Jeep Grand Cherokee WJ Big 7 Battery Cable Kit (1999-2005)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 "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

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 "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 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. Built to the same exacting standard, our Jeep Wrangler JK 3.6L (2012-2018) kit delivers this same pure copper quality engineered for later generation Wranglers.

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 4GA? Which to choose?

As far as 2GA vs 4GA, it's really going to depend on what mods you're going to do to. If you're staying stock, then 4GA is plenty, but if you're looking at modifying it down the road (winches/lights/etc) then you'd want 2GA, and we all know a Jeep is never really *done*. Get better starting power with the Jeep Grand Cherokee 4.0L (1999–2004) upgrade cable kit.

Quick read, entertaining & informative
Format: Hardcover
This book can be enjoyed on several levels. It could be tongue-in-cheek or satire, but is also backed by facts and conjecture by one of the world’s greatest scientific thinkers. I think Dr. Tyson had fun writing it, and i certainly had fun reading it. And I learned a lot.

Aliens: Know what to expect!
Format: Audiobook
This is a really fun review of Earth's obsession with alien life, what we have historically expected of aliens--and what they might expect of us. If you are a long-time listener of the author or a viewer of his YouTube show (Star Talk), you have probably heard much of what NDT has to say on this subject already--here and there as he picks his way thru the universe, but why not listen to him now again as he focuses his energies on just this alien subject? If you want an enjoyable read, it will be worth your time. If you're not a long-time listener of NDT... and you have any interest in aliens at all, then you DEFINITELY should give this book a go. It is full of thoughtful insights from a man who has devoted his life to the science and 'cultural impact' of the stars. I listened to the Audible version wherein NDT reads his own book aloud for you. His efforts really allow you to gain his insights... And his strong sense of humor--in equal doses. 5 Stars

My son is actually motivated to do a workbook
Format: Paperback
My Kindergartener finished homeschool online early and we have been doing a page a day and he loves it and loves to earn a sticker after each day and put it on his chart. I love how engaging the workbook is and how it introduces some 1st grade concepts. Would highly recommend.
