Toytec is a great group of dudes, but [MENTION=118252]Chas of MRT[/MENTION] cannot (literally cannot) be beaten for prices on Icon... Make sure you contact him for future purchases to save some coin.
As for the "baby head" rocks... I go slow on stuff like that at 10-14psi typically. It's a bit rough, but in all the trucks I've been in, I've yet to find one that's making those things not be rough. I think you'd need some big ol' tires with monster sidewalls to smooth those things out.
I will be in the market for some Icon tubular upper control arms soon. I will make sure contact him when the time comes to buy.
