7.3 Powerstroke 2/0GA Battery Cable Kit – Straight Starter Lug (Big7Kits FPSD99-73-00G-ST)

Fits: 1999–2003 Ford Super Duty F-250 / F-350 7.3L Powerstroke

If your 7.3 Powerstroke is slow to crank, struggles in cold weather, or shows inconsistent electrical performance, the problem is often the factory battery cables—not the batteries. Over time, original cables corrode, develop high resistance, and restrict current flow to the starter and charging system.

This Big7Kits 2/0GA complete cable kit replaces the worn factory wiring with a true “Big 7” upgrade. It delivers stronger starting power, better charging, and long-term reliability that is built to outlast the truck.

Key Features

• 100% fine-strand, SAE-rated pure copper cable (no copper-clad aluminum / CCA)
• Flexible J1127 jacket for easy routing and durability
• Solid copper ends with gas-tight electromechanical crimps (rated for 700 lbs pull force)
• Marine-grade heat shrink (MIL-I-23053/4) for superior corrosion and moisture protection
• Military-style corrosion-resistant battery terminals
• Clearly labeled ends for straightforward installation
• Includes ANL fuse and holder

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 starter lug
• Battery Positive Crossover Cable (2/0)
• Starter to Starter Relay (10GA)
• 2 sets of military-style battery terminals

Important Fitment Note: Some 7.3 trucks use a 90° starter connection (common on OEM starters), while others use a straight connection (typical of Denso and many high-torque aftermarket starters). This kit is the straight starter lug version. Verify the style on your starter before ordering.

Upgrade your 7.3’s electrical system with cables that restore full current delivery, improve cold starts, and eliminate many of the electrical gremlins caused by aged or compromised factory wiring.
