HSP Diesel Hot Side Tube for 2011-2016 Chevrolet and GMC LML Duramax

HSP Hot Side Tube for 2011-2016 Chevrolet / GMC Duramax LML

Part Number: 500-HSP

The 500-HSP, best known as the HSP Hot Side Tube for the 2011-2016 LML Duramax-equipped Chevrolet and GMC trucks, addresses a common failure point and provides a significant upgrade in performance and durability.

Why Choose the HSP Hot Side Tube?

The factory hot side pipe is a notorious weak link on Duramax trucks. When it fails, it can cause serious boost leaks, resulting in power loss and poor drivability, especially under load or while towing. Replacing it with a high-performance alternative is essential to avoid these issues.

What Makes the HSP Hot Side Tube Different?

The HSP Hot Side Tube improves airflow by up to 40% over the factory setup. Constructed from 3" mandrel-bent tubing, it minimizes restriction and turbulence. Unlike the OEM design, HSPs tube uses sweeping, high-flow bends and a straight-through connection to the intercooler. This eliminates the need for the problematic two-piece silicone boot, a known source of boost leaks.
