Rubicon Express Brake Line Extension Kit for Lifted Vehicles

A suspension lift changes the geometry of your entire brake system — and factory brake lines simply aren't designed to handle the increased distance between the chassis and axle. Rubicon Express Brake Line Extension Kits are purpose-built to restore safe brake line routing and maintain confident, reliable stopping power across the full range of suspension travel on lifted vehicles.

The Rubicon Express lineup includes two solution types to fit different applications and build preferences: stainless steel braided flexible replacement lines and hard line extension kits with couplers and all required hardware. Both are engineered to the same high standards that have made Rubicon Express a trusted name in off-road suspension since 1996.

Key Features:

• Two solution types available — choose stainless steel braided flexible replacement lines or hard line extension kits with couplers and all necessary hardware, depending on your application and preference
• Stainless steel construction — braided line variants feature a thick stainless steel outer casing over a rubber and Kevlar-reinforced housing with a smooth-flowing Teflon inner hose for superior durability and pressure resistance
• Firmer, more responsive pedal feel — stainless steel braided lines resist expansion under pressure, delivering improved braking response compared to OEM rubber hoses
• Hard line extension kits include pre-formed hard line extensions, couplers, and all necessary hardware for a clean, secure, factory-quality installation
• Lift-specific engineering — each kit is designed to provide the correct additional length for a specific lift height range, ensuring proper brake line routing throughout full suspension travel
• DOT-compliant — built to meet or exceed federal motor vehicle safety standards
• ABS compatible — stainless steel line variants are designed for use with ABS-equipped vehicles
• Limited lifetime warranty — backed by Rubicon Express against defects in materials and workmanship

Rubicon Express was founded by Jeep enthusiasts and is located near the Rubicon Trail, where products are real-world tested to ensure the highest quality, safety, and performance. Select the correct kit for your specific lift height and front or rear application to ensure proper fit and safe brake system operation.
