ICON PISTONS IC448CKTS.STD ICON PISTONS IC448CKTS.STD Forged Flat-Top Piston and Ring Set for Mopar RB-Series, 4.500-Inch Bore

The ICON PISTONS IC448CKTS.STD piston and ring set is designed for Mopar RB-Series engine applications requiring dependable forged-piston performance and a matched ring package. This kit includes flat-top forged pistons engineered for a 4.500-inch bore, providing a durable foundation for performance, restoration, and high-output engine builds. The flat-top configuration supports flexible compression-ratio planning and is suited to combinations where precise piston design and consistent fitment are important.
The pistons feature a 1.355-inch compression height and a minus 6.40 cc volume specification, helping engine builders accurately calculate compression and optimize the complete rotating assembly. Each piston uses ring grooves configured for 0.043-inch, 1/16-inch, and 3/16-inch rings. The included rings provide a matched solution for the piston set, simplifying component selection and helping promote consistent sealing when installed with the appropriate cylinder preparation and assembly procedures.
Manufactured under the ICON PISTONS brand, part number IC448CKTS.STD is a practical choice for builders seeking a forged piston and ring kit tailored to Mopar RB-Series applications. The kit format helps streamline engine assembly by combining the primary piston and ring components in one package. Always verify crankshaft stroke, connecting-rod length, deck height, cylinder finish, clearance requirements, and final compression ratio before installation to confirm compatibility with the intended engine build. Professional installation and careful measurement are recommended for reliable results.
