I'm on a Boat! AirBag w/ Lift Coils?

[Simpleman74]

Getting ready to purchase a new boat and wanted to see if anyone here is running airbags with lift coils or if I even need them. I have SAW 1.5" coils currently and plan on buying a SeaRay 21SPX that has a dry weight of 3400lbs. So with trailer fuel gear etc I would imagine I am flirting with 5k lbs:shrug:

I would hook up to the boat to give you an idea of how much it will drop the 4runner first. If you do end up needing bags, you may have to find a taller bag that will work properly with the SAW coils. Don't quote me on it but I think the Tahoe/Yukon bags are the same diameter but taller and work with lift coils. The other option would be to swap the SAW coils for coils with a high spring rate.

You can just find a catalog from firestone or other manufacturer. They list all the sizes including diameter and length. Find the one that's the right diameter, but longer by about the same length as your lift. Should be pretty straight forward.

Or go full air springs and get rid of the coils all together.
