I hear ya....I have done this numerous times so am little more careful how I spend my money...mostly tho with racebikes, I built them up and sold them but always for less than what I put in but more than stock.....really I was moments away from going to get these kings, I mean literally on the road and it just hit me of all times I did before....and I know they are nice, and now am looking to trade out for 2500 (which originally I wanted just no deals at time)….so if this works out glad I didn't do it......but if 100% going to keep truck for awhile, I don't think you can do better than these.....ive ridden in king setups...granted they were a lil different but one thing I can say about kings is PLUSH....very controlled and super smooth....if you have coin and plan on keeping the vehicle w/o question I wouldn't hesitate....yeah its bit of inconvience to take em off after 50-100k but you will get essentially brand new set back for fraction of cost, and can tweak it if you prefer it a bit different......throwaways are in a different category....if your not that sensitive or care save your money, but if your very articulate and want the best and can notice subtleties its totally worth it.....like saying goes
the best you know is the best you've ridden.....and its so true
