Why Upgrade the L5P Hot Side Tube?

The factory hot side pipe on L5P trucks is known for early failures—even under stock power levels. A failed hot side pipe can leave you stranded or force you to limp the truck home. HSPs Hot Side Tube addresses these issues with superior materials and construction.

What Makes the HSP Hot Side Tube Different?

Constructed from aluminized steel and mandrel-bent for optimal flow, the HSP Hot Side Tube offers greater strength and reduced turbulence. It comes with 5-ply, high-strength silicone boots and durable T-bolt clamps, eliminating the factorys weak connections and ensuring long-term reliability. No tuning is needed, and installation is simple—even for beginner-level installers.
