I have these listed on Ebay for $11.98 each. TSC member's will receive a 10% discount. It's a formed bypass heater hose for LS1, LS2, LS3, L92, L99, LS6, LS7, LSA, L76 with stock water pumps. If you bend a straight section of heater hose it will kink and restrict the flow of coolant. The hose ends 5/8" and 3/4" are an exact fit. As you can see in the picture it fits perfectly. You can use the stock clamps.
