This upgraded battery cable kit replaces old worn out battery cables for more power and better performance from your vehicle.
What is the "Big 7" Battery Cable Kit
Our "Big 7" kits include the standard "Big 3" cables: alternator output to battery positive, battery negative to frame/body and engine ground to frame body PLUS we add the leads to the starter and the fuse relay box, as well as adding an external fuse to avoid routing the increase in current capacity through the smaller fuse box wiring.
What makes these cables so special?
We're nerds for specs and finer details around here. None of that CCA (copper-clad aluminum) that's used in inferior products, or stereo installations. We only use fine-strand, SAE (Society of Automotive Engineers) approved, pure copper cable. Then using a powerful electromechanical crimping machine, we crimp each solid-copper end, and finally finish the construction by adding a environmental seal made of marine grade heatshrink meeting MIL-I-23053/4. Also included are military style corrosion resistant battery connections and an ANL fuse and holder. To make the entire install simpler, every end will be labeled for ease of installation.
Do I need a bigger alternator to run these cables?
No. Every vehicle can benefit from our "better than factory" cables. The years, along with environmental damage from rain/salt water/corrosion, can greatly impact your electrical system. Our customers have consistently reported that their vehicle starts faster, charges the battery better, and many times cured electrical gremlins that were brought on by compromised wiring.
I've changed my mind! I want to run a bigger alternator!
Perfect! You're probably running a power inverter, a stereo, a winch, an under hood welder, or flux capacitor. These all require more amperage than the stock alternator is capable of providing. Maybe you're not running any of these yet, but considering it, these cables will get you ready!
2GA or 1/0 GA? Which to choose?
As far as 2GA vs 1/0 GA, it's really going to depend on what mods you're going to do to. If you're staying stock, then 2GA is plenty, but if you're looking at modifying it down the road (winches/lights/etc) and want to future proof, then you'd want 1/0 GA.

United StatesBe patient, it takes a minute to get them then you open the package and see the quality product your looking at and forget all about how long it took.
I waited for a long time three or four weeks. With that said I opened them up and now don't care about the wait. I haven't run acrossed better quality cables on any site so stop looking and order your set now!!! I had a set on another jeep, sold that jeep after getting another jeep the cable set is the first thing I ordered for my new (17) jeep. A stock jeep would benefit from these let a lone one upgraded there a must. I couldn't be happier with my cable's. Order now takes a long time but you will be happy when you receive them. I was...
United StatesGreat stuff!
Installation was a snap, everything fit as it should. Highly recommended!
United StatesCables for my power plant
Awesome, I run a 2014 wrangler with dual separate compressors, on board welder, 15k *****, too many lights and a 300 amp alternator, optima battery cb etc. And my rig is now a le to take more than i can give. Thanks yall
United StatesWires were huge! . Pretty easy to install. I ended up putting one ground one the engine one to the frame and one to the body.
All I need now is a high output alternator. Still using the stock 160A. Eventually I'll run a 350A.
United StatesPretty sweet
08 wrangler with 3.8L. I love the construction of the wires. I went for the 1/0 gauge to set me up well for future accessories. Only complaint is that I wish an electrical diagram was included. Electrically, the install was easy however physically routing the wires was difficult. Install took me about 6-7 hours start to finish. 2 hours to rip out the old stuff. It took my while to install mostly due to how I wanted the wires to route and make it look semi-clean. I did fab up a copper bracket for the PDC terminal as I didn’t want to cut the box, again I’m going for a clean look. Biggest thing to keep in mind is the 1/0 gauge wire doesn’t make sharp bends well. Overall great addition to the build.
