SM Lifters require NO treatment or break-in on stock cast iron cams, this has been
their success story for the last 15 years. You install them on your stock
untreated cam, using your race ready springs (no special motor oil required)No Break-in and go racing. There is No Cam Wear and you can change cams as often as you wish using the same lifters. Although these lifters work well on steel camshafts, save your money, you don't need a steel billet cam.
Failures like this are very common, our composite lifters eliminate this risk completely.
