This Cable Bundle does NOT include the Auxbeam Essential PowerTray or the Auxbeam Unit. Those are separate products. This Cable bundle is for upgraded 4 gauge cables only. Why should you upgrade? Our cables are made from high grade USA made welding cable. Welding cable uses pure, ultra-fine copper strands for maximum flexibility and electrical conductivity. Copper-clad aluminum (CCA) features an aluminum core with a thin copper coating, making it lighter and cheaper, but with significantly lower conductivity, higher resistance, and a higher risk of corrosion. Simply put, the pure copper makes the power flow easily and safely. 2 Premium USA Made Power Cables 30" Length 4 Gauge Power Cable (Battery terminal to Auxbeam Breaker) 14" Length 4 Gauge Power Cable (Auxbeam Breaker to Auxbeam) 1 Premium USA Made Ground Cable 26’’ Length 4 Gauge Ground Cable (Auxbeam to Fender Ground) Features: All battery cables are made in house with high quality, USA made welding cable.
