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 SAE J1127 fine-stranded oxygen-free copper (OFC) cable. Then using a powerful electromechanical crimping machine, we crimp each tin-plated copper lug, and finally finish the construction by adding an environmental seal made of marine-grade dual-wall adhesive-lined heat shrink. 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.

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.

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.
