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 sometimes called "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.

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.

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! An excellent upgrade for Toyota Tacoma owners planning future electrical modifications. These heavy-duty cables help provide the reliable power needed for demanding accessories and off-road equipment.

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" Swampers 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.

These aren't just any old Tacoma "big 3" cables, these are the "Big 7" from Toyota 4Runner Big 7 Battery Cable Kit!

Replaces 82122-04041, 82122-04042, 82122-04051, 82122-04052

For some of the Toyota kits there’s only two factory negative cables to replace

Sleek Design That Hides Cables Well
Color: White, Size: 3FT(13A), Color: White, Size: 3FT(13A)
This flat plug extension was super easy to set up and works exactly as expected. We mounted it on drywall using anchors (not included), but that wasn’t an issue since we already had some. The flat plug design is great for tight spaces, and it really helped clean up our bedside area by keeping cables neatly hidden and organized. Definitely a practical and space saving solution!
