The proper length pushrod is critical to achieving correct valvetrain geometry. Trick Flow one-piece chromoly pushrods are available in a variety of lengths for use with all high performance applications. The pushrods are cold-formed from 4130 chromoly steel with a .080" wall thickness for strength and durability. Plus, the oil hole is closed to within .040" then drilled and chamfered to .093" to eliminate stress fractures and cracks before being induction-hardened and heat-treated for use with guideplates. These pushrods are available in 5/16" diameter in any length from 6.250"-9.000" and in 3/8" diameter between 7.650"-9.950" in .050" increments.
