Flexline Kit D154 10in x 3/8-24 IF 10mm Banjo

The Wilwood Flexline Kit D154 10-inch 3/8-24 IF 10mm Banjo is a DOT-approved braided stainless steel brake hose assembly designed for high-performance and custom vehicle brake system applications. This 10-inch flexline kit delivers reliable hydraulic fluid transfer with corrosion-resistant construction, making it suitable for both street and track-oriented brake upgrades where demand for durability and consistent pressure delivery is non-negotiable.

The kit features a 3 AN straight inlet and 3 AN straight outlet configuration, enabling straightforward integration into existing brake line architectures. The braided stainless steel construction resists abrasion, vibration wear, and environmental corrosion—critical factors in vehicles subjected to aggressive driving conditions or prolonged exposure to salt spray and moisture. The 10mm banjo fitting and 3/8-24 IF thread specification ensure secure, leak-free connections at both termination points. Wilwood's engineering focuses on pressure stability and response consistency across the full operational temperature range, which directly impacts braking modulation and pedal feel under sustained or repeated deceleration cycles.

This flexline kit is engineered for rear brake line applications in universal and custom brake system builds. Buyers upgrading to performance calipers, increasing brake pad compound aggression, or relocating brake components benefit from the hose's ability to withstand elevated system pressures without ballooning or performance degradation. Installers and fabricators frequently select Wilwood flexline kits during full brake system overhauls where OEM rubber lines cannot meet performance targets or where routing flexibility is required around modified chassis layouts.

Wilwood maintains a strong reputation in the aftermarket brake systems segment, with products widely adopted in circle-track racing, road racing, and street performance applications. DOT approval confirms this hose meets federal safety standards for highway vehicles, while the braided stainless design addresses the durability expectations of serious hobbyists and professional fabricators alike.
