Mishimoto Red Silicone Radiator Hose Kit for 2012–2021 Jeep Grand Cherokee SRT8 6.4L HEMI
The Mishimoto MMHOSE-WK2-12RD red silicone radiator hose kit replaces the brittle factory rubber hoses on 2012–2021 Jeep Grand Cherokee SRT8 with the 6.4L HEMI, featuring 4-ply reinforced silicone construction that withstands 70+ PSI and temperatures up to 330°F for lifelong durability under extreme heat, pressure, and off-road abuse. This complete kit includes upper hose, lower hose, and all stainless T-bolt clamps for a perfect leak-free fit.
Engineered with smooth internal walls for unrestricted coolant flow and vibrant red finish that adds aggressive under-hood style, these hoses eliminate the common factory hose failures that cause overheating and coolant leaks on high-mileage or tuned SRT8s. Direct bolt-on installation reuses factory quick-connect fittings and includes Mishimoto’s lifetime warranty.
For SRT8 owners demanding maximum cooling system reliability with show-quality appearance, the Mishimoto silicone radiator hose kit is the ultimate upgrade trusted on thousands of 6.4L Grand Cherokees worldwide.
