{"product_id":"forged-4340-h-beam-connecting-rods","title":"Forged 4340 H-Beam Connecting Rods","description":"The SpeedFactory Racing No-Notch H-Beam Long Rod and Vitara Piston Combo is a performance upgrade for Honda\/Acura D16 (ALL) \u0026amp; ZC engines. This package includes SpeedFactory Racing's \"No-Notch\" H-beam connecting rods and Vitara pistons, designed to achieve a 8.8:1 compression ratio, a significant increase from the 7.8:1 yielded by standard-length rods.\n\nThese custom-length connecting rods address common frustrations with D16 Vitara turbo builds (popular for 300-500hp). Unlike standard rods that require block and girdle notching, these \"No-Notch\" rods are profiled to clear factory girdles and sleeves, eliminating the need for tedious notching. The rods are constructed from forged SAE 4340 chromoly steel, offering high strength and quality at an affordable price. They are 100% CNC machined, heat-treated, magnafluxed, and shot-peened for stress relief. Precision alignment dowels ensure proper rod cap location and eliminate cap walk, while bronze alloy pin bushings accommodate floating wrist pins. Each rod set is balanced to +\/- 1 gram and comes standard with 3\/8\" ARP2000 rod bolts rated to 220,000 psi. Instructions and ARP Lube are included.\n\nKey specifications include a center-to-center length of 138.63mm (5.458\"), a pin end bore of 19.02mm (0.748\"), and a big end bore of 48mm (1.890\"). The rods are rated for 500hp and are laser etched with the SFR logo.\n\nThis combo is specifically designed for the 1988-2005 Honda Civic and the 1986-1989 Acura Integra. It includes 4 pistons with rings and wrist pins, and 4 connecting rods. The product is covered by SpeedFactory's Standard Limited Warranty.","brand":"SpeedFactory Racing","offers":[{"title":"Default Title","offer_id":52663774249272,"sku":"SF-02-103 \u0026 YCP-75MMKIT","price":569.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687686821.png?v=1784329489","url":"https:\/\/store.motormia.co\/products\/forged-4340-h-beam-connecting-rods","provider":"MOTORMIA","version":"1.0","type":"link"}
