Nice and flexible wire
Size: 2 Gauge Cable, Color: 20 ft Black + 20 ft Red
This feels like nice wire and pure copper which is worth the extra cost. I was able to route this along the frame and around other wires with no issues, well at least not the fault of the wire. The insulation seemed to hold up with no issue as I pulled and re-routed it a few times. I haven't used the winch yet, so I can't say how the wire has held up under heavy load but I hope to soon so stay tuned. Have fun!

Very impressed with quality
Size: 2 Gauge Cable, Color: 20 ft Black
Quality, pliable and exactly what I was hoping for. I used it for a remote negative terminal kill switch. I have a C10 and Ran the cable from the negative terminal into the cab to a 12-volt kill switch and then back out of the cab to a ground on the frame. I would definitely recommend the cable and use it again.

Will buy again
Size: 4/0 AWG 10FT Red & Black, Size: 4/0 AWG 10FT Red & Black
Excellent . Bought these to install a 5000 watt inverter . Arrived a little late but these cables are exactly as described. I needed 10 ft but ended up using like 9 ft. These are extremely flexible and of very good quality . Highly recommended and will buy again
