These cables are for Gen 3 Dodge Ram trucks (2003-2007 models) with 5.9L Cummins diesel.

We offer both kits and individual cables for your vehicle.

How we build them:

The cables are built from 2/0 (“two-aught”) cable for the starter and engine block grounds (with optional 3/0 cold weather/hard start upgrade) and the tin plated (for corrosion resistance) copper terminals.  To prevent corrosion from the battery’s acidic fumes, we crimp the terminals with a 12-ton hydraulic crimper then seal the connection with adhesive lined heat shrink.  Cables are shipped with anti-corrosion battery washers, military-style battery terminals with “Nylox” style lock nuts. 

IMPORTANT NOTE: Some late 2007 models require a 90-degree starter lug.  If you have a 2007 model, check the starter cable before ordering.  If you are buying the battery-to-starter cable separately from the kit and need the 90-degree style, purchase cable for the gen 3, 6.7L here.

In stock and ready to ship

The cables on this page are in stock and ready to ship.  Orders typically ship the next business day.  If you want them a day sooner, we offer a rush service.  See a description of rush service at the bottom of the page.
