5.9|6.7 Cummins 2/0GA Battery Cable Kit – Big7Kits (RAMG3-0205-20G-59-67DIESEL)
Upgrade the electrical system on your 2002–2005 Dodge Ram 2500/3500 Cummins with this complete Big 7 battery cable kit from Big7Kits. Factory cables degrade over time from heat, corrosion, vibration, and age, leading to slow cranking, voltage drop, hard starts (especially in cold weather), and charging issues. This 2/0 gauge pure copper kit replaces the critical power and ground circuits with higher-capacity, longer-lasting cables for stronger starts, better charging performance, and improved overall reliability.
Unlike basic “Big 3” upgrades, this is a full Big 7 system that addresses more circuits for a more complete electrical refresh. It also helps prevent the charging system from overheating the passenger-side battery.
Kit Includes
- Battery Negative to Fender Grounds (4GA)
- Battery Negative to Engine Block Grounds (2/0)
- Battery Negative Frame Grounds (4GA)
- 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
Key Features & Construction
- Fine-strand SAE-rated 100% pure copper cable (not copper-clad aluminum)
- Electromechanically crimped solid copper terminals
- Marine-grade heat shrink sealing (MIL-I-23053/4) for corrosion resistance
- Clearly labeled ends for straightforward installation
- ANL fuse protection included
Fitment
2002–2005 Dodge/Ram 2500 & 3500 with 5.9L or 6.7L Cummins diesel engines.
Why 2/0 Gauge? 1/0 is adequate for many stock trucks. Choose this 2/0 kit if you want maximum current capacity for cold climates, winches, extra lighting, other high-draw accessories, or simply to future-proof the electrical system. No alternator upgrade is required to benefit from these cables.
This kit delivers faster starts, more consistent charging, and a more robust electrical foundation that will outlast typical factory wiring. Ideal for daily drivers, work trucks, and modified Cummins builds.
