Connecting Rod: Description and Operation
ROD-PISTON & CONNECTINGDESCRIPTION
The pistons are made of cast aluminum with an added anodized coating on both sides of the skirt and the top piston ring groove for reduced wear and it's low friction properties. Three piston rings are used; two compression and one three-piece oil control ring. The piston pin (press-fit into the rods) joins the piston to a forged steel, fractured cap, designed connecting rod, with a custom twelve point nine millimeter threaded bolt. The piston and connecting rod is serviced as an assembly and is not interchangeable with previous model years.
