GM Rear Flex Hose w/ Block

The RIGHT STUFF DETAILING GM Rear Flex Hose w/ Block (part number FH06) is a direct replacement brake hose assembly engineered for General Motors A-Body vehicles manufactured between 1967 and 1972. This rear brake hose features flexible rubber construction with an integrated block fitting, designed to meet OEM specifications for safe, reliable hydraulic brake fluid delivery to rear brake components.

The assembly measures 21.45 inches in total length and carries a lightweight profile of 0.29 pounds, making installation straightforward on original or restoration builds. The black rubber hose resists UV degradation and maintains flexibility across the temperature range typical of street and light performance use. The block fitting provides secure attachment points at the frame bracket and wheel cylinder, eliminating flex points that can degrade brake response over time. Replacement is essential when original hoses show cracking, bulging, or weeping—conditions that compromise brake pressure and create safety hazards during braking.

This hose is the correct choice for restoration specialists, classic car enthusiasts, and mechanics rebuilding original brake systems on 1967–1972 GM A-Body platforms including Chevelle, Malibu, and El Camino models. Proper brake line condition is non-negotiable for vehicle safety and inspection compliance. RIGHT STUFF DETAILING specializes in brake system components, and this rear flex hose maintains OEM geometry and pressure ratings for stock or mildly upgraded brake systems.
