    Used the 221424 in endurance boat, done approx 500-600 miles & broke 1 outer
    221425 in bracket BBC with 288/304 cam, 7600 rpm, approx. 70-80 passes.
    They still held pressure but we replaced just as routine maintainance
    They are a good spring & there pressure did not fall off much at all once seated.
    Will continue to use them.
