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 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 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 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 4Runner "big 3" cables, these are the "Big 7" from ToyotaCables!

Great product had no issues on installation on my 4Runner! Good fit, good service, and good product. Can’t beat it! Oem wiring for reference.

I bought the 1/0 GA kit, easy install. Be careful with the plastic white bracket under the the front of engine block (going to starter). Slow and steady. Sturdy kit, well made and easy to install.
Give them a call or shoot them an email, the customer service team here is really helpful and will answer your questions. Paul was ready to help!

Cables are heavy duty and thick. Install went smoothly. I didn’t purchase the sleeves due to the ruggedness of the cables.
If you choose the 2ga… keep in mind you will have to fight to get them to bend certain ways for cable management. Also, consider what battery terminals you will want to use.
Fuseblock cable swap was almost impossible to do due to the size of the cables ended up leaving the stock one attached.
One negative, it didn’t come with an ANL fuse.

Great kit comes with everything to replace all the battery cables with everything done already you just need to remove the old harness and run the new cables. Everything is labeled which makes installing easy. I decided to essentially make a new harness using flexible wire loom tubing and electrical tape for a clean and professional installation.

Right off the bat, you can tell these are meant to last! Beefy cables and well put together. My + and - cables were a bit too short to fit the 3rd Gen 4R well --- I saw another review on this too. I contacted them and they humbly resolved it same day by sending me a longer cable. AMAZING customer service, can't be beat. Thank you all!
