COMP Cams Magnetic Deck Checker Underwear Steering StudTo calculate true compression ratio it's necessary to measure the distance between the deck surface of the block and the piston deck. Our machine aluminum deck checker incorporates magnets to hold itself firmly to the block for simple and accurate measurements.
