HAMILTON CAM 2003-2007 6.0L STREET/STRIP PUSH RODS

Description

The pushrod is a very important and often overlooked component in any high horsepower build. It doesn’t have to do a much, just transmit lift from the lifter to the rocker arm, and bend or deflect as little as possible. Reducing mass in an engine is almost always a good thing however there are a few places, in order to work correctly under high stress, that require a super rigid part. The problem is that more rigidity almost always means more mass. In these applications that require a super rigid part, pushrods, rods, wrist pins etc., to reduce mass would be to get a part that either doesn’t live long, or a part that reduces performance.

There are ways to get a strong part with better design and better materials without gaining mass in some instances. But that mindset too often means one-off designs and exotic materials, and that means a lot of money. In the pushrod world there is a small group of materials that work best for the given mass. Mainly performance pushrods are made from a form of chromoly. Ours are no different being made of 4130 chromoly with hardened 8620 pressed in ends.

Now here is where the rubber meets the road. Factory pushods are rated at 1794 lbs, Brandx 1982 lbs. Hamilton 3/8″ 2064 and Hamilton 7/16″ 4035. over 500rearwheel horsepower you at least need the 3/8 .095 wall over 630Rwhp you really need to jump to the 7/16″ .120″ wall. If you don’t the pushrod deflects first then opens the valve. It delays the valve opening which reduces spool and power. If you are a low budget street racer you will not notice much difference in spoolup or major power but if you are racing or sled pulling and want to make sure you don’t snuff that big charger at the big end, use a better pushrod to open the exhaust on time at full power and full cylinder pressure. It will help the chargers stay lit by not retarding the exh opening.
