Flexline Kit Frt 70-73 Mustang

The Flexline Kit Frt 70-73 Mustang from WILWOOD is a front brake hose assembly designed specifically for first-generation Mustangs (1970–1973) undergoing brake system upgrades or restoration. This kit exists to bridge the gap between modern high-performance brake calipers and OEM chassis routing, ensuring proper hose placement, length, and fitment without modification to frame or body. Whether you're converting to disc brakes, upgrading to a larger bore master cylinder, or installing a complete front brake kit, the Flexline Kit Frt 70-73 Mustang provides the correct brake line geometry that stock rubber hoses cannot deliver reliably under sustained heat and pressure.

WILWOOD's flexline technology uses reinforced stainless steel braiding over synthetic hose material to resist expansion and fluid degradation under high-temperature braking events, critical for performance driving or road racing applications. The kit's engineering accounts for suspension travel and steering lock, preventing hose pinch-points or abrasion against frame components during full articulation. Weighing just 1.07 lbs and engineered to OEM-equivalent lengths and port diameters, the Flexline Kit Frt 70-73 Mustang maintains consistent brake pressure delivery while eliminating the sponginess inherent in aging rubber hoses, resulting in firmer pedal feel and more predictable stopping force.

Classic Mustang builders and enthusiasts installing modern Wilwood brake kits, Baer Systems components, or factory M-code performance setups will find the Flexline Kit Frt 70-73 Mustang indispensable for front end assembly. Installation requires no frame fabrication, making it ideal for restomod projects seeking authentic appearance with contemporary stopping power. Compatibility extends across all 1970–1973 Mustang models, including Mach 1, Boss, and Grande variants, whether powered by inline-six, 200 CID, 250 CID, or big-block engines. Verify existing caliper mounting and port thread size before ordering to ensure seamless integration with your brake system upgrade.
