Canton Racing Main Cap Girdles

Back in the day, Ford engine block castings held up fine against 220 hp--but you couldn't go racing! Canton Racing has designed these main cap girdles to reinforce the alignment of the main caps and counter the limited webbing and weaknesses of those stock blocks. These main cap supports are laser-cut from 1/2 in. to 5/8 in. steel and feature CNC-machined mounting holes and rod notches for stroke clearance. Canton Racing main cap girdles tie directly to the caps, eliminating the need for bushings, spacers, or machining of the main caps for installation.
