Rough Country Jeep Wrangler JK Stainless Brake Lines for 4–6" Lift — 24" Front & 22.5" Rear, Braided PTFE

Rough Country stainless steel brake lines provide longer, tougher brake hose replacements designed specifically for lifted Jeep Wrangler JK models (2007–2018) with 4–6" lifts — front 24" and rear 22.5" included.

When you raise a Jeep, factory rubber brake hoses can become overstretched, worn, or vulnerable to debris. These Rough Country kits replace aging or undersized lines with DOT-approved stainless steel braided hoses sized for a 4–6" lift, restoring proper routing and adding abrasion resistance for off-road use. The kit includes a 24" front hose and a 22.5" rear hose engineered to fit the JK’s brake fittings and mounting points.

How do these stainless steel lines improve durability compared to stock hoses?

The braided stainless steel outer jacket resists cuts, rubbing, and punctures that commonly damage rubber hoses in off-road conditions. Inside, a PTFE (Teflon) liner minimizes expansion under pressure, keeping pedal feel consistent and helping maintain braking performance over time.

• Braided stainless exterior stops rocks and branches from penetrating.
• PTFE inner liner reduces hose expansion under braking force.
• Stainless fittings and quality crimps provide a reliable, leak-resistant connection.
• DOT-approved materials meet regulatory standards for on-road use.

Will these lines fit my Jeep Wrangler JK with a 4–6" lift?

Yes — the kit is manufactured for JK models from 2007–2018 that have been lifted between 4 and 6 inches. The front line measures 24 inches and the rear line measures 22.5 inches to accommodate the greater travel and altered geometry of lifted suspension setups.

• Front hose length: 24"; rear hose length: 22.5".
• Designed for 2007–2018 Jeep Wrangler JK models.
• Made to fit common 4–6" lift configurations without extensive modification.
• Includes necessary stainless fittings for OEM-style attachment points.

What installation details should I know before buying?

Installation typically involves removing the factory hose, attaching the new stainless line to existing hardline and caliper fittings, and securing it along the original brackets. While a competent home mechanic can complete the swap with standard tools, proper torque and a brake bleed afterward are essential to ensure a safe, leak-free system.

• Swap in place of existing hose using supplied stainless fittings.
• Follow torque specs for brake fittings to prevent leaks.
• Bleed the brake system thoroughly after installation.
• Check hose routing and retention points under full articulation.

What kind of warranty or support does Rough Country provide?

These brake lines come backed by Rough Country’s Lifetime Replacement policy, giving you long-term coverage against defects. If the hose fails due to manufacturing issues, Rough Country’s support replaces the part under their stated program — always check the company policy details for terms and exclusions.

• Lifetime Replacement coverage from Rough Country.
• Contact Rough Country customer service for claims or fitment questions.
• Keep proof of purchase and product details when requesting support.

Who is this for? Off-roaders and daily drivers who have lifted their Jeep Wrangler JK 4–6 inches and want a durable, DOT-approved brake line upgrade will benefit from this Rough Country kit. It’s a practical choice for anyone replacing worn factory hoses or building a lift with confidence in hose routing, abrasion resistance, and long-term reliability.
