Mag Rear Motor Plate

The Mag Rear Motor Plate (SRC-2860) by Diversified Machine is a precision-engineered engine mounting component designed for high-performance automotive builds and engine swaps. This rear motor plate serves as the critical structural interface between your engine block and transmission assembly, maintaining rigid alignment under acceleration, braking, and sustained load conditions. Whether you're completing a classic car restoration, installing a modern performance engine, or reinforcing a modified drivetrain, this plate distributes stress evenly and prevents parasitic vibration that degrades bearing life and driveline integrity.

Manufactured from high-strength steel, the Mag Rear Motor Plate weighs 7.15 pounds and measures 21 × 0.75 × 36 inches, providing substantial material thickness and broad mounting surface area for superior load distribution. The plate's design accommodates standard engine block bolt patterns while offering reinforced geometry that resists flex and deflection during peak torque events. Its compact depth allows installation without major modifications to existing engine bays, and the flat, finished surfaces accept standard fasteners and clearance adapters. The generous 36-inch length spans the full width of most engine compartments, ensuring balanced support across the entire motor mount interface.

Fabricators, performance shops, and serious enthusiasts rely on the Mag Rear Motor Plate when upgrading engine mounts or addressing driveline harmonics in turbo conversions, V8 swaps, and high-output builds. Installation typically requires basic hand tools and familiarity with engine bay layout; positioning the plate parallel to the block face ensures optimal vibration isolation and extends the service life of transmission bushings and cross-member components. This component is essential for applications where factory mounts are insufficient or where custom motor mount geometry demands a rigid backing surface. Verify bolt hole spacing and engine block configuration against your specific platform before ordering.
