Big 3 upgrade 4 gauge OFC
I ordered the big 3 kit and it shipped same day arriving 2 days from date of purchase. Super fast service and no issues with any of the products received. Skyhigh 4 Gauge OFC is bigger than the stinger 4 gauge CCA kit I had previously installed. I highly recommend Skyhigh.

best 4 awg ever made
I bought the wire thinking it was going to be the average 4 awg kit but i was wrong its is thick, durable, and has many color options which is pretty cool. I installed it and noticed a huge difference plan on ordering more from sky high.
