McLeod Flywheel Aluminum Chevy 1955-85 SB & All BB W/11inLong Patt 168

This McLeod aluminum flywheel is built for Chevy small-block and big-block engines, specifically those from 1955 through 1985 and all big-blocks with the 168-tooth ring gear and 3/8 inch Ford long pattern. It's designed for applications where rapid engine speed changes are common, like those found in supercharged or turbocharged setups, or any high-horsepower combination. This flywheel weighs in at 15 lbs, making it lighter than a stock cast iron unit, which helps the engine rev up more quickly.

Precision CNC machined from 6061 T6 aluminum, this flywheel offers a strong yet lightweight foundation. It includes a replaceable steel friction plate, so you can easily service it down the road without replacing the entire unit. The hardened 1045 steel ring gear is also built for durability. This flywheel meets SFI specifications, meaning it's rated for competition use and is designed to contain potential failures.

This flywheel is compatible with a wide range of Chevrolet vehicles, including models like the Bel Air, C10 Pickup, and Impala from the mid-50s through the mid-80s, as well as later C1500 and C3500 models. It's designed for engines with a 2-piece rear main seal and is internally balanced. If you're building a performance engine that needs to respond quickly to throttle input, this aluminum flywheel is a solid choice.
