5.9 12v Cummins 1/0GA Battery Cable Kit – Big7Kits
Upgrade the electrical backbone of your 2nd Gen Cummins with the Big7Kits 1/0GA Battery Cable Kit. Factory battery cables were never built for longevity—years of heat, vibration, road salt, and corrosion create voltage drop, slow cranking (especially in cold weather), weak charging, and electrical gremlins. This complete “Big 7” kit replaces the worn OEM wiring with a purpose-built, high-conductivity system that delivers faster starts, more reliable charging, and stronger overall electrical performance.
Why this kit stands out
- Pure copper construction — Fine-strand, SAE-approved pure copper cable (not copper-clad aluminum/CCA) for maximum conductivity and current flow.
- Professional terminations — Solid copper ends are machine-crimped for a gas-tight connection, then sealed with marine-grade adhesive-lined heat shrink meeting MIL-I-23053/4 for superior resistance to moisture, salt, and corrosion.
- Military-style battery terminals — Corrosion-resistant terminals included for long-term reliability.
- System protection — Includes ANL fuse and holder plus a fuse block with extra fuses.
- Easy install — Every cable end is clearly labeled.
- Exclusive Big 7 feature — Designed to help prevent the charging system from overheating (“boiling over”) the passenger-side battery.
No alternator upgrade is required. Restoring proper cable capacity benefits any truck—stock or modified—by reducing resistance and restoring full current delivery to the starter and charging system.
Kit Includes
- Battery Negative to Fender Grounds (4GA)
- Battery Negative to Engine Block Grounds
- Battery Negative to Frame Grounds (4GA)
- Battery Negative Aux Grounds (6GA, if needed)
- Alternator Lead (2GA)
- Battery Positive to Starter (1/0GA)
- Battery Positive Crossover Cable (1/0GA)
- Battery Positive to PDC / Fuse & Relay Box (4GA)
- Fuse block with additional fuses
- 2 sets of military-style battery terminals
Fits: 1994–1998 Dodge Ram 2500/3500 with 5.9L 12-valve Cummins
Gauge note: 1/0GA is ideal for stock or lightly modified trucks. Choose the 2/0GA version if you run high-draw accessories (winch, lights, etc.), live in extreme cold, or want maximum future-proofing.
This is a complete Big 7 upgrade—not a basic “Big 3” kit—engineered specifically for the 1994–1998 5.9 12-valve Cummins dual-battery layout.
