Description
Support the added current demands of a high-output alternator with the Big 7 High Output Alternator Cable Upgrade. Intended for alternators producing more than approximately 180 amps, this upgrade replaces the standard 2-gauge charging cable with a larger 1/0-gauge cable to help reduce voltage drop and deliver power more efficiently. Constructed from fine-strand, SAE-rated pure copper wire with a flexible J1127 jacket, the cable features gas-tight crimped terminals and marine-grade heat shrink for dependable conductivity and corrosion resistance. When ordering separately from a complete kit, provide the vehicle application to ensure the correct fitment.
