Fixed Length 4130 Chrome moly one piece pushrods with swedged formed ends. Heavy duty 7/16 diameter tube with 0.165 wall thickness, precision concentricity, heat treated with a black oxide finish. Intake and Exhaust pushrods are stock replacement lengths and designed to work with the factory base circle camshaft dimensions. These pushrods work with Feuling 525, 543, 574 cam grinds.
Quick install pushrods are said to be easier to use, however they cannot compare to a solid pushrod for strength and durability
Note: For large lift smaller base circle camshafts see Feuling #4073 which are 0.030 longer
