GRP PRO 5500 Series Custom Aluminum Connecting Rods Set/8

GRP connecting rods are CNC machined from a special 7075 aluminum alloy plate that provides a combination of high strength, high fracture toughness and good resistance to fatigue crack propagation at high stress
levels. Our 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 honest +/- .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.

Pro series rods are made from a stronger aluminum than standard series

Comes standard with ARP 2000 Rod Bolts rated at 220,000psi

The rods are then polished with a high energy finishing machine to remove stress risers and to give the rod a durable polished finish.

**The average turn around time for a set of rods is about 2 weeks.**
