Securing your engine with rigid, zero-flex performance parts is the foundation of a podium-winning racing chassis. The Trackside Karting 2PMFA Flat 2-Piece Motor Mount delivers a zero-degree, dead-flat platform specifically engineered for American rail spacing (2-7/8" center-to-center) on frames up to 1.125 inches. By eliminating the engine angle, this mount ensures a lower, more balanced center of gravity, which translates to even traction distribution across the rear axle—a vital advantage when navigating high-speed sweepers or tight technical sectors.
Seamless Integration for Your Motor Cart
Building a competitive motor cart requires precision at every mounting point. The two-piece modular design of this flat mount allows for rapid installation and lateral adjustments without binding the chassis. Whether you are swapping engines between heats or fine-tuning your chain alignment, the independent base blocks slide smoothly along the rails. This flat orientation is highly favored by builders running specific drivetrain configurations, ensuring that components like a go kart torque converter or a standard centrifugal clutch align flawlessly with the rear sprocket, reducing parasitic drag and chain wear.
Fuel System and Carburetor Clearances
Engine positioning directly impacts your intake and exhaust dynamics. A flat mount configuration keeps the engine block level, which is essential for proper float bowl operation in your carb for go kart applications. When running precision fuel delivery systems, such as a tuned lo206 carburetor kit, maintaining a level float height prevents fuel starvation during sustained lateral G-loads. This mount provides the rigid, vibration-resistant foundation needed to keep your intake manifold secure and your fuel mixture consistent from the green flag to the checkered flag.

Frequently Asked Questions
Q: Is this mount compatible with my kart frame?
A: This mount is specifically engineered for American rail spacing, which is 2-7/8" center-to-center. It is designed to clamp securely onto frame rails with a maximum diameter of 1.125 inches.
Q: Why should I choose a flat mount over an angled mount?
A: A flat (zero-degree) mount is ideal for maintaining a lower center of gravity and ensuring your carburetor float bowl remains level. This is critical for consistent fuel delivery and preventing fuel starvation during high-speed cornering.
Q: How does the two-piece design help with installation?
A: The two-piece modular design allows you to adjust the base blocks independently. This makes it much easier to align your clutch and sprocket perfectly, reduces the risk of chassis binding, and simplifies the process of swapping engines between heats.
Q: Will this mount help with chain wear?
A: Yes. By providing a true-flat reference point, this mount ensures your clutch and rear sprocket are perfectly aligned. Proper alignment significantly reduces parasitic drag and prevents premature chain and sprocket wear.
Q: Does this mount come with the necessary hardware?
A: The mount features pre-tapped holes sized for standard mounting bolts to ensure maximum clamping force. Please ensure you have the appropriate length bolts for your specific engine block thickness.
