Thumbnail Filmstrip of 7.3 Powerstroke 2/0GA Battery Cable Kit Straight Starter Lug Big7Kits Images
NOTE: Some trucks will have a 90* connection at the starter, some will have a straight connection (such as Denso or other high torque). Be sure to verify which your truck has.
If your Ford Powerstroke 7.3 Diesel F250 or F350 is struggling with slow starts or inconsistent electrical performance, the issue may not be your battery—it could be your cables. This upgraded battery cable kit replaces worn-out factory cables, restoring full power delivery for faster starts, improved performance, and long-lasting reliability. While factory cables weren’t built to last, our heavy-duty kit is designed to outlive your truck.
Why you need these cables:
- Cold weather starts take longer because old cables can be corroded, reducing current flow to the starter.
- Previous owners may have installed subpar wiring, leaving your truck vulnerable to electrical issues.
- Corrosion and age can compromise your vehicle’s entire electrical system.
- Specifically designed for Ford Powerstroke 7.3 Diesel F250/F350 models for a seamless, worry-free installation.
What makes these cables truly special? We focus on precision and quality, using only fine-strand, SAE-approved pure copper cable—never CCA or cheap alternatives. Each solid-copper end is crimped with a powerful electromechanical machine and sealed with marine-grade heat shrink that meets MIL-I-23053/4 standards for maximum environmental protection. The kit also includes military-style corrosion-resistant battery connections, an ANL fuse and holder, and clearly labeled ends to make installation simple.
You don’t need a bigger alternator to enjoy the benefits. Our “better than factory” cables improve battery charging, enhance starting reliability, and often eliminate electrical gremlins caused by old, compromised wiring. With this upgrade, your truck starts faster, performs better, and gains a wiring system that’s built to last for years to come
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

The Big 7 cables see good quality and well insulated. But in my 2000 7.3L PSD the red cables are too short. They will work but they will not route through the factory location. So, you will have to change the location a bit especially the main power cable. The ground cables are fine. It is the power cables that have issues. The power cables on the right battery do not have the bend to make them sit right on the battery terminal. But they do make a large difference on the first day's start up as can be seen in this video: https://youtu.be/GXaJOES39qI
