Without Stillen grounding kits you're losing horsepower and torque. Today's engine management systems utilize hundreds of sensors and in some cases over 12 onboard computers that constantly monitor all parameters of the engine and powertrain. Installing a Stillen grounding kit ensures all wire diameters are optimal for amperage and current travel distance, and that sensors and computers are not affected by power surges that can drain performance. They will also improve the shifting on automatic transmission vehicles, and in most cases noticeably improve shift times and reduce lag. Each kit features 8-gauge copper wire, gold plated connectors, 4- and 8-gauge ring connectors, and are developed specifically for your application. Select the Stillen kit designed for your vehicle.
