The Teck grounding kits use the highest quality wire and terminals available on the market. However, the biggest difference is that the Teck grounding kits are crimped with an industrial crimper and soldered for a bulletproof connection and corrosion resistance. Most other kits I've seen are just crimped with probably a basic plier which creates a connection that will likely fail over time.van48 said:i have seen some for 50 bux. any different?
