I've been tossing around ideas in my head for upgrading my suspension and wonder if aftermarket UCA's are needed? At first, I wanted King coilovers up front and King reservoir shocks out back with some new UCA's (total chaos, Icon, etc), but the backspacing on my current wheel set up is over 5.5" (i've got 18x9.5 +25mm offset Vtech raptors), and everything I've seen for UCA's only allows for up to 5" of backspacing. Now, I'm just thinking of going ICON reservoir coil overs up front and reservoir shocks out back with no new UCA's. Right now, I'm just running a 3/1 redylift spacer kit and want the same height (but increased ride quality) from the aftermarket shocks. Do I need aftermarket UCA's or can I live with stock? I only want the upgraded suspension for better ride quality and a bit more wheel travel. I mainly use my truck as a daily river, but want the ability to take it off road a bit, no rock crawling or anything like that, she's my baby and I don't wanna bang her up....yet what does everybody think?
