4150 Sec. Conn. Rod Kit

The Holley 4150 Secondary Connecting Rod Kit is a critical component for boaters maintaining or upgrading their marine carburetor systems. This specific linkage rod is engineered to facilitate the mechanical synchronization between the primary and secondary throttle plates, ensuring that your engine receives the precise fuel-air mixture required during high-demand acceleration. For those looking to buy a replacement or keep a spare in their onboard toolkit, this kit provides the exact specifications needed for Holley 4010 and 4150 series carburetors.

Constructed from high-strength steel, the Holley 4150 Secondary Connecting Rod Kit is built to withstand the constant mechanical stress of throttle cycles. In the harsh marine environment, where salt spray and humidity are constant threats, the cadmium plating on this rod provides an essential layer of corrosion resistance. This finish ensures the linkage remains smooth and free-moving, preventing the binding issues that can lead to unpredictable engine performance or safety concerns while navigating open water.

This rod is designed specifically for manual secondary applications, giving the operator direct control over the opening of the secondary barrels. When reviewing the specifications for your carburetor rebuild, ensuring the correct linkage geometry is paramount. The Holley 4150 Secondary Connecting Rod Kit maintains the tight tolerances required for consistent secondary engagement, which is vital for maintaining the performance and reliability of high-performance marine engines.

Each Holley 4150 Secondary Connecting Rod Kit is sold as a single unit, making it a straightforward solution for targeted repairs. By utilizing factory-spec components, you avoid the risks associated with universal or modified parts that may not align perfectly with the 4010 or 4150 bodies. This component is an essential acquisition for any owner prioritizing long-term durability and mechanical precision in their vessel's fuel system.
