 These cables are for Gen 2.5 Dodge Ram Trucks (1998-2002 models) with 24-valve Cummins Deisel.

We offer both kits and individual cables for your vehicle.

Note: that these cables are not an exact drop-in bolt-on replacement.  They require that you splice leads into the existing wiring (more info). Cables are shipped with connector and heat shrink to complete the splice.

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. 

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.
