Rough Country Super Duty 4WD Front Stainless Steel Brake Lines - 4.5-6in Lift (2017-2026)

Lifted Super Duty trucks need brake lines long enough to flex with the suspension without binding, kinking, or pulling tight at full droop. Rough Country's stainless steel extended front brake lines replace the factory rubber hoses with a DOT-approved braided assembly sized specifically for 4.5 to 6-inch lifted 2017-2026 F-250 and F-350 Super Duty trucks, restoring proper brake function and adding real durability over stock.

Braided stainless steel construction that handles the abuse. The woven stainless exterior shields the internal Teflon liner from rocks, mud, and trail debris that tear through rubber over time. That same braided layer prevents the hose from ballooning under pressure, keeping fluid transfer consistent and delivering a firmer, more confidence-inspiring brake pedal feel compared to soft, expanding rubber lines.

Pressure-tested to 4,000 PSI. Each line is rated well beyond normal hydraulic braking pressures, so hard stops and aggressive off-road use stay within safe operating margins. High-quality hollow fasteners at both ends create a leak-free flow path from the hard line to the caliper, eliminating the weeping connections that worn rubber fittings develop over time.

Cut to the right length for a lifted truck. At 33.5 inches, these lines provide the reach a 4.5 to 6-inch suspension lift demands without excess slack that could catch on chassis components or pinch points during articulation. Installation takes two to three hours and requires no fabrication or modification to existing brake hardware.
