GM Extended Front Brake Lines

The GM Extended Front Brake Lines (SKU: RCS89360S) are engineered for lifted GM full-size trucks and SUVs from 1987 to 1991 that require extended brake line length to accommodate suspension lifts of 2 to 6 inches. When you raise your vehicle's ride height, the factory brake lines become inadequate—they stretch to their limits, creating excessive stress on fittings and risking line rupture under braking loads. This braided stainless steel brake hose kit solves that critical safety issue by providing the necessary extension while maintaining factory-spec hydraulic performance and stopping power.

Constructed from DOT-approved braided stainless steel, these extended front brake lines deliver superior durability and corrosion resistance compared to rubber hose alternatives. The braided construction withstands the vibration and thermal cycling inherent in lifted vehicles, preventing micro-abrasions that degrade rubber compounds over time. The stainless inner tube resists rust and maintains fluid integrity across a wide temperature range, critical for consistent brake modulation during towing or off-road driving. Each line is pre-cut and fitted to match OEM routing and attachment points, eliminating guesswork during installation and ensuring proper clearance from suspension components and steering linkage.

This kit is ideal for GM truck and SUV owners running 2 to 6-inch suspension lifts—whether coil springs, air suspension upgrades, or body lift kits—who need a reliable, code-compliant solution. The DOT approval ensures these lines meet federal safety standards and are street-legal for highway use. Direct fitment to the front axle of 1987–1991 GM full-size vehicles (C/K pickups and Suburban/Tahoe platforms) means no custom fabrication or adapter fittings required. Installation typically takes 1 to 2 hours with basic hand tools and a line wrench; proper brake bleeding afterward is essential to remove air and restore full pedal feel and stopping power.
