Supertech Performance BG-D17 Block Guard Aluminum CNC Machined - 6061

The Supertech Performance BG-D17 Block Guard is a precision-engineered cylinder wall support insert designed for high-performance and forced-induction engine builds. Manufactured from 6061 aluminum alloy and CNC machined to tight tolerances, this block guard installs with precision and provides critical structural reinforcement to the cylinder walls under extreme operating conditions.

Supertech block guards are engineered to support highly stressed cylinder walls while maintaining optimal coolant flow through critical areas of the engine block. The design allows adequate water circulation around the cylinders, preventing destructive hot spots that can lead to detonation, bore distortion, or premature engine failure.

Key Features:

• Constructed from high-strength, corrosion-resistant 6061 aluminum alloy
• CNC machined for precise, consistent fitment
• Supports cylinder walls under high-boost and high-stress conditions
• Engineered coolant passages maintain water flow to critical areas
• Reduces the risk of cylinder hot spots and bore distortion
• Meticulously designed and validated across multiple engine applications

The Supertech BG-D17 block guard is an essential upgrade for any serious engine build where cylinder integrity and thermal management are top priorities.
