Faster Starts. Stronger Power. Built Better Than Factory.
This Big 7 Battery Cable Upgrade Kit for the Ford Power Stroke 6.7L Diesel (2011–2016 F‑250/F‑350) replaces aging, worn‑out factory battery cables with high‑quality upgraded wiring designed to deliver more power, improved electrical performance, and faster, more reliable starts.
Factory battery cables were never designed to last the life of a diesel truck. Years of heat, corrosion, moisture, and vibration restrict current flow, leading to slow cranking, weak charging, and electrical issues. Our Big 7 kit restores clean, efficient power delivery throughout the entire electrical system.
Built to outperform factory cables—and likely outlast your truck.
NOTE: Some trucks use a 90° starter connection, while others use a straight connection. Verify your configuration before ordering.
Why Upgrade Your Battery Cables?
If your Power Stroke cranks slower in cold weather, struggles to start consistently, or has unexplained electrical problems, the issue is often hidden inside the factory wiring.
Over time:
- Internal corrosion reduces current flow
- Voltage drop increases under load
- Prior owner repairs introduce resistance and failure points
Upgraded battery cables eliminate these weak links and allow full current to reach the starter and electrical system when it matters most.
What Is the Big 3 — and Why This Is the Big 7?
A traditional Big 3 upgrade improves three cables:
- Alternator output to battery positive
- Battery negative to chassis
- Engine ground to chassis
The JeepCables Big 7 goes further by also upgrading:
- Battery positive to starter
- Battery positive to solenoid
- Battery positive crossover cable
- Starter to starter relay cable
- External MEGA fuse and holder
This prevents increased current from being forced through undersized factory fuse box wiring, improving both reliability and safety under high electrical loads.
What Makes These Cables Different?
We focus on materials, specs, and long‑term durability.
- 100% fine‑strand, SAE‑approved pure copper cable
No copper‑clad aluminum. No mixed metals. - Solid copper lugs, machine‑crimped
Electromechanical crimping creates gas‑tight, vibration‑resistant connections. - Marine‑grade environmental sealing
Adhesive heat shrink meeting MIL‑I‑23053/4 protects against moisture, corrosion, and heat. - Military‑style battery terminals
Corrosion‑resistant terminals included. - MEGA fuse and holder included
External circuit protection built into every kit. - Clearly labeled cable ends
Straightforward installation for DIY owners and professional shops.
Do I Need a Bigger Alternator?
No.
Even a stock Powerstroke benefits from improved power delivery. Reducing resistance and voltage drop allows your existing alternator and batteries to work more efficiently.
Customers consistently report:
- Faster starts
- Improved charging performance
- More stable voltage
- Electrical issues resolved after installation
Planning Accessories or a High‑Output Alternator?
This kit is ready.
If you are running or plan to run a winch, auxiliary lighting, air compressor, inverter, upgraded audio system, or a larger alternator, the Big 7 provides the current capacity and wiring integrity required for higher electrical demand.
Big 7 Cable Kit Includes:
- Battery negative to fender grounds (4 GA)
- Battery negative to engine block grounds (2/0 GA)
- Battery negative to frame grounds (4 GA)
- Battery positive to solenoid (2 GA)
- Battery positive to starter (2/0 GA)
- Battery positive crossover cable (2/0 GA)
- Starter to starter relay (10 GA)
- Two sets of military‑style battery terminals
Important Fitment Note
Some trucks use a 90‑degree starter connection, while others use a straight starter connection.
Please verify which connection style your truck has before ordering to ensure proper fitment.
Not Just a Diesel “Big 3”
This is not a generic diesel cable kit.
This is the Ford Powerstroke 6.7 Big 7 Battery Cable Kit from JeepCables, engineered to upgrade every critical high‑current path in your truck.
Better than factory. Built to last. Designed for Power Strokes that work hard and stay on the road.
