Overview 

From the factory the oil supply to the rocker arm is shut off as the valve is opened, this lack of lubrication can cause excessive wear on your valvetrain and premature failures especially in high performance applications. The XDP shafts feature revised oil grooves that align with the oil hole in the bushing so you maintain a consistent oil supply. These shafts are manufactured from hardened 4130 chromoly for extreme durability, each shaft comes ready to install and has threaded pipe plugs at each end so the shafts can be cleaned, inspected and hot tanked during an engine rebuild.
