Flywheels

Flywheels

A performance flywheel reduces rotational mass, allowing the engine to rev faster and respond more quickly to throttle input. Lightweight flywheels are a popular upgrade for track builds and sport driving applications where improved throttle response matters. Popular Upgrades Top-selling flywheel upgrades include lightweight aluminum flywheels for naturally aspirated four and six cylinder performance builds, single-mass flywheel conversion kits for dual-mass flywheel replacement on diesel trucks, and high-torque steel flywheels for drag racing and clutch upgrades. What is the difference between a single-mass and dual-mass flywheel? A single-mass flywheel is a solid disc that transmits engine torque directly to the clutch. A dual-mass flywheel uses two plates with a spring dampening system to absorb drivetrain vibration, which is common on diesel and direct-injection engines. Single-mass conversions are popular for performance use but may increase cabin NVH. Will a lighter flywheel a...
