5.9|6.7 Cummins 2/0GA Battery Cable Kit – Big7Kits DCMN06-I6-00G

Upgrade the electrical system on your 2006–2009 Dodge/Ram 2500 or 3500 with the Big7Kits 2/0GA Battery Cable Kit. Built specifically for 5.9L and 6.7L Cummins-powered trucks, this complete “Big 7” replacement kit replaces aging, corroded factory cables with heavy-duty pure copper wiring for stronger starts, improved charging, and greater overall reliability.

Factory battery cables degrade over time from heat, vibration, moisture, and corrosion. This kit restores full current flow to the starter and charging system while providing extra capacity for accessories, cold-weather operation, or future modifications.

• Marine-grade heat shrink (MIL-I-23053/4) for superior corrosion and moisture protection
• Military-style corrosion-resistant battery terminals
• Clearly labeled ends for straightforward installation
• 2/0GA primary cables for higher current capacity and future-proofing

Fitment

Fits 2006–2009 Dodge/Ram 2500 and 3500 trucks equipped with the 5.9L or 6.7L Cummins diesel.
