The other issue is, what are the dimensions of a Bronco (early or late?) shackle in addtion to the eyes at the end of the leaf. Even if the eyelets are okay would it fit or not?
You asked about the construction of Warriors and how strong are they. This has been discussed before. You can click on "Gerald's Truck" in my sig line below and page down to my second post which is an article on some of the mods I've done. There is an extensive section about the Warriors since it was I who designed them and got a company to build and market them. They are made of 3/8" plate steel, crossbraced, and literally bulletproof. You will bend your frame before bending a Warrior.
If you decide to be the Revolver guinea pig please keep us updated because there are many who are wondering about it. You will have to modify that leaf eyelet though before trying it, so there's money out your pocket before you even get to buying the Revolvers, which ain't cheap by anyone's definition. Then you get to test them on a vehicle that the manufacturer itself (Revolver) says it will fail on.
And Clint has a point. For paying the big money to get a little added droop, there have been tales of wheel hop side effects that lessened, not gained, traction in many situations. It's a complicated issue and won't be answered for Explorers until someone actually tries it and uses (abuses) it on trails in one of our vehicles to see what it really does and if it is worth it.
