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 sell 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*.
2/0GA? What's that? That sounds big! Do I need that?
If you like to order the biggest steak on the menu, run 42" Trepadors on your stock axles, or like to flex on your friends, these are for you. You probably don't need them, but we've got them for you.

I wish there was a better connection/fit for the starter, the lug is too large.
Just installed the big 7 kit on my '96 xj. This kit is user friendly and very well labeled to limit confusion. There are also many YouTube videos out there for reference. I went with the heavier 2 gauge cables because I upgraded to a 136 amp zj alternator at the same time. A few more tips; I found the best place for the included fuse block was mounted on the side of the fender next to the battery and pdc. Also, the cable connector to the alternator won't fit into the factory plastic insulators on the alternators because it's too thick (at least on the 2 gauge kit) so I just removed it and attached directly to the alternator but it may need to be heavily wrapped in electric tape or some other way to protect the now exposed connection. There was also confusion at the starter because on my xj the starter power cable and smaller computer wire are both part of the same plastic harness that attaches to the starter. So I just snipped off the old starter cable at that harness, reinstalled it on the starter, and installed the new cable over the top of it. All in all I Highly recommend these kits!
Had trouble with my 94 XJ since bought it.
It would cranks slow and often needed to be jumped off.
This kit completely got rid of all my problems.I'llbr buying another set for my 93 2 door.
Pricing is good I think the price for them to loom the wires was a little to much so I did it myself for significantly cheaper but everything was high quality and fit great and labeled nicely
The cables were just as advertised very nice. Definitely a great upgrade.
