This kit is made to upgrade your factory positive and negative wires to increase your cars electrical system. By increasing the size of the wire, it will raise the alternators output voltage which will improve everythings performance that uses the 12 volt system. For example, ignition, steering, stereo, headlights, etc. When we installed this on our shop Sonic it bumped the voltage .3, other people have reported more. We are not tricking the alternator to put out more voltage, we are just allowing the full voltage from the voltage regulator to make it to the fuse panel and battery. Whatever output voltage you have must have a better ground as well, so we include 2 upgraded ground wires as well.

The Cruze comes with 1 less wire than the Sonic.

Note: The Sonic uses a battery current wire sensor that attaches just below the battery on the negative terminal. The main ground wire going to the battery must be routed through this sensor (looks like a big hook).

Big 3 Kit

Was having problems with the negative battery cable on my 2011 Chevy Cruze Eco and this fixed that problem. Was fast delivery and a great product for a reasonable price

Excellent Quality!

Excellent quality materials used for the Big 3 (Cruze) Kit! This will help prep my system for the updated audio amplifier I'm going to install. If you have subs, I'd recommend this kit.

Cruze is only 3 but

Everything was a nice quality. Installed without any issues. No noticable difference but peace of mind knowing the charging system is giving and getting all it can.

ZZP Big 4 Wire Upgrade

Made a huge difference, no more lights flickering and my alternator stays steady at 14.4v with a load where as before it was 13.8-14.1v
