The McLeod Racing 460320 Steel Flywheel is a lightweight, performance-focused upgrade for classic Chevrolet builds. Designed for 1955–85 Small Block Chevy (2-piece rear main) and 1970–90 Big Block Chevy (large register) applications — including select 1991-up BBC engines — this 153-tooth, 20 lb billet steel flywheel delivers responsive acceleration and dependable street performance.
 
Engineered for internal balance combinations, the 20 lb design improves throttle response while maintaining smooth engagement. Precision CNC-machined from high-strength billet alloy steel and equipped with a hardened 1045 steel ring gear, it’s built for durability in both street and mild race applications.
 
This flywheel features a 10.5" Borg & Beck or diaphragm clutch pattern, making it ideal for compact bellhousing and starter configurations requiring the 153T diameter. (Additional counterweight kit 560222 required where applicable.)
 
For customers of Silver Sport Transmissions, the McLeod 460320 provides proven strength, precise balance, and lightweight performance for SBC and BBC manual transmission builds.
