Supertech Performance BG-B20 Block Guard High Strength Aluminum

The Supertech Performance BG-B20 Block Guard provides critical support to highly stressed cylinder walls while maintaining optimal engine cooling. This precision-engineered component is designed to prevent destructive cylinder hot spots by strategically allowing coolant flow in critical areas while reinforcing the block structure.

Key Features:

• Constructed from high-strength 6061-T6 aluminum alloy for superior durability and corrosion resistance
• CNC machined to exacting tolerances for precise installation and perfect fit
• Engineered water jacket design balances structural support with adequate coolant circulation
• Reinforces cylinder walls in high-boost and high-horsepower applications
• Prevents cylinder wall deflection and distortion under extreme combustion pressures

Ideal for racing engines, turbocharged builds, and high-performance applications where cylinder wall integrity is critical. The BG-B20 block guard has been extensively tested across multiple engine platforms to ensure reliable performance under the most demanding conditions.
