Pushrods Some parts are not legal for sale or use in California or other states with similar laws/regulations—see pg. 2 for details. WARNING: For Proposition 65 information, see pg. 2 Adjustable Pushrod Length Checkers These 5/16" pushrod checkers feature over 1" of travel to help determine proper pushrod length for any application. A must-have tool for setting proper valvetrain geometry, they’re made from thinwall steel and have 5/16" ball ends.

Trick Flow one-piece chromoly pushrods are available in a variety of lengths for use with any Trick Flow cylinder head as well as other OEM and aftermarket heads. Designed specifically for high performance applications, the pushrods have the following features: • Cold-formed from 4130 chromoly steel construction • .080" wall thickness • Induction-hardened heat-treating for use with guideplates In addition, the oil hole is closed to within .040" then drilled and chamfered to .093". This eliminates stress fractures and cracks caused by the cold-forming process. NOTE: Always check the proper pushrod length for the specific application before ordering.

For maximum valvetrain efficiency, rocker arm tip travel on the valve stem should be .080" or less. As a rule, longer pushrods will decrease rocker arm tip travel. If you can’t get a tip travel measurement of .080" or less after trying several pushrod lengths, you will have to switch to another brand of rocker arms and start over. When checking pushrod length with roller tip rocker arms, note the position of the roller tip on the valve stem when the valve is at one-half of its net lift. Ideally, the centerline of the rocker arm’s tip should coincide with the centerline of the valve at one-half of its net lift so the rocker arm tip travels an equal distance on each half of the valve stem tip. If you have questions about checking pushrod length or pushrod/ rocker arm recommendations for your combination, contact the Trick Flow Technical Department at 1-330-630-1555, Monday through Friday from 9:00 am to 5:00 pm EST. Pro-Calibrated Adjustable Pushrod Length Checkers Made from high-quality steel alloy with a durable black oxide coating, Trick Flow’s pro-calibrated adjustable pushrod length checkers are the most accurate way to measure pushrod length. They work like this: The range length number on each checker represents the overall length it can measure through one full inch of extension. A laser-etched alignment line identifies each full rotation position, and grooves every .050" on the inner sleeve keeps count of the number of rotations made. For example, when a 7.800"-8.800" length checker in its shortest position is turned apart by one rotation, the length grows to 7.850" (7.800 + .050 = 7.850). Therefore, that dimension would be the correct length pushrods to order. Available in ball tip and cup tip versions from 5.800" to 12.800" overall length.

They are available in any length from 6.250"–9.000" (5/16") or 7.650"– 9.950" (3/8") in .050" increments by building a pushrod part number. Just add the length desired to the end of the part number code. Here’s how: To order 5/16" pushrods use the base number: TFS-2140____ and add the length. For example: TFS-21406250 designates 5/16" diameter, 6.250" pushrods. To order 3/8" pushrods use the base number: TFS-2141____-8 and add the length. For example: TFS-21419000-8 designates 3/8" diameter, 9.000" pushrods.
