This is a great Jeep SRT8 if you are thinking about doing a serious build with heads/cam, nitrous or forced induction. The engine is low mileage and will easily handle these modification. The bigger piece is the inclusion of the SHR Gen 1 Viking transmission rated to handle 1,000 whp. If you know anything about modern Mopars, the weak link is the OEM transmission. Add a supercharger on the OEM transmission and you are likely to destroy it in very short order. With this transmission you can safely add the mods of your choice and know that you will not incur any costs later to upgrade your transmission.Thanks for the interest and this Jeep SRT8 is guaranteed to not disappoint.
