Upgrade your cooling system with the PPE Silicone Lower & Upper Radiator Hose Kit for 2017-2019 GM 6.6L Duramax L5P.

Factory coolant hose T fittings are known to crack and leak over time, but PPE’s kit eliminates that problem with TIG welded, polished 304 stainless steel T fittings, no more worrying about failures at the junctions. Designed for both stock and high performance Duramax trucks, these hoses feature 4-ply heat-resistant internal fibers for superior strength under high pressure and temperature conditions. The 5mm thick silicone is twice as thick as factory hoses, ensuring long lasting durability. Plus, the quick-connect/disconnect end is precision machined from billet aluminum and 304 stainless steel for a reliable, leak free fit. Stainless steel clamps provide a secure seal, outperforming factory options.

This direct bolt-on upgrade requires no cutting or modifications, giving you OEM fitment with better than OEM performance, so you can keep your truck running cool and strong.
