Racewill Brake Line 89717 Stainless Steel Extended Brake Hoses for 1999–2004 Ford Super Duty F250/F350 4"–8" Lift — Braided, Leak-

When you raise a Super Duty 4WD for off-road capability or towing clearance, stock brake hoses can become too short or vulnerable. These extended hoses replace OE part number 89717 and give the extra length and durability needed for 4"–8" suspension lifts while maintaining a secure, leak-free connection to your vehicle's braking system.

How do these extended brake lines improve braking reliability on lifted trucks?

The Racewill 89717 lines use a multi-layer design with a stainless steel braided outer cover that prevents stretching and resists abrasion from rocks and debris. Internally, the hose construction limits expansion under hydraulic pressure, producing firmer pedal feel and consistent brake response even under heavy loads.

• Prevents hose swelling for steady brake pressure
• Stainless braid shields against punctures and cuts
• Durable fittings reduce chance of leaks at connections

Will these lines fit my 1999–2004 Ford Super Duty with a 4"–8" lift?

Yes — these lines are built as direct replacements for OE part number 89717 and are dimensioned specifically for Ford F250/F350 4WD models lifted between 4" and 8". They retain factory-style end fittings for simple installation without custom adapters in most cases.

• Compatible with 1999–2004 Ford Super Duty F250/F350 4WD
• Designed for 4"–8" suspension lifts to prevent overstretching
• Factory-matching connectors for plug-and-play replacement

What materials and features protect the lines from harsh environments?

The exterior braided stainless steel layer resists corrosion from road salts, oils, and chemicals while adding a protective shield against off-road impacts. Precision-machined connectors provide smooth, leak-resistant joints, and the overall assembly is selected to tolerate greasy, muddy, and abrasive conditions common to heavy-duty use.

• Stainless steel braid for anti-corrosion and abrasion resistance
• Inner core engineered to maintain rigidity under pressure
• Precision fittings reduce leak risk and ensure secure seating

How hard is installation and what should I check during fitment?

Installation is straightforward for anyone comfortable with brake line replacement: remove the old OE 89717 line, swap in the Racewill extended line, and torque the fittings to spec. After installation, bleed the brakes, inspect for leaks, and check for rubbing across the suspension travel range.

• Replace OE part 89717 with Racewill extended line
• Bleed system and torque fittings to manufacturer specs
• Verify clearances through full steering and suspension travel

Who is this for: These Racewill stainless steel extended brake lines are aimed at owners of 1999–2004 Ford Super Duty F250 and F350 4WD trucks who have installed a 4"–8" suspension lift or plan to run heavier loads or frequent off-road use. If you want a direct-fit replacement that improves pedal feel, increases resistance to corrosion and abrasion, and preserves safe brake operation after lifting your truck, this kit is engineered to meet those needs.
