7.3 OBS Powerstroke 2/0GA Battery Cable Kit – 90° Starter Lug Big7Kits | FPSD90-73-00G-90

Upgrade the electrical system on your 1990–1997 Ford F-250/F-350 7.3L Powerstroke with this complete Big7Kits battery cable kit. Factory cables degrade over time from heat, corrosion, and vibration, leading to slow starts, voltage drop, and unreliable charging. This heavy-duty 2/0GA kit restores full current flow for faster cranking, stronger charging, and improved overall electrical performance.

Why This Kit

• Built with fine-strand, SAE-approved pure copper cable (no CCA)
• Precision electromechanical crimps for gas-tight, high-conductivity connections
• Marine-grade heat shrink (MIL-I-23053/4) for superior corrosion and environmental protection
• Military-style battery terminals for secure, reliable connections
• Labeled ends for straightforward installation

This is a true “Big 7” upgrade—not a basic big-3 set—engineered to outlast the truck and deliver consistent power delivery even in demanding conditions.

Kit Includes

• Battery Negative to Fender Grounds (4GA)
• Battery Negative to Engine Block Grounds (2/0)

Fitment

1990–1997 Ford F-250 / F-350 with 7.3L Powerstroke (OBS)

Important: Some trucks use a 90° starter connection while others (including certain Denso or high-torque aftermarket starters) use a straight lug. Confirm the style on your starter before ordering.

Give your OBS Powerstroke the reliable starting and charging performance it deserves with a properly engineered cable upgrade built for longevity.
