Heavy Duty Silicone Coolant Hose Kit Compatible With 2015-2018 Dodge Ram Cummins 2500 3500 6.7L Diesel

The 5th gen Cummins is a proven platform. Don't let aging factory rubber be the weak link in your cooling system.

Built specifically for the 2015–2018 Dodge Ram 2500 and 3500 with the 6.7L Cummins diesel, this complete silicone coolant hose kit is a direct, no-modification replacement. These trucks are hitting the mileage window where OEM rubber starts to show its age — stiffening, surface-cracking, and losing its seal under the sustained heat and pressure of a diesel engine. Our 4-ply reinforced silicone construction is built to outlast it by a wide margin.

WHY SILICONE OVER RUBBER

Temperature resistant — Handles sustained heat and pressure that cause factory rubber to soften, crack, and fail.
4-ply reinforced wall — Multiple reinforcement layers prevent collapse under hard towing, hauling, and high-RPM demand.
Maintains elasticity — Silicone stays flexible in cold starts — no cracking, no stiff spots, no pinhole leaks.
Outlasts OEM — Designed as a long-term upgrade, not a repair. Install once and move on.

WHAT'S INCLUDED

✓ Complete upper and lower radiator hose set
✓ All stainless steel clamps and hardware
✓ Matte black finish — clean, stealthy look under the hood
