Charging System Upgrade Kits

Product Improvement – All Kits Now Include Translucent Black Ground Cables!

When upgrading your alternator to a unit capable of higher output, it is also necessary to upgrade your vehicle’s wiring. Specifically, it is necessary to upgrade:

  • The charge lead from the alternator output stud to the battery
  • The return path between the alternator and vehicle ground
  • The return path between the battery negative (-) and the vehicle ground

It’s safe to assume that one of the reasons you are upgrading to a high-output alternator is because you’ve added some current-hungry accessories and their requirements are greater than what the stock alternator was able to support. This is not the place to save a few bucks and skimp on cables!

Most “upgrade kits” are nothing more than a larger gauge charge lead. Our charging system upgrade kits assure you that you will get every ounce of performance that your charging system is capable of. They are the only such kits available at any price.

Charging System Upgrade Kit Specifics

As with all of out kits, our charging system upgrade kits include the very best components available. Each kit is incredibly well thought out and installation is a breeze – no crimping or soldering required!

The Best Cable

We use the very best cable we can get our hands on – our own!  It meets full American Wire Gauge (AWG) specification, is Pure Oxygen Free Copper (OFC), and tinned for corrosion resistance. Other companies use Copper Clad Aluminum (CCA) cable in an effort to reduce cost. CCA has 30-40% greater resistance per foot than OFC, so while it may be cheaper, it also comes at the expense of performance.

Battery CableSpecifically, our OFC cable has the following strand count:

  • 1/0 AWG Cable – 4,704 strands!
  • 2 AWG Cable – 2,989 strands!
  • 4 AWG Cable – 1,862 strands!
  • 8 AWG Cable – 735 strands!

The fine-strand construction and soft jacket offer excellent flexibility, far superior to standard battery cable and better than the best welding cable!

The Best Parts

We custom assemble all cables in house, and building the best cable requires the best parts. All eyelets used in the construction of our cables are the heaviest duty in the industry. They have up to twice as much copper weight as standard copper lugs, longer barrels, which permit better crimping, and are tin-plated to resist corrosion. These are simply the best quality eyelets we can find and they are ideal for high current applications!

All eyelets are installed via our crimping press and insulated with the thickest adhesive lined heat shrink available. This super-thick adhesive-lined heat shrink tubing prevents battery acid or oxidation from entering the connection itself.

Additionally, we include a complete assortment of Grade 5 Hardware with each kit. You’ll have every single thing you need to get the job done right the first time. We guarantee it!

Step By Step Full Color Instructions

Each kit includes complete step by step instructions in full color so that your installation goes smoothly! They’re super easy to install and require only common hand tools to install them.
