Our Ford main supports counter the limited webbing and weakness of the stock blocks. They help to “beef up” your lower end by reinforcing the alignment of the main caps. Each support is laser cut from 1/2" (302) or 5/8" (351W & 460) steel and features CNC machined mounting holes and rod notches for stroke clearance. Our design ties directly to the main caps and doesn’t need bushings or spacers or require the main caps to be machined to mount it. All mounting bolts and washers are included. Main supports are predrilled to accept the mounting of our optional louvered windage tray.
