Upgrade your 1980–1986 Ford Bronco with a high-performance Big 7 battery cable kit for faster starts, stronger charging, and reliable power. Factory cables wear out over time. Ours are built to outlast your Bronco.
Why Upgrade Your Bronco Battery Cables?
Old, corroded cables restrict current and cause:
- Slow or hard starts
- Weak charging performance
- Electrical issues and voltage drop
Built Better Than Factory?
- Pure copper, fine-strand SAE cable (no CCA)
- Heavy-duty crimped tinned copper lugs
- Marine-grade adhesive heat shrink
- Corrosion-resistant military-style terminals
- Labeled cables for easy install
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.
