Introducing the HSP Diesel Hot Side Tube

The 600-1-HSP is your go-to solution for the HSP Diesel Hot Side Tube, designed specifically for the 2017-2019 L5P Duramax-equipped Chevrolet and GMC trucks.

Why Upgrade to the HSP Diesel Hot Side Tube?

Upgrading the Hot Side Tube on your L5P Duramax can make a world of difference. This is an upgrade that every truck can benefit from. The best part? You don’t need any tuning, and with just a bit of basic knowledge, you can install it yourself. It’s a must-have for every truck owner!

What Makes the HSP Diesel Hot Side Tube Stand Out?

The factory hot side on L5P Duramax trucks often falls short, struggling to meet the demands of even stock applications. Many drivers experience failures that leave them stranded or limping home. That’s where the HSP Diesel Hot Side Tube comes in. Crafted from durable aluminized steel, this tube offers enhanced strength and features mandrel bends, which are designed for optimal flow and minimal turbulence. Plus, it’s the easiest hot side tube to install on the market—no tuning required! The kit also includes 5-ply, high-strength silicone boots to replace the factory boots that are prone to failure. With this upgrade, you’ll enjoy more time on the road and a more reliable driving experience.
