Description

The factory cable sets leave lots to desire with thin wall terminals and lugs.  In addition, none of the terminations are insulated from the elements which causes them to break down over time.  Common problems with these trucks are decreased starting performance and grounding issues.  Our kits address both fully.

  • Unisex Side Post Battery Terminals – three times as thick as the originals

    This kit was great! The cables are very well made, the perfect length and the instructions were clear. I went with the 1/o and was not disappointed cranking power has increased greatly and fixed many of my light flickering problems, my heated seats work again, my radio doesn’t cut out anymore and i have amp research power running boards that would go up half way or not at all that now work great. the only problem i had was while hooking the cable to starter the tab was slightly too big and would engage the starter but a simple modification took care of that. If you’re thinking about getting this kit just do it, it’s definitely worth the money i couldn’t be more pleased with the quality of the the kit or the results!

    The cable kit that I received was exactly as advertised and shown. Definitely not the cheapest option but without a doubt more value per dollar spent. The quality of materials and construction is worth what CE Auto Electric is asking. All the terminals are rock solid and where the cables split there are 3 mechanical devices holding them together, the terminal, glue lined heat shrink (very thick heat shrink) and a zip tie to make sure. All jackets are secured in place via heat shrink and heat shielding is where it needs to be. The battery terminal hardware is bagged and labeled, the ground bolts have had the washers put on the and twist tied to keep them together. All other nessary hardware is included and the installation instructions are clear and cover everything needed to install my new larger cables.

    Really can not say enough about this kit or the customer service from CE Auto. If you want and can appreciate buying from a company that still believes in customer care, buy from CE auto.

    I purchased the 1/0 kit. The cables cleared up my dimming lights when using my power windows and the slow rolling power windows. Their ground wires correct many of GMs faulty ground issues and the cables look bad Azz! Do yourself the favor !

    I wish I could give them Ten stars …as an electian and carpenter by trade I was going to make my own cables ….wow i’am so glad I just did the upgrade on the cables as these new 1/0 cables are big and put the stock GM cables to shame

    Anyone looking at this kit has probably already figured out that these year GM trucks have poorly designed battery cables. Factory Terminal ends are susceptible to water/moisture intrusion causing them to corrode and rot from the inside out.
    I live up north in Maine where below freezing temperatures are frequent for several months out of the year. I had very weak cranking power and hard starts on most mornings during the winters, even when using the block heater overnight. So I replaced both batteries thinking that would solve my problems but I had little to no gain in cranking power after installing them so, I started looking at the cables next. Which is where I found my issue. Once removed, you could feel how brittle the wires had become and see how corroded the cables were at the terminals. Knowing I had to replace them, I decided to cut into some of the wires to find they were plagued with heavy corrosion. I didn’t want to replace them with OEM cables, I wanted something better and figured there was no better time to upgrade than now.
    There are very few aftermarket companies who make a complete kit specific to the Duramax. Especially ones that address all the OEM flaws and with the option to go bigger with 1/0 gauge wire for maximum cranking power like this one. So, I took a chance and ordered the upgraded 1/0 version.
    This kit is the cure!
    Heavy duty terminals lugs are crimped properly with thick, adhesive lined shrink wrap that keeps moisture out of your wires and terminations. All the terminal lug eyelets were the proper size for their corresponding hardware that’s included with the kit and all wires were the right length so there are no headaches!
    I bought the 1/0 gauge kit back in November before the really harsh cold weather started.
    Through the whole winter, my truck started with ease every single morning no matter how cold. The first time I started the truck after installing the cables, you could VERY clearly hear The difference in starting/cranking power. This kit allows you to send all the power possible from your batteries to get your duramax started and never have to worry again. Now, I have the confidence my truck will start, reliably, even in well below freezing temperatures.
    10/10 would recommend to anyone with a duramax. It’s the best kit you will find out there and we’ll worth the investment!!
