DeatschWerks High-Flow Fuel Rails – 2005-2023 Dodge & Chrysler HEMI V8 (5.7L / 6.1L / 6.4L)
The DeatschWerks High-Flow Fuel Rails are a premium billet aluminum upgrade for the factory fuel rails on 2005-2023 Dodge and Chrysler HEMI V8 engines (5.7L, 6.1L, and 6.4L). These rails feature larger internal passages and precision-machined injector seats for significantly improved fuel flow and even distribution to all eight injectors.
Designed as a direct bolt-on replacement, they retain factory mounting points while providing better injector clamping and sealing at elevated fuel pressures. The durable black anodized finish gives a clean, professional appearance under the hood.
Perfect for naturally aspirated, supercharged, or turbocharged HEMI builds pushing well beyond stock power levels, these fuel rails ensure consistent fuel delivery and reliable performance under high-demand conditions.
Key Features
- High-Flow Design – Larger internal passages for superior fuel delivery and high-horsepower support
- Billet Aluminum Construction – Lightweight, strong, and precision-machined for perfect fitment
- Black Anodized Finish – Attractive, corrosion-resistant appearance
- Direct Bolt-On – Retains factory mounting locations and injector spacing
