These alternator power cables and engine ground cables come in one thickness #2 AWG cable.
Replacing your 30+ year old cables provide the following:
-Decrease alternator and starter strain by providing higher current flow to operate.
-Increased stability of electrical system
-Increased stability and current handling of car stereo amplifiers by providing quicker current draw.
-Old corroded, oxidized, greasy, worn ground cables will cause issues such as intermittent starter operation, inaccurate temperature gauge, and dimming head lights.
-Our 2 AWG kits provide faster crank times by allowing the starter to pull more electrical current resulting in reduced engine crank over!
Our cables are made to the highest quality standards using the highest quality products. Every aspect of our cables is superior to the competition, even the shear weight of our cables will exceed any other cable on the market! Once you receive your new cables in the mail, in a heavy box, you will see what I mean!

Here are the specs of the cable and components that I used:
Cable Conductor - 99.999% purified electrolytic copper
Cable Insulation - Royal Excelene (resists oil, chemicals, water, ozone & solvents and is rated at 600 volts/3 hours, -58F to 221F)
Lugs - 99.99% Copper 3/8in dia through hole
Heat shrink - Irradiated Polyolefin (flame retardant, -58F to 221F)
Please note: All cables now come with tinned lugs and there is no bare copper anywhere.
Additional specs - Highly flexible welding cable, which in my professional opinion, is the best power cable because its resistant to multiple climates, temperatures, oils, gas, and can withstand extreme amounts of current. Also highly conductive copper.
I am a professional electrical technician for over 20+ years so I can assure you these cables are made with the utmost quality and will provide reliable power transfer for decades to come. Here are the steps that I used to build these cables.
Insulation is stripped, using professional techniques that avoids ANY possible nicks or scores. Wire that is stripped in a un-professional manner will have nicks and scores that will break over time and/or during the moment of crimping. This will lead to failure of the termination.

First crimped using INDUSTRIAL STRENGTH crimpers under high pressure.

Polyolefin heat-shrink tubing applied
Each termination is cleaned for maximum conductivity.
