Built To Handle Boost When The Pressure Is On

When you start turning up the power on your 2011-2016 Duramax LML, the last thing you want is a weak hose becoming the failure point. PPE designed this silicone hose for trucks that see serious boost, whether that is at the drag strip, on the sled pull track, or hauling heavy up a long grade. With five plies of polyester reinforced fibers, it has the strength to hold steady when pressure spikes fast and hard. Additionally, the fluorocarbon lining adds extra protection against fuel and oil contamination, which helps maintain long term durability in real world conditions. This is the kind of upgrade that gives you confidence when you lean into the throttle and expect everything to hold together. It performs just as well on a daily driven truck as it does in competition, making it a smart choice for builds that do a little bit of everything. If you are investing in performance parts, upgrading your hoses is a simple way to protect that investment.

Multi Layer Reinforced Silicone Engineered For Extreme Conditions

The PPE 115900900 silicone hose is constructed with a 5 ply polyester reinforced design that provides exceptional strength under sustained boost pressure. Its thick 6mm wall helps resist expansion and reduces the likelihood of blowouts compared to factory rubber hoses. The internal fluorocarbon lining improves lubricity while offering increased resistance to fuel, oil, and chemical exposure. Furthermore, the silicone compound is rated to handle temperatures from -76 degrees to 437 degrees Fahrenheit, making it suitable for harsh climates and high heat engine bays. UV and ozone resistance also help preserve the material over time, especially in trucks that see regular outdoor use. This hose is designed specifically for 2011-2016 GM Silverado and Sierra 2500HD and 3500HD 6.6L Duramax LML applications. Due to the thicker wall construction, hose clamps should be sized one half inch larger than the hose inner diameter to ensure proper fit and sealing.
