is the performance division of Leyland Hose & Silicone, bringing OEM-level engineering, manufacturing expertise, and proven reliability into the world of performance and motorsport.
Designed for enthusiasts, tuners and professional builds, our silicone hoses deliver performance under pressure, without compromise.
We take that same engineering expertise and apply it to performance applications, delivering hoses that are designed to handle extreme temperatures and pressures, manufactured using high-quality materials and built to perform consistently in demanding environments
Trusted by vehicle manufacturers and aftermarket specialists, our hoses are engineered to deliver reliability, durability and performance where it matters most.
We understand the frustration in that, too often, the choice is: high-quality hoses with long lead times, or fast delivery with compromised quality. At Extreme14, we’ve built our range to eliminate that trade-off offering high-performance hoses, available from stock, with fast delivery, with no compromise on quality, or waiting months for parts, ust reliable products when you need them.
Motorsport isn’t just something we supply, it’s something we’re part of, our team actively participates in motorsport events, drift days and automotive shows
This means we don’t just understand the theory, we understand real-world performance demands and we design products that perform not just on paper, but on the road and on the track.
