Product Description

The DeatschWerks 7-206 fuel rails are precision-engineered performance upgrades for LS Gen 3 and Gen 4 trucks and SUVs produced from 1999 to 2017, including Silverado, Sierra, Avalanche, Escalade, and Yukon models. CNC-machined from billet T6061 aluminum and hard-anodized black, they offer durable construction and optimized flow paths. The oversized -8 AN ORB ports and 3/8" NPT bottom ports allow seamless integration of high-flow injectors and fuel accessories like dampers.

These rails are versatile, supporting both return and returnless fuel systems. The integrated CNC brackets maintain perfect injector alignment, essential for consistent spray patterns and performance. A Schrader valve is included to facilitate accurate fuel pressure logging during tuning. Designed as a direct-replacement for OEM rails, they accept Bosch EV14-style injectors and offer easy bolt-on installation - ideal for LS engine swaps, forced induction builds, or high-flow fueling upgrades.

Backed by DeatschWerks' 3-year warranty, these rails offer long-term reliability and functionality. Whether for street, off-road, or track, the 7-206 rails are a robust foundation for any LS performance build requiring enhanced fuel delivery capabilities.
