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

Upgrade your 1990–1997 Ford F-250/F-350 7.3L Powerstroke with this complete Big7Kits 2/0 gauge battery cable kit featuring a straight starter lug. Designed for trucks equipped with Denso-style or other high-torque aftermarket starters that use a straight connection (verify your starter type before ordering — some trucks use a 90° lug).

Factory battery cables on OBS Powerstrokes commonly corrode, work-harden, and create high resistance that leads to slow or hard starts, weak charging, and random electrical gremlins. This kit replaces the entire high-current system with properly sized, pure copper cables built to last.

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

Construction & Features:

• 100% fine-strand SAE-rated pure copper wire (no copper-clad aluminum)
• Flexible J1127 jacket
• Gas-tight electromechanical crimps
• Marine-grade heat shrink (MIL-I-23053/4) for corrosion protection
• Labeled ends for straightforward installation
• Military-style corrosion-resistant battery terminals

This is a full “Big 7” upgrade — not just a basic big-3 set. Expect stronger cold starts, improved charging efficiency, more stable voltage under load, and a cleaner, more reliable electrical system that will outlast the truck.

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

Note: Confirm whether your starter requires a straight or 90° lug before ordering.
