Supertech Performance Block Guard Engine

Supertech Performance Block Guards are CNC-machined aluminum cylinder wall supports for open deck engine blocks. Also called block guards, cylinder sleeve supports or open deck block reinforcements, they fill the gap between the outside of the cylinder wall and the rest of the block. The added rigidity helps reduce cylinder wall flex, movement and cracking.

Key Features:

• 6061 aluminum alloy: high-strength, corrosion-resistant construction.
• Cylinder wall support: helps limit bore flex and distortion in highly stressed engines. This helps maintain head gasket and ring seal.
• Cooling-focused design: allows enough coolant flow through critical areas to help avoid destructive cylinder hot spots.
• Computer designed and CNC machined: built to precise tolerances for a proper fit and easier installation.
• Engine-specific designs: the line is offered in application-specific versions for popular open deck engines.

Supertech Performance is known for engine valvetrain and internal components. Its block guards are designed to work alongside its other engine components. Installation is normally done during block machining and engine assembly, ideally by a qualified machine shop.
