Thumbnail Filmstrip of 5.9|6.7 Cummins 2/0GA Battery Cable Kit Big7Kits Images
NOTE:Some 06-09 will have a 90* connection at the starter, some will have a straight connection
We partnered with the best diesel shop in town—and their most trusted mechanic—to bring you a premium upgraded battery cable kit built specifically for Dodge Cummins-powered 2500 and 3500 trucks. This kit replaces your old, worn-out factory cables to deliver stronger performance, faster starts, and improved electrical efficiency. The truth is, the factory cables were never designed to last—but ours are built to go the distance and likely outlast your truck.
Why upgrade to our battery cables?
- Cold-weather reliability: When temperatures drop and your truck struggles to start, corroded factory cables are often the culprit. They can’t carry full current to your starter, making cold starts a headache.
- Fix past wiring issues: If your truck’s previous owner used cheap or poorly installed wiring, our kit eliminates those weak points and restores your electrical system to peak condition.
- Top-tier materials: We never use CCA (copper-clad aluminum) like inferior products. Every cable is made from fine-strand, SAE-approved, pure copper for maximum conductivity and durability.
- Built for lasting protection: Each solid copper end is electromechanically crimped for unmatched strength, then sealed with marine-grade heat shrink that meets MIL-I-23053/4 military standards to guard against corrosion and moisture.
- Ready-to-install design: Includes military-style corrosion-resistant battery terminals, an ANL fuse and holder, and clearly labeled ends for easy installation—no guesswork required.
- No alternator upgrade needed: Our cables outperform stock ones without requiring a bigger alternator. Customers report faster starts, stronger charging, and even the resolution of mysterious electrical issues caused by degraded wiring. Plus, our Big 7 Battery Cable Kit upgrade prevents your charging system from overheating the passenger-side battery.
Whether you’re maintaining a stock setup or preparing for future mods, this upgrade is an investment in power, reliability, and peace of mind. Choose 1/0 GA for standard configurations or 2/0 GA if you plan to add accessories like winches or lights, live in extreme cold, or want to future-proof your truck’s electrical system. With our cables, you’ll experience dependable performance—no matter where the road takes you.

- Battery Negative to Fender Grounds (4GA)
- Battery Negative to Engine Block Grounds (1/0 or 2/0 depending on kit)
- Battery Negative Frame Grounds (4GA)
