California's Prop 65 Warning: Click Here for Detail

International Buyer: Shipping charge does not included Custom Charge and Brokerage Fee (Detail)

As LS engines are becoming increasingly popular to swap, we saw an opportunity to develop a product catered to LS powered enthusiasts. Whether your car or truck came with an LSX, or you are swapping one in, the HPS LS Heater Bypass Loop is a necessity for those who plan to bypass the cabin heater. This easy to install loop eliminates concerns about air pockets that can develop when capping off your heater lines.

This is the lowest profile heater loop on the market, measuring in at only 3 inches tall. We reinforced this hose with 4 layers of polyester between each layer of premium quality silicone. The HPS LS Heater Bypass Loop will install on any LS family engine (LS1, LT1, LQ9, etc) with 5/8"" and 3/4"" heater supply and return ports. Embossed stainless steel hose clamps are included for easy installation.

Key Features
- Loops the heater supply and return ports on your LSX water pump.
- Reduce curb weight by allowing safe removal of the heater core.
- CAD modeled designed using 3D scanning technology.
- This is the lowest profile heater loop on the market, measuring in at only 3 inches tall.
- Includes 100% stainless steel non-perforated embossed hose clamps for easy installation, which do not cut through the silicone hoses.
- Prevent and fix the coolant leaking and engine overheating problem caused by cracked, damaged or collapsed OEM rubber heater coolant hoses.
- Race proven design with long lasting quality and engineered for extremely high temperature service (Max. 350F) and prolonged exposure to under-hood and coolant heat.
