I have the Stage 1 Procomp 6". Spacers and blocks. After my tire/wheel swap i will be looking at A custom set of Alcan springs and to get something up front to knock out those spacers. Haven't decided 100% what i want up there yet.
I see lots of Tundra folks with procomp 6" lifts that are adding Icon and other aftermarket shock manufactures coil over set ups to enhance their rides and add lift. I hear nothing but good things!
