GRP connecting rods are CNC machined from a special aluminum alloy plate that provides a combination of high strength, high fracture toughness and great resistance to fatigue crack propagation at high stress levels that todays racing engines are constantly operating in. The manufacturing process takes advantage of the CNC's capability in that the rod is custom built around the actual center to center distance, resulting in custom length rods being a matter of just inserting the new center to center distance. These rods are then honed to size, holding a +/- .0002" tolerance, and from that finished bore the final center to center distance is cut holding a +/- .0002 tolerance in the center to center distance of the rod. The rods are then polished with a high energy finishing machine to remove stress risers and to give the rod a durable polished finish. CALL OR EMAIL WITH YOUR ENGINE APPLICATION FOR PRICING.
