Apologies to the OP for the hijack, but here's a pic of the ICON LCA (the coilovers on the table are Tundra):
Extended length ICON FJC coilovers have a shorter internal spacers to increase the shock travel so the full bump travel is the same but the droop will increase by ~1 inch at the wheel. That means with stock size tires (265/70R17), the wheel travel with aftermarket UCAs can be increase from less than 8" to between 10 and 11 inches (CV angle may become the limiting factor).
