Drag racing and sled pulling places huge stress on your trucks silicone hoses in a very short period of time. >PPEs hoses were designed to handle the rigors of increased pressure during racing and competition. They are equally proficient at daily driving and towing heavy loads.

Each PPE Performance Silicone Hose is strengthened with 5 plies of polyester reinforced fibers making them very tough. The Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures that they can withstand constant boost pressures from -76 degrees all the way to plus 437 degrees Fahrenheit. In short, PPE Performance Silicone Hoses will not blow out like a stock hose will.
