You are losing horsepower and torque without STILLEN's new Grounding Kits. 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 STILLEN's Grounding Kit ensures that sensors and computers are not affected by power surges that can drain performance. This ensures that all wire diameters are optimal for amperage and current travel distance.

These kits feature 8-gauge copper wire, gold plated connectors along with 4-gauge & 8-gauge ring connectors, and are developed specifically for your application. Available in silver or red.

These grounding kits will also improve the shifting on automatic transmission vehicles, and in most cases noticeably improve shift times and reduce lag.



About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.

    I have always been a fan & advocate of grounding the engine well. However, I can be a bit of a, Sheldon Cooper, when it comes to cars. I noticed that my engine did run smoother after the installation. I also installed the engine dampener brace at the same time. Every little bit counts. Performance comes from tuning the entire machine, not just corralling Equine...
