Manufacturer Description

Replace your leaking or corroded heater tubes with our upgraded stainless steel tubes and high temperature silicone hose kit from Fleece Performance. This kit contains everything you need to replace your heater lines from the block to the firewall.

This kit is designed as a direct replacement for all trucks originally equipped with air conditioning.

Application Notes:
This kit is intended for use with trucks originally equipped with air-conditioning. If your truck is not equipped with air conditioning, you will need to supply your own 5/8 inch ID hose to run from the firewall ports to the stainless steel heater lines.
The silicone heater hose (tube to firewall) may require trimming for certain applications or to accommodate modifications made previously to the engine.
If your truck is equipped with an aftermarket exhaust manifold, the rear heater line standoff will not be utilized and an additional mounting bracket is provided.

We love this stuff
Color: A, Color: A
My baby had an infection in his hair that he got once he started daycare. We tried everything to kill the fungus. It got so bad I had to take him to the doctor and they finally gave him some antibiotics and medicated shampoo. His head was so sore and tinder he didn’t want anyone to touch his head. So imagine trying to wash his hair everyday. The shampoo killed the fugus and took his hair out where it was. I purchased this product. IT REALLY WORKS!!!!!! We’ve been using it a few weeks and we definitely see a difference. P.S I went and purchased the whole set

I like it
Color: A
I'm unsure how it affects hair growth since I've only had one jar. It does leave hair moisturizedand soft. It has a really nice scent.

Love this product!
Color: A
This really keeps the hair moisturized. Don’t use it too much because it causes build up. You can use as a conditioning treatment and wash it out or you can use it as a moisturizer.
