Abstract
An improved frame height gauge for race cars includes a substantially hollow housing having an open top end. A spring urges a stop member pivotally mounted within the housing to an extended position in which the stop member projects through the top opening. In use, an individual slides the gauge beneath a frame portion of a race car at a location to be measured, causing the stop member to contact a portion of the race car frame, depressing the stop member against the bias of the spring into the housing to a depressed position in which the distance from a bottom surface of the housing resting on the ground or a floor to the uppermost extending portion of the stop member corresponds to the car frame height at the particular location. The stop member and housing include cooperating detent members operative to selectively retain and release the stop member from the depressed condition, allowing a user to remove the gauge from beneath the car, while still retaining an indication of the measured frame height on a scale inscribed or imprinted on the housing.
