70-78 GM 5-8in Lift Frt. Brake Lines

The 70-78 GM 5-8in Lift Frt. Brake Lines by SKYJACKER are engineered specifically for lifted Chevrolet and GMC trucks and Blazers that require extended front brake line routing. When you lift a vehicle 5 to 8 inches, factory brake lines become too short to safely reach the calipers without binding or kinking during suspension articulation. These extended lines solve that critical clearance issue, ensuring your braking system maintains proper hydraulic pressure and responsiveness throughout the full range of suspension travel. Whether you're building a classic K5 Blazer or a Chevy pickup with modern suspension geometry, proper brake line length is non-negotiable for safety and reliability.

SKYJACKER's front brake line kit features high-quality steel construction with DOT-compliant fittings that prevent corrosion and fatigue cracking under repeated brake pressure cycles. The lines are pre-bent and tested to fit precisely within the 5- to 8-inch lift range, eliminating the need for custom bending and reducing installation time significantly. The design maintains factory-style connector points while adding the necessary additional length, so integration with your existing master cylinder and proportioning valve remains straightforward. Proper brake line routing also minimizes vibration transmission to the pedal and reduces the risk of line rupture from suspension movement or debris contact.

This brake line kit is essential for anyone installing a SKYJACKER lift kit or any comparable 5- to 8-inch suspension lift on 1970–1978 Chevy C10, K10, Blazer, or GMC equivalent models. Installation pairs seamlessly with coil-spring or leaf-spring lift systems and works in conjunction with extended tie rods, drop pitman arms, and adjusted brake proportioning for optimal stopping performance. Mechanics and DIY enthusiasts appreciate the OEM-quality construction and precise fitment that eliminates guesswork; simply disconnect the factory lines, route the new ones, and bleed the system. For serious truck builds where suspension geometry has been modified, these lines are a safety-critical component that ensures consistent braking feel and safety margin under all driving conditions.
