ZZP 2.0 4340 Connecting Rods
All of our rods are magnafluxed, heat treated, stress relieved, shot peened, and sonic tested to ensure they provide the strength required for high horsepower applications. Our exclusive “no twist” machining processes guarantee the most accurate pin end to big end parallelism in the industry. We weight match all of our sets of rods to + or -1.5 grams to make balancing easier. Silicon bronze bushings are installed for use with floating pins. Bolt lube and torque specifications are included. ZZPerformance rods are also equipped with ARP 2000 bolts and are rated for 800 horsepower.
The LSJ version of this rod was tested in Ryan's 2006 Cobalt to 898WHP w/o failure!
Torque spec is 55 ft-lbs with ARP lube.
From the factory, tangs are installed facing exhaust side so we do the same. The rods are symmetrical it does not matter which side they face.
