6.0 Powerstroke 2/0GA Battery Cable Kit – Straight Starter Lug | Big7Kits (FPSD03-60-00G-ST)

Upgrade your 2003-2007 Ford Super Duty 6.0L Powerstroke with a complete high-performance battery cable system built to deliver maximum current where the factory cables fall short.

Factory battery cables on the 6.0 Powerstroke degrade over time from heat, corrosion, vibration, and environmental exposure. The result is voltage drop, slow or hard starts (especially in cold weather), dimming lights, and intermittent electrical gremlins. This Big7Kits 2/0GA kit replaces the compromised factory wiring with a full “Big 7” pure-copper system engineered for superior conductivity, durability, and long-term reliability.

Key Features

• 100% fine-strand SAE-rated pure copper wire (no copper-clad aluminum)
• Flexible J1127 jacket for easy routing and long service life
• Gas-tight electromechanical crimps rated for high pull strength
• Marine-grade adhesive-lined heat shrink (MIL-I-23053/4) for superior corrosion and moisture protection
• Military-style corrosion-resistant battery terminals
• Clearly labeled cable ends for straightforward installation
• Straight starter lug (designed for Denso-style or other high-torque aftermarket starters)

Important: Some 6.0 trucks use a 90° starter connection while others (especially those with aftermarket high-torque starters) use a straight lug. Verify the connection style on your truck before ordering.

Kit Includes

• Battery Negative to Fender Grounds (4GA)
• Battery Negative to Engine Block Grounds (2/0)
• Battery Negative to Frame Grounds (4GA)
• Battery Positive to Solenoid (2GA)
• Battery Positive to Starter (2/0) – Straight Lug
• Battery Positive Crossover Cable (2/0)
• Starter to Starter Relay (10GA)
• 2 sets of military-style battery terminals

This is a true complete system — not a basic “Big 3” upgrade. Customers consistently report faster cranking, stronger charging, more stable voltage under load, and the elimination of long-standing electrical issues after installation.

Fits: 2003–2007 Ford F-250 / F-350 Super Duty with 6.0L Powerstroke

Built to outlast the truck and restore the electrical performance your 6.0 was designed to have.
