Mid Motor Plate - GM LS Engines - Steel .090

The Mid Motor Plate for GM LS Engines from Competition Engineering is a precision-engineered steel component designed for engine builders and fabricators tackling mid-mounted LS powerplant installations. Whether you're constructing a tube-chassis race car, kit car, or exotic mid-engine project vehicle, this motor plate serves as the structural foundation that securely anchors your LS engine to the frame. Built from .090-inch steel stock, it provides the rigidity and load-bearing capacity necessary to handle the stresses of high-horsepower applications while maintaining alignment and stability during acceleration, braking, and cornering.

Competition Engineering's motor plate is manufactured to exacting tolerances, ensuring precise fitment with GM LS engine mounting bosses and custom frame rails. The .090 steel thickness strikes an optimal balance between weight savings and structural integrity—light enough to minimize unsprung mass and support weight in mid-engine applications, yet robust enough to resist flexing under sustained load and vibration. The 36.3-inch length accommodates full-length mounting surfaces, while the 14.8-inch width provides broad lateral support across the engine block. Competition Engineering's engineering ensures proper load distribution, reducing stress concentration at mounting points and extending component lifespan in demanding motorsports and fabrication environments.

This mid motor plate is essential for professional fabricators, race teams, and enthusiasts building LS-powered mid-engine vehicles, including custom sports cars, tube-chassis racers, and specialty builds where stock mounting provisions don't apply. Installation requires proper alignment with your frame structure and LS engine block—careful setup is critical to prevent vibration and ensure uniform bearing loads across all mounting points. At 5.9 pounds, the plate remains lightweight while delivering the strength needed for high-performance applications, making it ideal for builders prioritizing both structural reliability and weight management. Verify all mounting hole patterns against your specific frame and engine configuration before fabrication to ensure seamless integration.
