We offer both kits and individual cables for your vehicle

 Gen 1 is for the 1989-1993 models with a single battery.

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. 

Battery Kits:

All Battery kits include covers and loom (free loom)
