Designed for performance-focused builds, these forged pistons feature a domed crown that helps increase compression and support improved power potential when matched with the appropriate cylinder heads, combustion chamber volume, and engine components. The set includes eight pistons for a complete V8 application.\u003cbr\u003eThe 139531 pistons are engineered for a 4.310-inch bore and feature a 1.645-inch compression height for compatibility with properly configured Big Block Chevy rotating assemblies. Their +48cc dome volume provides a substantial compression increase, making them well suited to naturally aspirated racing and high-performance street applications where precise compression-ratio planning is essential. Always verify piston-to-valve clearance, deck height, connecting rod specifications, and final compression ratio before installation.\u003cbr\u003eEach piston is machined with 1\/16-inch, 1\/16-inch, and 3\/16-inch ring grooves to accept compatible performance piston rings. The forged construction provides the strength and durability needed for demanding engine environments, while the application-specific design supports reliable fitment when used with properly matched components. This Sportsman Racing Products piston set is a strong choice for builders seeking durable forged internals and increased compression in a Big Block Chevy engine.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Sportsman Racing Products\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: 139531\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Big Block Chevy V8 engines\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesign: High-compression domed piston\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstruction: Forged for performance engine applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBore Size: 4.310 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompression Height: 1.645 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDome Volume: Plus 48.00 cc\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRing Grooves: 1\/16 inch, 1\/16 inch, and 3\/16 inch\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eQuantity: Set of 8 pistons\u003c\/li\u003e\u003c\/ul\u003e","brand":"SPORTSMAN RACING PRODUCTS","offers":[{"title":"Default Title","offer_id":67644466102524,"sku":"SRP139531","price":787.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/8797\/5420\/files\/SRP139531.jpg?v=1791108729","url":"https:\/\/ozkonickustomz.com\/products\/sportsman-racing-products-139531-bbc-high-compression-domed-forged-piston-set-4-310-inch-bore-48cc","provider":"Ozkonic Kustomz LLC","version":"1.0","type":"link"}
