Product Details
Starting with a .165" wall thickness, this dual taper 7/16" diameter 8.450" long pushrod from COMP Cams offers the clearance of a 3/8" pushrod while maintaining the rigidity of a larger diameter. This design is particularly helpful in applications where extra clearance is needed, such as around rocker arm adjusters at peak lift, or to clear the top of most offset roller lifters. The thicker .165" wall is stiffer and stronger than previous .125" wall offerings, which translates to more accurate valve motion and better durability over time.
These pushrods are constructed from one-piece, heat-treated 4130 chromemoly steel tubing, a material known for its strength, making them a strong option compared to many other pushrods on the market. Both 5/16" ball ends feature a 210° radius, designed to provide additional clearance to the rocker arm adjuster at peak lift. They are made in the U.S.A. and are a solid choice for those looking to improve valve train accuracy and longevity.
