Product Details

The Mishimoto MMHOSE-GM-17U is a high-performance silicone upper radiator hose designed as a direct replacement for 1978-1986 GM C/K pickup trucks equipped with 305ci or 350ci small block engines. This upgrade replaces the factory rubber hose with a superior silicone construction that dramatically improves durability and heat resistance.

Key Features:

  • Five-layer silicone construction with heat-resistant embedded fibers for maximum durability
  • Significantly improved heat and pressure tolerance compared to OEM rubber hoses
  • Direct-fit design for hassle-free installation on 1978-1986 GM C/K trucks with 305ci/350ci engines
  • Includes premium stainless steel worm-gear clamps for secure, leak-free connections
  • Available in black for a clean, stealthy under-hood appearance
  • Resistant to coolant degradation, UV exposure, and extreme temperature cycling

Mishimoto silicone radiator hoses are engineered to outlast and outperform factory rubber hoses, making them an ideal upgrade for daily drivers, work trucks, and performance applications. The multi-layer silicone construction maintains flexibility across a wide temperature range while providing superior resistance to heat-induced cracking and deterioration that commonly affects OEM rubber hoses over time.
