I would have to dig for the receipt for the exact amount. Lets see, for extended travel IVD coated Icons, Camburg BJ UCAs, ball joint covers, 1.5" rear SAW coils, rear Bilstein 5100s, and spanner wrench I believe it was right around $1800 from Wheelers offroad with the Black Friday discounts. It completely changed how my 5th gen feels all for the better. I feels light and nimble just like a 4runner should feel. The Icons took away a little of the nose dive but, along with the SAW coils and 5100s, really improved the cornering abilities- a lot less body roll.
The only thing I wouldn't do over is the Camburg UCAs. There is not much (if any) additional caster built into them like they claim. I'd go with Icon or TC instead. Oh well, live and learn.
