Charge 36in 4-Gauge w/Boot

The Charge 36in 4-Gauge w/Boot from TUFF-STUFF is a heavy-duty battery cable assembly engineered for high-amperage electrical system upgrades and custom vehicle modifications. Whether you're installing a high-output alternator, upgrading to auxiliary batteries, or rewiring a performance electrical system, this 36-inch 4-gauge cable provides the current-carrying capacity and durability that serious automotive enthusiasts demand. The integrated boot protects connections from corrosion, moisture, and accidental shorts—critical safeguards when working with 12V or 24V systems carrying hundreds of amps.

At 4-gauge (AWG), this cable is rated for sustained high-current delivery across distances up to 36 inches without excessive voltage drop—a key consideration when routing power from battery banks to distribution blocks, inverters, or auxiliary charging systems. The rubber or silicone boot covering the terminal ends resists UV degradation, oil, coolant, and thermal cycling, extending service life in engine bays where temperature swings and chemical exposure are constant. The 36-inch length accommodates typical battery-to-alternator runs or battery-to-junction-block installations in trucks, SUVs, and custom hot rods where stock cable routing is insufficient or relocated components demand longer runs.

This cable assembly is ideal for dual-battery builds, lift-gate winch systems, high-amperage audio amplifier installations, and engine swap projects where OEM wiring harnesses no longer meet electrical demands. Installers benefit from the pre-molded boot, which eliminates the need for heat-shrink or secondary insulation and ensures professional-grade termination on the first attempt. Verify terminal lug sizes match your battery posts and distribution block connectors before purchase; 4-gauge cables typically accept 3/8-inch or 5/16-inch lugs depending on the specific terminal design. For permanent installations, solder and crimp all connections, then secure cable runs away from moving engine components and sharp edges.
