Designing top quality Silverado engine parts for racing application or people who want professional levels of throttle response and acceleration, JMS makes a range of drive-by-wire throttle enhancement devices that can be used in your pickup. American Trucks carries a selection of their throttle enhancements, which use modern technology to ensure they’re easy to use while remaining powerfully effective. The components are made to be plug-and-play in most cases, so you can get them up and running in a short time. JMS’s 2007-2017 throttle enhancements for the Silverado get rid of both pedal lag and turbo lag, boost torque and horsepower in the low to middle ranges, and in some cases have optional remote control knobs so you can fine-tune throttle performance on the fly. Most are priced so you can make use of American Trucks’ free shipping on orders of $75+, too!
