Racewill Extended Brake Lines for 4"-6" Lift Jeeps — Stainless-Braid Front & Rear, Direct-Fit

Racewill 89715 stainless steel extended brake lines are a direct-fit upgrade that replaces factory hoses to deliver more durable, corrosion-resistant braking lines for lifted Jeep TJ, YJ, and Cherokee XJ models.

If you run a 4"–6" suspension lift on classic Jeep platforms, stock rubber brake hoses can become overstretched or damaged during full suspension travel. These Racewill 89715 lines (front pair 89702 and rear 89703) use stainless-steel braid over a pressure-stable inner hose to resist abrasion, prevent ballooning under pressure, and stand up to off-road impacts. They’re built as a replacement assembly to match the routing needs of lifted 1997–2006 Jeep Wrangler TJ, 2004–2006 TJ Unlimited, 1987–1995 Wrangler YJ, and 1984–2001 Jeep Cherokee XJ models.

How do these extended brake lines improve braking feel and reliability?

The stainless construction reduces hose expansion compared with stock rubber lines, giving a firmer pedal and more consistent response under repeated use. The braided outer layer protects against rocks, branches, and debris encountered off-road, helping avoid leaks and punctures.

• Stainless braid shields against abrasion and corrosion.
• Inner hose resists pressure expansion for firmer braking.
• Longer length accommodates 4"–6" lift geometry without stretching.

Will these lines fit my Jeep and require modifications?

Racewill designed the 89715 assembly as a direct replacement for specified Jeep years and drivetrains; however, variations in aftermarket calipers or custom setups may need minor end fittings adjustments. The kit replaces OEM part number 89715 and includes both front and rear lines labeled 89702 and 89703 for correct placement.

• Compatible with 1997–2006 4WD Jeep Wrangler TJ and 2004–2006 TJ Unlimited.
• Also fits 1987–1995 Wrangler YJ and 1984–2001 Cherokee XJ (2WD/4WD).
• End fittings can be modified if your caliper hardware differs from stock.

How are these brake lines constructed and protected?

The lines combine a high-pressure inner tube with a stainless-steel braided exterior to resist swelling and environmental damage. That layered build preserves brake fluid integrity and minimizes the chance of hose failure during demanding use.

• Stainless steel braid for impact and abrasion resistance.
• Corrosion-resistant materials for long service life in wet and salty conditions.
• Designed to prevent internal expansion under hydraulic pressure.

How difficult is installation and what should I prepare?

Installation follows standard brake-line replacement procedures—bleed the system after swapping lines—and most mechanically inclined owners can complete the job with common tools. If your vehicle uses non-stock calipers, you may need to alter the hose ends or use adapter fittings.

• Requires brake bleeding after installation for safe operation.
• Basic hand tools, flare wrench set, and brake fluid recommended.
• Minor end fitting modification possible for some aftermarket calipers.

Who is this for: The Racewill 89715 extended brake line kit is aimed at off-road enthusiasts and Jeep owners who have lifted their TJ, YJ, or XJ between 4" and 6" and want a durable, pressure-stable replacement for factory hoses. It’s also suitable for anyone replacing aged rubber lines or seeking improved abrasion resistance and more consistent pedal feel under heavy use. If you need a direct-fit upgrade built for off-road conditions and longer service life, this kit covers both front and rear needs for the listed Jeep models.
