Stop Trusting Old Hoses With Big Power On The Line

If you're still running stock boost hoses on your LML Duramax, you're gambling with performance every time you get on the throttle. The PPE Silicone Hose & Clamp Kit is built for truck owners who push their rigs hard, whether it’s towing heavy, racing on weekends, or hauling through mountain grades. This kit gives you peace of mind by replacing weak factory rubber with premium 5-ply silicone reinforced hoses and heavy-duty clamps that hold tight under serious pressure. It’s the kind of upgrade you make once and never have to think about again. The included fluorocarbon lining helps resist wear from oil and fuel exposure while keeping internal friction low, which means better durability and flow consistency over time. Whether you're pulling a trailer or launching off the line, you need parts that won’t fold under stress. This kit delivers the strength and reliability that every high-performance Duramax build deserves.

Engineered To Withstand The Heat And The Boost

The PPE 115911114 Silicone Hose & Clamp Kit is designed specifically for 2011–2016 Duramax LML trucks and built to thrive in harsh, high-pressure environments. Each hose features a rugged 5-ply polyester construction that helps maintain structural integrity even under extreme boost levels. With operating temperatures ranging from -76°F to 437°F, these hoses remain flexible in the cold and stable in the heat, making them ideal for both winter startups and full-throttle towing sessions. A fluorocarbon inner lining provides excellent resistance to fuel, oil, and chemical exposure, which helps prevent breakdown or swelling from long-term use. The outer silicone layer is UV and ozone resistant, protecting against dry rot or surface cracking under the hood. PPE’s hose walls measure a thick 6mm, which is why oversized clamps are included in the kit to ensure a tight, reliable seal. This isn’t just a replacement, it’s a serious upgrade for any LML looking to run stronger and cooler under pressure.
