Our Supertech Block Guards are meticulously designed and tested in many engines. As a result we offer a product that will provide support to highly stressed cylinder walls with optimal engine cooling by allowing enough water flow in critical areas to avoid destructive cylinder hot spots.

Our block guards are made from high strength, high corrosion resistant 6061 aluminum alloy. All of our block guards are computer designed and CNC machined ensuring the best possible fit and making installation a breeze.
Supertech block guards are among the best in the industry and designed to work with all of our valvetrain components.
