The 600-1-HSP is best known as the HSP Diesel Hot Side Tube for the 2017-2019 L5P Duramax Equipped Chevrolet and GMC trucks.


Changing the Hot Side Tube on the L5P Duramax is something that every single truck on the road can benefit from. With no tuning needed and basic knowledge to change it this kit is something that everyone needs.


Why would you need the HSP Diesel Hot Side Tube for the 2017-2019 L5P Trucks?

The factory hot side on the L5P Duramax trucks is something that just doesn’t work like it should and just doesn’t hold up to the demands of the even stock application. All too often that hot side pipe fails and causes you to be down on the side of the road or attempting to limp yourself home.


What does the HSP Diesel Hot Side Tube do differently?

The HSP Diesel Hot Side Tube for the 2017-2019 L5P is made from aluminized steel. This gave us a lot more strength but also allowed us to make mandrel bends. The mandrel bends give us the strongest and best shapes to our bends to allow for the best flow and least amount of turbulence. The HSP Diesel Hot Side Tube for the 2017-2019 L5P is the easiest to install hot side tube on the market today and requires no tuning to install. Included in this kit is 5-ply, high-strength, silicone boots to replace the weak and prone-to-fail factory boots. This means you will be on the road longer and with a more reliable platform.


What comes with the HSP Diesel Hot Side Tube?

  • (1) 3 inch 43 Degree Boot
  • (3) 3 inch T-Bolt Clamp
  • (1) 2.75 inch – 3 inch Reducer Boot
  • (1) 2.75 inch T-Bolt Clamp


Special note

This only Fits the 2017-2019 L5P engines even though the Vin code is the same. This is due to small changes that were made in the engine bay. Please be sure you are ordering for the correct year truck.


What Does the HSP Upper Coolant Tube fit?

  • L5P: 17-19 VIN Code Y


How do people know the VIN code?

Engine code is dictated by the 8th character of the VIN number. The 10th character is the year of the truck.
