NOTE-**IF USING CROWER CAM LIFTERS, YOU CANNOT FIT A 3/8 PUSHROD ON INTAKE SIDE, ONLY A 5/16.** 1 Set of 16 - 3/8 Diameter By .095 Wall Thickness -Billet 8620 steel Tip End -4130 Chromoly Tubing -To provide increased pushrod column strength and valve train stability, we developed a 3/8 Drop in "3 Piece" pushrod. Our pushrods are manufactured with 4130/4135 seamless Chromoly tubing with a variety of heat treating conditions and wall thickness' available, all coming standard with our billet steel tip ends. These tips have been CNC machined from 86L20 bar stock that is then core hardened and triple tempered , providing increased impact and wear resistance. This combination of materials and heat treatment procedures will extend the service life of the pushrod, while improving overall performance of your valve train. Our versatility in engineering and design allows us to manufacture a product that will enhance the specific combination of your engine. When we sit down to engineer a pushrod, we always try to fit the largest diameter pushrod we can, within the space available. With the window we have to work in, the stock 5/16 diameter is Not the largest diameter pushrod that will drop right in without any modifications. However, by increasing the diameter of the tubing from the stock 5/16 to 3/8, we can spread the load over a larger surface area without causing the pushrods to bind with the port of the cylinder head or rockerarm body. The larger 3/8 diameter tube will provide almost two times more loading capacity than a 5/16 diameter before beginning to deflect. Larger diameter is always a better choice when it comes to pushrods. We take pride in knowing that we produce the highest quality parts available anywhere in the world. If you have a need for a pushrod for your 6.1 hemi different than the length listed, please call us and we will be happy to making it for you at no extra charge! Not for guide plate use!
