This is a set of 4 ZZP 4340 forged connecting rods for your 2.0L LSJ, LNF, LDK, or LHU. While the Ecotec has been a great performing engine in stock form, as we continue to push these engines farther a forged rod solution is needed. Stock rods are safe up to around 450-500wtq, even less for the LDK/LHU which can break even on a stock turbo. These rods are made with forged 4340 steel and are a traditional H-beam style, made to withstand large amounts of power and RPM.
All of our rods are magna-fluxed, 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.
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.
Fits the 2.0L LSJ & LNF.
Note: Will not work with stock pistons, you must use forged pistons.
