  • Testimonial

    This is an awesome product. The quality, craftsmanship and fit and finish that went into these cables is second to none. But above all the customer service is tremendous. They are nothing but astute and kind when you call. They will help you with anything from getting the cables installed to making sure you get the correct parts.

    After installing the kit, I noticed that my Jeep started more quickly than before. I’m sure this is because the 25 year old, corroded factory wiring had a ton of resistance to the starter. That upgrade alone is worth the price of admission, but the kit goes beyond that - it gives me some peace of mind that my janky, hack job wiring that I’ve done on the rest of the vehicle won’t burn down my Jeep, the garage, and the rest of my house with it.

    This is my second set, the first set went on my 99 Jeep WJ. It is nice to be able to refresh the old OEM cables with something that is better. How many electrical demons are related to bad grounding that naturally occurs on any vehicle. I always feel good knowing that the much of the heavy electrical system is in a good place.
