2 rows of fresh cut sugar maple to the roof of the fiberglass cap. Right in front of the tailgate and it might go down an inch or two. In this case I was just shuttling firewood to the front of my property for splitting and stacking. It was a night and day difference.
I have a new 35hp tractor and can use the bucket for moving firewood around so I won't need to task the truck with doing that anymore. Basically just handling the weight of a fiberglass cap and towing maybe 2500lbs max.If I was trying to tow a travel trailer or go nuts off roading I wouldn't even try this!
