Shaft Rocker Systems
Probe Industries Shaft Rocker Systems
offer exceptional rigidity and stability when compared to conventional stud mounted rocker systems. Shaft systems also ease access to the valve train, facilitating valve adjustments and other maintenance functions. Probe Industries Shaft Rocker Systems are CNC machined of 2024-T3511 aluminum and feature dual needle roller bearings. The shafts are manufactured of aircraft certified steel. Also the stands on all Probe Rockers are made of steel for increased stability. Probe Industries Shaft Rocker Systems use a pair of 1,100 foot pound capacity Torrington captured needle bearings.
