Dodge RAM Gen 3, 2500/3500 Cummins Diesel I6 5.9L, 2003-2007, 2/0 Kit

Dodge RAM Gen 3, 2500/3500 Cummins Diesel I6 5.9L, 2003-2007, 2/0 (Kit) #790

Upgrade your 3rd Gen Cummins with this complete heavy-duty 2/0 battery cable kit, built specifically for 2003–2007 Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins diesel.

Factory cables on these trucks are a common failure point—corrosion, voltage drop, and hard starting are frequent issues. This kit replaces the entire battery cable system with larger 2/0 gauge pure copper cable for maximum conductivity, stronger cranking power, and long-term reliability.

Kit Includes

• Positive 2/0 battery-to-battery crossover cable
• Positive 2/0 battery-to-starter cable with starter-to-junction block wire and splice
• Left (driver-side) negative cable with 3 wires
• Right (passenger-side) negative cable with 2 wires
• 2 Positive + 2 Negative military-style battery terminals
• 4 lock nuts
• 2 red + 2 black military-style terminal covers
• 2 sets of terminal protector washers
• Protective loom
• 5 mountable + 5 standard zip ties

Fitment: 2003, 2004, 2005, 2006, 2007 Ram 2500/3500 with 5.9L Cummins I6.

Note: Most applications use a straight starter lug. Some late 2007 models may require a 90° starter lug—verify your starter connection before ordering if you have a late 2007 truck.

Hand-built in the USA with heavy-duty crimps and adhesive-lined heat shrink for superior corrosion resistance. A high-quality replacement that restores (and often improves) starting and charging performance.
