Jeep Commander XK Big 7 Battery Cable Kit (2006-2010)

This upgraded battery cable kit replaces old worn out battery cables in your 2006-2010 Jeep Commander XK for more power and better performance.

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 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 1/0GA? Which to choose?

As far as 2GA vs 1/0GA, 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) then you'd want 1/0GA, and we all know a Jeep is never really *done*.
