Thumbnail Filmstrip of 5.9|6.7 Cummins 1/0GA Battery Cable Kit Big7Kits Images
(NOTE: Some 06-09 will have a 90* connection at the starter, some will have a straight connection. Be sure to let us know in the order notes which your truck has.)
We partnered with the top diesel shop in town—and their expert mechanic—to bring you a premium upgraded battery cable kit for Dodge Cummins-powered 2500/3500 trucks. This kit replaces old or worn-out factory cables, delivering more power, faster starts, and improved overall performance. Factory cables weren’t built to last, but ours are engineered to outperform and outlast your truck, giving you reliable performance in every condition.
Why our battery cables are a must-have:
- Eliminate slow starts: Cold weather or old, corroded cables can prevent full current from reaching your starter, causing slow or unreliable starts.
- Restore electrical performance: Previous owners or environmental damage like rain, salt, and corrosion can compromise your system. Our kit resolves these issues and improves charging efficiency.
- High-quality materials: Made from fine-strand, SAE-approved pure copper, never copper-clad aluminum (CCA) used in inferior products.
- Professional-grade assembly: Each solid copper end is crimped with a precision electromechanical machine and sealed with marine-grade heatshrink (MIL-I-23053/4) for maximum protection.
- Complete, corrosion-resistant kit: Includes military-style battery connections, ANL fuse and holder, and clearly labeled ends for easier installation.
- Better than factory—no alternator upgrade required: Our cables improve battery charging, often fix electrical gremlins caused by old wiring, and enhance reliability.
Big 7 Battery Cable Kit improvement: Stops the charging system from overheating the passenger-side battery.
Choosing the right gauge: If your truck remains stock, 1/0 GA is sufficient. For future modifications like winches, extra lighting, extreme winter conditions, or if you want to future-proof your vehicle, 2/0 GA is the smarter choice. Either way, you’ll enjoy faster starts, more reliable charging, and a stronger, longer-lasting electrical system designed to keep your truck running at its best for years to come
Kit Includes:
- 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)
- Alternator Lead (2GA)
- Battery Positive to Starter (1/0 or 2/0 depending on kit)
- Battery Positive Crossover Cable (1/0 or 2/0 depending on kit)
- Battery Positive to PDC (Fuse and Relay box) (4GA)
- Fuse block with additional fuses
- 2 sets of military-style battery terminals
