Strengthen the bottom end of your BMW M50 engine with the our M50 Engine Girdle —designed for serious performance builds and high-stress applications.

Key Features

  • Engineered Reinforcement: Adds structural integrity by securing all main caps, reducing the risk of cap walk and block flex under high RPM or boost conditions.

  • Precision Machined Construction: Laser-cut from high-grade 6 mm thick steel and machined chromoly spacers, ensuring a perfect fit and rigidity under load.

  • Includes Upgraded Hardware:

    • ARP fasteners and washers, offering high tensile strength and longevity—ideal for boosted or high-horsepower builds.

  • OEM Fitment: Designed to lock directly to the block and oil pan, creating a rigid sandwich assembly that drastically reduces movement.

Ideal For

  • Turbocharged or highly tuned M50 engines (especially those exceeding stock power levels).

  • Circuit, drift, and track cars where engine block bracing is critical.

  • Long-term reliability builds that demand tighter bottom-end tolerances.

Installation Notes

  • Minor clearance modifications—typically around the oil pump or windage tray—may be required.

  • Drilling and tapping the block and countersinking the plate is highly recommended for rigidity and eliminating leaks
