{"product_id":"ls3-h-beam-rod-and-drop-in-piston-combo","title":"LS3 H-Beam Rod and Drop-In Piston Combo","description":"The Texas Speed H-Beam Rod and JE LS3 Drop-In Piston Combo is engineered for high-performance LS3 builds, offering a robust rotating assembly. This kit combines Texas Speed Performance (TSP) Super H-Beam connecting rods, constructed from heat-treated and stress-relieved 4340 steel, with JE Performance pistons specifically designed for the GM LS3 engine. These JE pistons are a direct drop-in for the LS3 and do not require balancing when used with TSP H-Beam Rods and a stock GM LS3 crankshaft.\n\nThe pistons feature a 4.065\" bore, a 1.300\" compression height, and a 3.622\" stroke, with a flat top design and valve reliefs for compatibility with various cylinder head and camshaft combinations. The Super H-Beam rods are precision-machined and rated for builds up to approximately 900 flywheel horsepower, incorporating ARP L19 rod bolts for enhanced clamping force and reliability. The manufacturing process for the rods includes multiple torque and honing stages to ensure exceptional roundness upon installation.\n\nThis combo is ideal for both naturally aspirated and boosted LS3 applications seeking increased strength and durability. Included in the kit are rod bearings and a file-fit ringset, simplifying the assembly process. However, it is crucial for the end-user to verify ring gaps, piston-to-wall clearances, and bearing clearances prior to final assembly to prevent engine damage. Additionally, piston-to-deck and piston-to-valve clearances must be checked with your specific head\/gasket\/rod combination. Blocks equipped with piston oil squirters may require clearancing, and users should follow ARP and TSP torque specifications during assembly.","brand":"Texas Speed","offers":[{"title":"Default Title","offer_id":52663967416632,"sku":"25-JELS3DropIn","price":1849.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687140797.webp?v=1784331343","url":"https:\/\/store.motormia.co\/products\/ls3-h-beam-rod-and-drop-in-piston-combo","provider":"MOTORMIA","version":"1.0","type":"link"}
