Replace your worn-out factory battery cables with a premium Big 7 upgrade kit for Ford Bronco and restore the power your vehicle was meant to have. This complete battery cable kit is designed to deliver faster starts, improved electrical performance, and long-term reliability.
Factory cables weren’t built to last. Ours are built to outlast your truck.
The stock kit does not include an alternator cable.
Why Upgrade Your Bronco Battery Cables?
Over time, factory battery cables break down due to corrosion, heat, and environmental exposure. That loss of conductivity leads to:
- Slow or hard starting, especially in cold weather
- Weak charging performance
- Electrical issues or “gremlins”
- Voltage drop between battery and starter
If your Bronco feels sluggish when starting or has inconsistent electrical performance, your cables are likely the problem.
What makes Big 7 Kits Different?
We build cables for people who care about doing it right. Every component is selected for durability, conductivity, and real-world performance.
Premium Materials and Construction:
- Pure copper, fine-strand SAE-approved cable (no CCA junk)
- Crimped with a high-force electromechanical crimping system
- Solid copper lugs for maximum conductivity
- Marine-grade adhesive heat shrink (MIL-I-23053/4 compliant)
- Military-style, corrosion-resistant battery terminals
Built for Real Use:
- Handles heat, moisture, salt, and off-road conditions
- Designed for long-term durability and reliability
- Each cable labeled for straightforward installation
Do You Need A Bigger Alternator?
No. This upgrade improves efficiency across your existing system.
By restoring proper current flow, your Bronco can:
- Start faster
- Charge the battery more effectively
- Eliminate common electrical issues caused by poor wiring
This is one of the most impactful electrical upgrades you can make without modifying your charging system.
Not Your Average "Big 3" Upgrade!
This isn’t a basic upgrade kit. This is the Big 7 system, designed to replace multiple critical cables in your Bronco’s electrical system for a complete performance improvement.
Built by the original team behind JeepCables, now Big 7 Kits.
