LS SERIES STEAM BLEED KIT

🔧 Product Description

The Fittings247 LS Series Steam Bleed Kit is a must-have upgrade for LS engines, designed to improve cooling efficiency by allowing trapped air and steam to escape from the cylinder heads. By incorporating the rear head steam ports, this kit helps reduce hotspots and temperature imbalances that can lead to engine damage or failure—making it essential for any performance LS build.

Each kit is fully assembled and pressure tested in-house, ensuring a reliable, leak-free installation. Available with your choice of push lock fitting or braided line fitting, this kit gives you the flexibility to route the bleed line back to the radiator or another suitable location, or simply cap it off if not required.
