Breathers are billet aluminum where it mounts to the valve cover with two .250" fasteners on a 3.750" bolt spread. These breathers use a quick release pin that you simply pull and it snaps back in on a spring so there is no chance of losing the pin to remove the hoses so valve adjustment is made easy between rounds.
The breathers use a billet anodized hose coupler that is O-ringed to provide superior seal and the coupler accepts 1.250" hose. Both breathers are turned out ten degrees to make running the hose to the breather tanks a simple chore.
These are perfect for clearing a magneto on a Hemi or AJ 481X and give the top of the motor symmetry with there ten degree angle.
Burn downs are sold in a pair and hose ends are purchased separate under #2600-0015.
These breathers are 3.125" tall from mounting surface to top.
