Supertech Performance BG-D16ZC Block Guard Aluminum CNC Machined - 6061

The Supertech Performance BG-D16ZC Block Guard is a precision-engineered cylinder wall support solution designed for high-performance and heavily modified engines. Supertech block guards are meticulously designed and rigorously tested to provide structural reinforcement to cylinder walls operating under extreme stress conditions.

Unlike solid block guards that can trap heat and cause overheating issues, the Supertech BG-D16ZC features an optimized design that allows sufficient coolant flow through critical areas, effectively eliminating destructive cylinder hot spots while maintaining the structural integrity of the block.

Key Features:

• Manufactured from high-strength 6061 aluminum alloy for excellent durability and corrosion resistance
• CNC machined for precise fitment and consistent installation
• Reinforces highly stressed cylinder walls in performance and forced-induction applications
• Engineered coolant passages maintain optimal engine cooling in critical areas
• Prevents cylinder wall flex that can lead to ring seal loss and blow-by
• Reduces the risk of cracked or damaged cylinder walls under high boost or high-compression conditions

The Supertech BG-D16ZC is an ideal upgrade for turbocharged, supercharged, or high-compression builds where factory cylinder wall rigidity is insufficient. CNC machining ensures a precise, rattle-free fit for straightforward installation during engine assembly.
