MAIN GIRDLE - With Dowels & Main Studs

Our girdles provide additional support points below the crankshaft and tie all the caps together substantially reducing any possibility of flexing or twisting. When the engineers at Honda designed the higher revving B18C engine they took this support issue into account thus designing the 3 main girdle only found in B18C and the rare B16B blocks. The awesome thing about these girdles is you can use your existing caps. Although you do need B18C ARP main studs to mount the girdle along with Align Bore machine work.
