Crankshaft big end journals must be ground to suit.

Billet steel H-beam connecting rods for Volvo B18 engines. These are a longer con rod only suitable for our short crown forged pistons.

We use these rods in all of our B18 Volvo race engines. The big end is sized to use a special bearing. The crankshaft must be ground to suit. Big end bearings are available separately in our shop.
