Upgrade the electrical system on your 2006-2009 Dodge Ram 2500/3500 5.9L or 6.7L Cummins with this premium Big7Kits “Big 7” battery cable kit.

Developed in partnership with a top diesel shop and their lead mechanic, this kit replaces aging, corroded, or undersized factory cables with a complete high-conductivity system that delivers faster starts, stronger charging, and greater overall reliability—especially in cold weather.

Key Features & Benefits
