Overview

Upgrade your Jeep Wrangler’s braking system with the Rock Krawler Long Travel Stainless Steel Rear Brake Lines, engineered specifically for 2007 to 2018 models equipped with 3.6L or 3.8L engines. Designed for off-road enthusiasts and daily drivers alike, these brake lines deliver enhanced durability and superior performance compared to factory rubber lines. They provide a firmer brake pedal feel and resist expansion under pressure, ensuring consistent and reliable stopping power even in the most demanding trail conditions.

Whether you’re tackling rugged terrain or navigating tight trails, these brake lines offer peace of mind by maintaining brake system integrity and responsiveness. Their robust construction also offers excellent corrosion resistance, making them ideal for harsh environments where moisture, mud, and debris are common.

Key Features

The Rock Krawler Long Travel SS Rear Brake Lines combine advanced materials and thoughtful engineering to improve your Jeep’s braking system. Key features include:

• High-quality stainless steel braided construction for superior strength and durability
• Enhanced resistance to expansion under pressure, resulting in improved brake pedal feel
• Long travel design to accommodate suspension articulation and extended wheel travel
• Excellent corrosion resistance for longevity in wet and off-road conditions
• Flexible yet robust lines that maintain integrity during extreme off-road articulation
• Direct fitment for 2007–2018 Jeep Wrangler models with 3.6L or 3.8L engines
• Improved safety and confidence with consistent brake performance on and off the trail
• OEM-style fittings for straightforward installation without modifications

Construction & Design

Rock Krawler’s brake lines are crafted from premium stainless steel braid wrapped around a durable inner hose, providing a perfect balance of flexibility and strength. This construction prevents the hose from expanding under hydraulic pressure, which is a common issue with factory rubber lines that can lead to a spongy brake pedal feel. The stainless steel braid also acts as a protective shield against abrasion, cuts, and environmental damage.

The long travel design ensures that the brake lines can accommodate the increased suspension movement typical of lifted or modified Jeep Wranglers, preventing stretching or kinking during articulation. All fittings are precision-machined to meet or exceed OEM specifications, ensuring leak-free connections and reliable performance.

Installation & Fitment

Installation of the Rock Krawler Long Travel SS Rear Brake Lines is straightforward for anyone with basic mechanical skills. These lines are designed as a direct replacement for the factory rear brake lines on 2007–2018 Jeep Wrangler models with 3.6L or 3.8L engines, requiring no special tools or modifications. Simply remove the old lines and install the new stainless steel lines using the included fittings.

Because of their long travel design, these brake lines are especially beneficial for vehicles with lifted suspensions or upgraded long travel setups, ensuring that brake line length and flexibility keep pace with suspension articulation without compromising safety.
