Block Guards
Supertech block guards are designed to reinforce open deck cylinder blocks, reducing cylinder wall flex and distortion under high boost and high horsepower conditions. By supporting the top of the cylinder bores, a block guard helps maintain head gasket sealing and ring seal in heavily modified engines.
Machined to precise tolerances for a proper fit, Supertech block guards are an affordable insurance policy for boosted open deck engine builds.
