43in #3 Line -3 Str/-3 Str

The 43in #3 Line -3 Str/-3 Str brake hose by Allstar Performance is purpose-built for high-performance automotive brake systems where reliability and precision matter most. Whether you're building a custom street rod, upgrading a race car's brake plumbing, or restoring a classic vehicle, this braided hose assembly delivers the controlled fluid transfer and durability professional mechanics demand. At 43 inches long with dual 3 AN straight female fittings, it bridges master cylinders, proportioning valves, and wheel cylinders with tight tolerances and zero flex in critical brake applications.

This hose features a stainless-steel braided exterior that resists abrasion, corrosion, and road debris while maintaining structural integrity under sustained hydraulic pressure. The inner PTFE (polytetrafluoroethylene) lining ensures consistent fluid flow and compatibility with DOT-approved brake fluid formulations without degradation or swelling over time. The 3 AN (5/16-inch) port size accommodates moderate brake line diameters commonly found in custom builds and performance applications, while the straight female-to-female configuration allows seamless integration between standard SAE or AN fittings without additional adapters. At just 0.22 lbs, the lightweight construction doesn't compromise structural strength—critical for vehicles where unsprung weight affects handling and stopping power.

Mechanics and fabricators choose this Allstar Performance line for street rods, drag cars, circle-track vehicles, and custom brake system installations where factory components won't fit or meet performance standards. The 43-inch length accommodates medium-distance routing from engine bay to rear axle assemblies, making it ideal for vehicles with custom firewall modifications or relocalized brake components. Installation is straightforward: thread the straight female AN fittings onto corresponding male 3 AN ports, verify hose clearance from exhaust and moving suspension parts, and secure with brake line clamps every 12–18 inches to prevent vibration-induced fatigue. This hose pairs well with adjustable bias proportioning valves, remote master cylinders, and modular brake kits found in comprehensive performance upgrades.
