Engineered specifically for 2011 through 2016 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke turbo diesel engine, the No Limit Fabrication Stainless Upper Coolant Hose Kit in Raw Finish (67UCHKR1116) replaces the bulky, fatigue-prone factory rubber upper radiator hose. Operating under continuous thermal cycles, heavy towing strain, and high coolant pressures, the stock rubber hose softens and expands over time, leading to wall degradation and unexpected roadside burst failures.

The No Limit Fabrication system replaces the factory molded hose with a rigid, mandrel-bent 304 stainless steel hard pipe. Paired with heavy-duty silicone boots and stainless steel clamps, this upgrade eliminates wall ballooning, withstands extreme under-hood operating temperatures, and provides reliable coolant flow between the thermostat housing and primary radiator inlet. The raw stainless finish provides a clean, purposeful mechanical aesthetic under the hood that can be run bare or custom-coated to match custom intake and intercooler piping.

Key Features & Benefits

• Mandrel-Bent 304 Stainless Steel Construction: Eliminates rubber wall expansion, heat softening, and blowout risks under heavy towing and high engine boost levels.
• Heavy-Duty Reinforced Silicone Couplers: Multi-ply silicone boots isolate chassis flex and engine torque vibration while sealing reliably under high cooling system pressure.
• Prevents Sudden Roadside Coolant Loss: Upgrades the most failure-prone primary hose in the cooling circuit to permanent stainless steel hardware.
• Direct Bolt-On Replacement: Precision-formed geometry installs cleanly in place of the factory upper hose with zero cutting or bracket modifications.
• Customizable Raw Finish: Supplied in a clean raw stainless finish ready for immediate drop-in use or custom polishing, painting, or powder coating.

• Installation Tip: Clean the radiator connection neck and thermostat outlet thoroughly to remove any old rubber residue or corrosion. Slide the silicone boots on with a light coating of soapy water to ease alignment, and torque the clamps evenly past the pipe bead roll to prevent blow-offs under pressure.
