The kit will also fit 99-07 SUV applications with minor changes to the heater fittings, instructions included. This is the only 5 piece kit available for these trucks, and includes the only expansion tank/heater hose on the market that utilizes a one-piece design on the y-branch to replace the problematic OEM plastic branch fitting. Kit Includes: Upper Radiator Hose Lower Radiator Hose One Piece Y-Branched Heater/Expansion Tank Hose Secondary Heater Hose Expansion Tank-to-Radiator Hose Optional 11 Lined Hose Clamps Optional Metal Heater Core Quick Connect Fittings NOTE: Optional metal heater core fittings are NOT compatible with vehicle applications which have rear heat (full-size SUV models only). Why Choose Silicone? There are several advantages to silicone hoses beyond just their cosmetic aspect. Primarily the higher resilience to high underhood heat (such as in a turbocharged application, or even just the additional heat from long tube headers). They do not harden up or dry rot from excessive heat, these have an operational heat range of -40 to 475 degrees. These hoses will maintain their pliability and flexibility throughout their entire lifespan. Furthermore, the multi-ply silicone can handle much higher pressures than traditional rubber, these hoses are burst tested to 250psi and can sustain operational pressures up to 72.5psi (about 4.5 times the standard cooling system pressure). Silicone is much more impervious to oil based contaminants, and will not break down like rubber when exposed to oil or other lubricants. When compared to rubber hoses, the service life of silicone is unparalleled, these would likely be the last set of hoses you would ever need to purchase for your truck.
