This upgraded battery cable kit replaces old worn out battery cables for more power and better performance from your vehicle.
What's the Big 3 and why do you make a Big 7?
The "Big 3" or "Big 4" upgrade means improving the current capacity of three cables: 1) alternator output to battery positive, 2) battery negative to frame/body, and 3) engine ground to frame/body. We don't stop there though. Our "Big 7" kits also include 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. It’s really one of the first mods you should do to any Jeep!
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 4GA? Which to choose?
As far as 2GA vs 4GA, it's really going to depend on what mods you're going to do to. If you're staying stock, then 4GA is plenty, but if you're looking at modifying it down the road (winches/lights/etc) then you'd want 2GA, and we all know a Jeep is never really *done*.

United StatesGreat upgrade, but a few downsides...
Love the kit, especially all the stickers it came with. My Jeep starts faster now too! I've had the kit for a minute now, I waited to write a review, the kit is very inclusive, everything was labeled. It took about an hour to install, and looks great. My kit was for the Jeep ZJ with the V8 option. I have a few negatives I'd thought I'd mention. The battery terminals while easy to add accessories too, seem to be cast metal, and mine actually had a pit on the inside. I also had some excess slag hanging off aswell. They're also easy to smush, I tapped mine on as they were a little tight which is good but I put dents where I had tapped, so I was a little disappointed about the finish. Lastly the eyelet on the alternator side was too big and didn't fit in the stock plastic gaurd which protects against arcing, so I had to dremel down the sides of the eyelet, and some plastic off the gaurd (both still completely functional) All in all a great kit, just a few things to watch for.
United StatesGreat product little information
Love the product, kind of a pain to figure everything out. Could use a little more information for the tear down.
