Restore dependable electrical performance in your Chevrolet or GMC 6.6L LMM Duramax with the Big 7 Battery Cable Kit. Designed as a complete replacement for aging or corroded factory wiring, this vehicle-specific system helps reduce voltage drop, improve cold starts, and provide more consistent current to the starter, alternator, batteries, and electrical accessories.
Each kit is constructed from 100% fine-strand, SAE-rated pure copper cable with a flexible J1127 jacket for excellent conductivity and long-term durability. Solid-copper terminals are secured with gas-tight electromechanical crimps rated for up to 700 pounds of pull force, then sealed with marine-grade heat shrink to help protect the connections against moisture, corrosion, and harsh underhood conditions.
This all-in-one Big 7 system includes vehicle-specific replacement cables, corrosion-resistant military-style battery terminals, a MEGA fuse and fuse holder, and protective heat shielding or wrapping where required. Every cable end is clearly labeled to simplify installation and help ensure each connection is routed correctly.
• Cable Size: Choose 1/0-gauge or heavier 2/0-gauge pure copper cables
• Cable Finish: Available with Black / Ped, or Spyder-pattern protective sleeving
• High-Output Alternator Option: Adds larger cables for trucks equipped with a high-output alternator
