RAM billet aluminum flywheels deliver maximum performance, reduced rotating mass, and exceptionally quick engine response. Each aluminum flywheel is CNC machined from premium billet material, surface ground for absolute flatness, and dynamically balanced to precise tolerances. The lightweight aluminum construction significantly decreases rotational inertia, enabling faster rev matching, sharper throttle response, and improved acceleration in high performance or competition focused applications.
RAM aluminum flywheels feature a replaceable ¼\" steel friction surface, a fully serviceable ring gear, and are built to meet all SFI safety specifications. Application specific designs support today’s most popular engine swap platforms—including LS, LT, Coyote, and Hemi—as well as Tremec transmission conversions. For drivers and builders seeking the fastest engine response and the advantages of reduced rotating mass, RAM billet aluminum flywheels deliver a proven edge on the street, strip, or track.
When your project demands the lightest, quickest revving solution without compromising durability, choose RAM billet aluminum flywheels for unmatched precision, responsiveness, and reliability.
