In a race car, electrical failure is often just a vibration or a heat cycle away. Standard primary wire from a local hardware store isn't designed to survive the engine bay of a Dirt Late Model or the cockpit of a GT racer. The Longacre 52-44957 16-Gauge Heavy-Duty Electrical Wire is a professional-grade wiring solution engineered specifically for high-stress motorsport applications.
Finished in a clean Black jacket, this 16-gauge wire strikes the perfect balance between current-carrying capacity and flexibility. It is the ideal gauge for mid-range electrical loads like gauge illumination, sensor signals, transponders, and low-draw accessory triggers. Built with a high strand count for superior flexibility and a rugged insulation jacket that resists oil, grease, and gasoline, this wire ensures your critical systems stay powered from the green flag to the checkered.
Key Features
-
High-Strand Count Flexibility: Engineered to withstand constant chassis vibration and G-loads without work-hardening or snapping—a common failure point in lower-quality solid or low-strand wires.
-
Chemical-Resistant Insulation: The heavy-duty outer jacket is specifically formulated to resist degradation from racing fuels, motor oil, brake fluid, and engine degreasers.
-
16-Gauge "Sweet Spot": Provides ample current capacity for most racing electronics while remaining thin enough to be easily routed through tight firewalls and into multi-pin connectors.
-
Heat-Stabilized Jacket: Designed to maintain its structural integrity in high-temperature environments, preventing the insulation from becoming brittle or melting near heat sources.
-
Professional Black Finish: Ideal for main ground circuits or discreetly routing power lines through the interior for a clean, "factory-stealth" look.
