        A SuperFlex rear coils are good for daily driver.For overlanding with additional constant load such as rear heavy bumper + rear winch + tire carrier + lots of stuff HD coils can be recommended.But HD rear coils give less comfort if driving empty

        A For such additional weight we'd better offer rear HD coils and front 700 lbs coils

        Yes, KDSS and everything functions well.
        Only X-REAS need to be disabled to use this kit if you have X-REAS shocks on your truck

        A Yes it will work with KDSS without any issues as long as the lift kit is installed properly by a professional shop. The ETA on the front and rear shocks will be about 2 weeks

        A UCA's are recommended but not require, the benefit of the UCA's is to  fix the caster when the vehicle is getting aligned and also helps you a  lot with articulation on the front end.
