Use Stage I for mildly modified engines, Stage II for turbo or power-added engines, Stage III for competition engines operating under high stress. Displaying robust forged cup ends, Trend pushrods are believed to be the first one piece pushrods to suit Cummins 12v and 24v and 6.6L Duramax diesel engines. They are produced from 4130 chrome molybdenum and heat treated to around Rockwell Rc60. Their advantage lies in their strength and rigidity; thus they handle higher spring pressures and contribute greater resistance to deflection. For Ford's 6.0L and 6.4L Power Stroke diesels Trend has introduced four new 11/32in pushrods with wall thicknesses of 0.080in and 0.135in. For the larger 7.3L engine, 7/16in diameter with 0.080in wall and 0.165in wall are available. OEM stock lengths for all three series are now offered as shelf-stock items.
