THE BEST BATTERY CABLE SET! This high temperature, cross-link 1-gauge cable is far superior to auto parts store or welding cables. With a temperature rating of 255°F, [under hood temperature varies from 212°F to 240°F] this flexible cable has less voltage drop and more current carrying capacity. The quality lug stays round longer, thus insuring a tight seal and resisting corrosion. The color coded rubber protective boots further clean up your installation for a neat engine compartment. Includes 20' of positive cable and 15' of negative cable. Long enough to mount in the trunk! All battery cables come with a crimping tool, extra lugs and shrink tubing.
