89715 Stainless Extended Brake Lines for 4-6in Lift - Durable Upgrade

Our review of the 89715 Stainless Brake Lines concludes they are a clear upgrade for Jeep owners running 4-6in lifts who need longer, more durable brake lines. Built from braided stainless steel, these lines replace part number 89715 and are intended for drivers of 1987-2006 4WD Jeep Wrangler models and 1984-2001 Jeep Cherokee XJ who want firmer, more responsive braking and better protection from off-road debris. The review finds the lines deliver improved pedal feel and corrosion resistance while allowing minor end modifications when different calipers require it.

Key Features

• Stainless construction: Long-lasting stainless steel resists corrosion for extended service life in wet or salty conditions.
• Braided exterior: The braided stainless steel cover protects the hose from rocks, mud and off-road impacts that can damage stock lines.
• Extended length: Designed for 4-6in lifts so the lines provide proper slack and reduce strain on fittings during suspension travel.
• Improved braking feel: The internal design limits expansion under pressure, producing firmer and more responsive pedal feedback.
• Replace part number 89715: Direct replacement line set that matches factory routing for compatible Jeep models.
• Modifiable ends: If your vehicle uses different calipers, the line ends can be modified to suit application requirements.

Who It's For

This kit is best for Jeep owners who run a 4-6in lift on Wrangler TJ, YJ or Cherokee XJ models and need to replace stretched or aging brake lines with a corrosion-resistant, longer alternative. Trail riders and daily drivers who encounter mud, gravel and salt will benefit from the braided protection and firmer pedal feel.

It is not aimed at owners who have stock ride height with no clearance issues or those who require a pre-flared custom end for an unusual caliper without modification-they should plan for a professional end modification or a custom hose if exact fittings are critical.

Pros & Cons
