{"product_id":"4340-h-beam-connecting-rod-set-2-0l-ecotec","title":"4340 H-Beam Connecting Rod Set, 2.0L Ecotec","description":"The ZZPerformance 4340 connecting rods are a robust upgrade for 2.0L Ecotec engines, specifically the LSJ, LNF, LDK, and LHU, designed to handle significant increases in power and RPM beyond stock capabilities. Stock rods are typically rated for around 450-500 wheel torque, with LDK\/LHU models being less capable even on stock turbochargers. These ZZP rods are constructed from forged 4340 steel in a traditional H-beam configuration, ensuring durability under demanding conditions.\n\nEach rod set is subjected to comprehensive quality control measures, including magna-fluxing, heat treatment, stress relieving, shot peening, and sonic testing. This ensures they meet the rigorous strength requirements for high-horsepower builds. ZZPerformance employs exclusive \"no twist\" machining processes to achieve superior pin end to big end parallelism. Furthermore, each set is precisely weight-matched to within +\/-1.5 grams, simplifying the engine balancing process. Silicon bronze bushings are installed, accommodating floating wrist pins.\n\nInstallation requires careful attention to torque specifications: 55 ft-lbs with ARP lube is recommended. The tangs are factory-oriented towards the exhaust side, and this orientation is maintained on the ZZP rods. It is crucial to note that these connecting rods will not work with stock pistons; forged pistons are a mandatory requirement for compatibility with this setup.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52689674895672,"sku":"ZZ-4340RDS-20","price":479.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687424407.webp?v=1784909028","url":"https:\/\/store.motormia.co\/products\/4340-h-beam-connecting-rod-set-2-0l-ecotec","provider":"MOTORMIA","version":"1.0","type":"link"}
