Vengeance Racing offers many upgrade options for your 5.3L or 6.2L equipped GM Truck/SUV to bring out more performance while keeping the engine naturally aspirated. Our N/A packages focus on helping the engine breathe which creates more horsepower/torque while retaining a high level of reliability and great street manners. These combinations are perfect for the high performance street truck, or for drivers looking to push their vehicles on the drag strip. We offer a basic bolt-on package with our Stage I, as well as incorporate a performance camshaft and AFM delete system in Stage II. All of our packages are also configurable and customizable to meet anyone’s performance needs, including but not limited to E85 fuel conversions, Vengeance Racing valve covers/coil relocation, etc. Contact us today and see how our team can bring out the most performance from your Silverado, Sierra, Tahoe, Escalade, or Yukon!
