6.7 Cummins 2/0GA Battery Cable Kit – Big7Kits (DCMN10-67-00G)

Upgrade your 2010–2018 Ram 2500/3500 6.7L Cummins with a complete Big 7 battery cable kit built to deliver stronger current flow, faster starts, and long-term reliability that factory cables simply can’t match.

Factory battery cables degrade over time from heat, corrosion, vibration, and age. The result is voltage drop, sluggish cold starts, weak charging, and frustrating electrical issues. This 2/0GA Big7Kits system replaces the entire critical power and ground path with heavy-duty pure copper cables engineered specifically for the demands of the 6.7 Cummins.

Premium Construction

• Fine-strand, SAE-approved 100% pure copper cable (no copper-clad aluminum)
• Electromechanically crimped solid copper terminals rated for 700 lbs of pull force
• Marine-grade adhesive-lined heat shrink meeting MIL-I-23053/4 standards for superior corrosion and environmental protection
• Flexible J1127 jacket and labeled ends for straightforward installation
• Military-style corrosion-resistant battery terminals

Kit Includes

• Battery Negative to Fender Grounds (4GA)
• Battery Negative to Engine Block Grounds (2/0GA)
• Battery Negative to Frame Grounds (4GA)
• Alternator Charge Lead (2GA)
• Battery Positive to Starter (2/0GA)
• Battery Positive Crossover Cable (2/0GA)
• Battery Positive to PDC / Fuse & Relay Box (4GA)
• Fuse block with additional fuses
• 2 sets of military-style battery terminals

These cables improve electrical performance without requiring an alternator upgrade. Whether your truck is stock or modified, the heavier 2/0GA sizing provides extra capacity for cold weather, accessories, and future electrical demands while restoring crisp starts and solid charging.

Fitment: 2010–2018 Ram 2500 / 3500 with 6.7L Cummins
