River City Diesel
River City Diesel, LLC, consists of individuals who know aftermarket performance. Have confidence in us before and after the sale. We are not like so many other sellers that just drop ship from the manufacturer. We install and test what we sell. If we don't recommend it, its because it's something we wouldn't put in our own vehicles. Whether you're looking for an additional 2-4 miles per gallon or moderate to extreme added horsepower and torque for towing or sport/race application, we can get you the best system available for your needs and in your price range. We have done and continue to do extensive dyno testing on all key performance parts as well as real-world fuel economy testing and comparison. So if we say that we can get you 3 more miles per gallon, its because we've done it ourselves in your specific model vehicle.
