$4400.00 is for the SRT-10 kit.... I spoke to Fred Polo at STS. He said our kits are temporarily on sale for the summer. KRC had luck tuning someones truck on here with the STS and SCT tuner. And as we all know these trucks arent gonna handle much over stock on a stock bottom end. Is it the "best" route? Probably not. Is it prolly a good option with a good tuner and a mild build. Prolly have good results then..... I just thot Id give you guys a heads up. If you have no interest then dont pay attention to it. If you are interested then here ya go. And if they sell then theres a chance our venders like Stinker and ViperJeff make some profits.......
