Why replace UCAs?

Pfffft... I've dialed in more caster on school busses and party wagons lol. If all else fails, just pull the front upper control arm mount in some. Reduce caster and still keep the tire out of the fire wall.

Right on but I maxed out the lower adjustment. A big ass pry bar got us where we needed to go but there's nothing left. My tires are as far out as they can be while going up 2+" in height. I'm not worried about it really. In 50,000 miles all of it comes off and on to the next Raptor!

I doubt you'll have a problem. I'd rather be over caster than under caster. You can leave the lowers alone. When you bring the UCA front mount in, it will bring the top of the knuckle forward, reducing positive caster. As a result you'll also add some negative camber but probably not enough to require more adjustment correcting it. You could do the same by adjusting the UCA rear out, but it would add camber while reducing caster. OR you could work both the UCA mounts and achieve less caster and keep camber pretty close to where it was before. Lots of possibilities with the ICON arms

Yeah, my head is spinning!! I think you guys have forgotten more than I know. Caster, Camber, Heel, Toe, Dosey Doe! It sounds like a country line dance.
