This upgraded battery cable kit replaces old/worn out battery cables in your LB7, LLY or LBZ Duramax powered truck (2001-2007) for more power, better performance, and faster starts from your vehicle. Let's just say that when the factory made your original cables, they didn't make them to last.... and ours will likely outlast your truck!

Why do I need your cables?

You know how when it gets colder, it takes longer to get going? The issue is that the cables your truck came with, aren't the cables they started out as. They've got corrosion keeping the full amount of current from reaching the starter... or the previous guy/gal who owned your truck was a hack, leaving you to deal with their sub-par work. All of these things can contribute to issues with your electrical system.

What makes these cables so special?

We're nerds for specs and finer details around here. None of that CCA (copper-clad aluminum) that's used in inferior products, or stereo installations. We only use SAE J1127 fine-stranded oxygen-free copper (OFC) cable. Then using a powerful electromechanical crimping machine, we crimp each tin-plated copper lug, and finally finish the construction by adding an environmental seal made of marine-grade dual-wall adhesive-lined heat shrink. Also included are military style corrosion resistant battery connections and a MEGA fuse and holder. To make the entire install simpler, every end will be labeled for ease of installation.

Do I need a bigger alternator to run these cables?

No. Every vehicle can benefit from our "better than factory" cables. The years, along with environmental damage from rain/salt water/corrosion, can greatly impact your electrical system. Our customers have consistently reported that their vehicle starts faster, charges the battery better, and many times cured electrical gremlins that were brought on by compromised wiring.

These aren't just any old "big 3" cables, these are the "Big 7" from JeepCables!

JeepCables by Big7Kits. Built in Vancouver, WA, USA with US-made wire.
