This Xtreme‑Duty hose kit is built for the trucks that work for a living. The factory lines on the Duramax trucks are known for getting tired, seeping, or ballooning under heat and pressure — so we put together a heavy‑duty set that bolts in clean and holds up to real use.

Each hose is made to match the OE routing and lengths, but upgraded with tougher materials and PSC‑spec fittings. Hydro‑boost to pump, hydro‑boost to gear, and cooler return — every high‑pressure and return line you need is right here in one kit. These install just like the originals and give you the durability the factory pieces wish they had.
