Upgrade your Small Block Chevy engine with the Sportsman Racing Products 139629 forged piston set. Designed for performance applications, these pistons feature a dished crown with a minus 16.00 cc volume to help support compression ratio tuning and efficient combustion chamber setup. The 4.040-inch bore size is suited for compatible SBC engine builds requiring precision-fit replacement or performance pistons.
The pistons are manufactured from forged material for strength and durability under demanding operating conditions. A 1.425-inch compression height supports proper piston-to-deck and rotating assembly configuration when matched with the correct connecting rods, crankshaft, and engine block specifications. The inverted dome design provides additional clearance and combustion volume for builders configuring custom Small Block Chevy combinations.
Each piston is machined with 1/16-inch, 1/16-inch, and 3/16-inch ring grooves for compatible piston ring installation. This Sportsman Racing Products set includes eight pistons, making it suitable for a complete V8 engine rebuild or performance assembly. Confirm bore, compression height, ring package, pin specifications, and final clearances before installation to ensure compatibility with your application.
