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.

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.

My favorite low socks ever
Fit Type: Classic Fit, Color: Gray Assorted, Size: Large
Under armour adult essential Lite no-show socks are 96% polyester and 4% spandex footwear of imported origin. The polyester content of the socks enables them to hold their shape in a better manner along with having a non-absorbent nature. Additionally, it enables the socks to retain the colour in a better manner. Spandex improves their fit along with helping them last for longer time. The flat fit construction of UA Men's Essential Lite is so designed to conform to foot for superior touch and feel. The material wicks engineered within the fabric dry sweat quickly and keep the feet fresh. The embedded arch support further keeps you going by reducing foot fatigue. The set comes with 6 pairs of socks with pull on closure for the perfect fit. Ultrathin lightweight construction of the socks adds to user comfort by allowing users to conduct physical activity and work out while wearing it. Elastic strength of the socks prevents them from slipping down irrespective of the shoes they are worn with. The socks come in 8-12 men shoe size and 9-12 women shoe size. They can be machine washed and are extremely durable while being cost effective. I ordered the socks based on their colour and design symmetry. So far my socks have been through multiple washes and still look new and user ready. I wear them daily because of their amazing fit and plan to buy more as Christmas gifts.
