If you've lifted your Jeep or are thinking about it, your factory brake lines are probably too short. This isn't a minor inconvenience—stretched or strained brake lines can affect how your pedal feels and compromise your safety. The Rough Country stainless steel brake lines model 89715 are engineered specifically for lifted Jeeps, but knowing whether they're right for your vehicle requires understanding a few key things about your Jeep's generation and lift height.

Understanding Your Jeep's Generation: YJ, TJ, and XJ Models

Jeep Wranglers went through several generations between 1987 and 2006, and each has slightly different brake line routing and connection points. The YJ generation ran from 1987 to 1995, the TJ from 1997 to 2006, and the XJ (Cherokee) used a different platform altogether. The Rough Country stainless brake lines 89715 are designed to fit all three, but the critical detail is your lift height.

These lines come with 25-inch front and rear lengths, which is the standard extension for Jeeps with 4 to 6 inches of lift. If your lift is smaller than 4 inches, you might have excess line length that creates unnecessary loops. If your lift exceeds 6 inches, these lines may still be too short, and you'd need to confirm compatibility or look for a different solution. Check your vehicle's documentation or suspension paperwork to confirm your exact lift amount before ordering.

Why Stainless Steel and Braided Design Matter

Standard rubber brake lines deteriorate over time and aren't designed to handle the abuse of off-road driving. Sharp rocks, branches, and mud can puncture or abrade them. The braided stainless steel exterior on these Rough Country lines acts as armor, protecting the inner hose from damage while resisting corrosion from road salt and moisture.

Inside, the Teflon core is designed to withstand pressures up to 4,000 PSI, which covers both everyday driving and extreme off-road conditions where brake systems experience stress from rough terrain. This internal material also prevents the line itself from expanding under pressure, which keeps your brake pedal feel firm and consistent instead of spongy or unpredictable.

DOT Approval and What It Means

These lines carry DOT approval, which means they meet Department of Transportation safety standards for brake fluid containment and pressure ratings. This matters because brake lines are a safety-critical component. DOT-approved lines have been tested for durability and reliability. If your region requires inspection or you simply want peace of mind, this certification is important.

Installation and Connection Points

The hollow fasteners at each end of the Rough Country stainless brake lines 89715 are where the lines connect to your brake calipers and master cylinder. These need to be tight and secure—a loose connection will leak brake fluid and leave you without brakes. During installation, use the correct wrench size and apply appropriate torque without over-tightening, which can strip the fitting. If you're unfamiliar with brake work, this is one job worth having a professional handle, as mistakes can be dangerous.

Maintenance and Longevity

Stainless steel brake lines last significantly longer than rubber ones, often the life of the vehicle with proper care. Inspect them periodically for damage to the braided exterior or any signs of leaking at the fittings. Keep them clean of caked mud and debris, which can trap moisture. If you brake heavily or frequently drive in mud, checking them every few months is reasonable. Brake fluid itself should be flushed according to your Jeep manufacturer's recommendations, regardless of line type.

Upgrading your brake system when you lift your vehicle isn't optional—it's necessary for safety and performance. The Rough Country stainless brake lines 89715 address this need with durable construction and proper engineering for your specific Jeep model and lift range.
