This upgraded battery cable kit replaces old worn out battery cables for more power and better performance from your vehicle.

What's the Big 7 Complete Kit?

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 a MEGA 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. This upgrade is especially beneficial for the Jeep Grand Cherokee ZJ (1993-1998), helping restore reliable electrical performance and improve overall system efficiency.

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*.

USB Rechargeable Electric Can Opener
Color: Black
Item review update! Disregard my first review since then I realized that I didn't have the usb cable pushed in far enough for a connection which stopped the item from charging and that's why it stopped working. Item works as described, clean cut, easy to use and really worth the cost. I definitely recommend.

Very Easy to Use, no stress on your hands
Color: Black
I am 76 and my hands don’t grip the way they used to. Too hard using a manual can opener. This one definitely fits the bill, plus I like the rechargeable feature!

Very poor quality. Not supported by manufacturer.
I bought this because of my arthritis. I could not use a manual can opener anymore. Worthless product. It lasted 3 months, only cut soft aluminum cans. No response when I emailed the company. Do not buy this product.
