You could sleeve it, that has worked well for me in the past on other trucks. Or if you go the custom route, make it adjustable so you could get your rear axle back to where it was before the lift. It shouldn't make much of a difference if it's under a 2" lift, but as you go higher, your rear tires will be moving ever so slightly closer to the front of the truck..
Did you record any of the SCIENCE in your lift???
