Description
The Mishimoto MMHOSE-WR6-12RD is a red silicone radiator hose kit built as a specific-fit replacement for the factory rubber hoses on Jeep Wrangler models. This Cooling-system upgrade pairs upper and lower silicone hoses with four worm-gear clamps, swapping out degradation-prone rubber for a five-layer silicone construction reinforced with heat-resistant embedded fibers. It’s backed by the Mishimoto Lifetime Warranty, whether your Wrangler spends its time on the street, the trail, or crawling over rocks.
Rubber radiator hoses break down over time from constant heat cycling and pressure, eventually cracking, collapsing, or failing when you least expect it. Mishimoto’s silicone hose kit carries a maximum temperature rating of 330°F, giving your Jeep’s Cooling system added heat and pressure tolerance compared to the factory rubber it replaces. As a Performance-grade, specific-fit hose kit, it installs in place of the stock upper and lower radiator hoses, and the included worm-gear clamps simplify the installation process. If you’ve been searching for a durable Jeep Wrangler radiator hose kit, this Mishimoto silicone hose kit is designed to hold up to both daily driving and off-road abuse.
