Construction & Design

The ARP carburetor spacer stud kit is crafted from high-strength 8740 chromoly steel, known for its excellent tensile strength and durability. The studs are precision-machined to exact specifications, ensuring a perfect fit and reliable thread engagement. The drilled design for wire seals enhances sealing capabilities, making it suitable for high-performance and racing engines where maintaining vacuum integrity is critical.

The inclusion of a 2-inch Moroso spacer adds volume to the intake manifold, which can help improve airflow dynamics and throttle response. The spacer's design promotes even distribution of air and fuel mixture, contributing to more efficient combustion. The nut-starter radius feature on the studs reduces the risk of cross-threading, allowing for easier installation and removal, especially in tight engine bays.

Installation & Fitment

The ARP Drilled Carburetor Spacer Stud Kit is designed for straightforward bolt-on installation. It is compatible with most carbureted engines requiring a secure and properly aligned mounting system. The studs are engineered to thread into the intake manifold, with the carburetor mounted on top using the included hardware. No cutting, drilling, or special tuning is typically required, making it suitable for both novice and experienced mechanics.

• Ensure compatibility with your specific carburetor and manifold before installation.
• Use appropriate tools to tighten the nuts to the recommended torque specifications to avoid over-tightening or damage.
• Check gasket alignment and sealing after installation to prevent vacuum leaks.
