Blessed Performance has the Big7Kits Battery Cable Kit for 2001-2007 Chevrolet Duramax LB7 / LLY / LBZ 6.6L trucks.
This upgraded battery cable kit replaces old/worn out battery cables in your Chevrolet Duramax powered truck 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 these will likely outlast your truck!
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. 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 Big7Kits!
