5.9 12v Cummins 2/0GA Battery Cable Kit – Big7Kits
Upgrade the electrical system on your 2nd Gen 12-valve Cummins with this complete Big 7 battery cable kit from Big7Kits. Factory cables degrade over time from heat, road salt, moisture, and corrosion, creating voltage drop, hard starts (especially in cold weather), weak charging, and random electrical issues. This kit replaces the worn OEM cables with a premium, properly sized pure-copper system designed for real diesel reliability.
Key Benefits
- Faster, more consistent starts
- Improved battery charging performance
- Reduced voltage drop under load
- Eliminates many “electrical gremlins” caused by high-resistance factory wiring
- Better current delivery for accessories and future modifications
- No alternator upgrade required — every truck benefits from lower-resistance cables
Construction & Quality
- Fine-strand, SAE-approved pure copper cable only (no copper-clad aluminum)
- Solid copper ends electromechanically crimped for maximum strength and conductivity
- Marine-grade heat shrink seals meeting MIL-I-23053/4 specification for protection against water, salt, and corrosion
- Military-style corrosion-resistant battery terminals
- ANL fuse and holder included for system protection
- Every cable end clearly labeled for straightforward installation
Gauge Guidance
2/0 GA is recommended for future-proofing, high-draw accessories (winches, lighting, inverters, etc.), extreme cold climates, or anyone who wants maximum performance margin. 1/0 GA is generally sufficient for mostly stock trucks.
Kit Includes
- Battery Negative to Fender Grounds (4GA)
- Battery Negative to Engine Block Grounds (2/0)
- Battery Negative to Frame Grounds (4GA)
- Battery Negative Aux Grounds (6GA, if needed)
- Alternator Lead (2GA)
- Battery Positive to Starter (2/0)
- Battery Positive Crossover Cable (2/0)
- 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 Diesel
This is a full Big 7 upgrade (not a basic “Big 3”), engineered with input from experienced diesel shops to address the real weak points in the 1994–1998 Cummins electrical system, including a design improvement that helps prevent the charging system from overheating the passenger-side battery.
Restore reliable power delivery and long-term electrical performance to your 12-valve.
