Eiahonen LS Drive By Cable Throttle Body Adapter Kit | 4-Bolt LS3 to 3-Bolt LS1 DBC Compatibility

Upgrade Flexibility for LS Intakes and TBs

The Eiahonen LS Drive By Cable Throttle Body Adapter Kit is engineered for versatility. Made from high-grade T6 aluminum and precision CNC machined, this adapter delivers a stable, lightweight interface that helps you explore different throttle body and manifold combinations without swapping the entire setup. By design, it bridges a 4-bolt LS3 intake to a 3-bolt DBC throttle body, paving the way for a cleaner upgrade path and a more streamlined engine bay appearance.

• High Quality: T6 aluminum construction and CNC precision ensure rigidity, lightness, and long-term durability for everyday use and occasional track days.
• Upgrade Flexibility: Enables mounting a 3-bolt DBC LS throttle body onto a 4-bolt LS intake, for example pairing an LS2/LS3 manifold with a 3-bolt TB.
• Broad Compatibility: Accepts throttle bodies up to 75mm and intake manifolds up to 92mm; not compatible with 3-bolt drive-by-wire TBs or LS4 intakes.
• Core Function: Supports interchangeability of throttle body designs across different engines, expanding your upgrade options without manifold changes.
• Installation Note: When mounting the LS3 4-bolt intake, ensure all retaining bolts are tightened properly to achieve a solid seal between the throttle body and the intake manifold.

In real-world terms, this adapter offers a practical path for experimenting with throttle response and airflow while preserving reliability. Enthusiasts can test alternative throttle bodies and manifold configurations, helping you evaluate performance and fitment without extensive component swaps. The interface emphasizes a secure seal and precise alignment, contributing to a neatly finished engine bay that’s ready for tuning and refinement.
