ACT Streetlite Flywheel Counterweight Mazda

The ACT Streetlite Flywheel Counterweight (also called a flywheel balance weight or external counterweight) restores correct engine balance when you replace a stock Mazda rotary flywheel with a lighter ACT XACT flywheel. OEM flywheels have the balance weight built in. A lighter aftermarket flywheel needs a separate counterweight to keep the rotating assembly balanced.

Key Features:

• Made for use with ACT XACT Streetlite and ProLite flywheels on Mazda rotary applications
• Keeps the engine's external balance correct for manual-transmission applications after a lightweight flywheel upgrade
• Lets you gain the quicker throttle response and acceleration of a lighter flywheel without giving up engine balance
• Part of ACT's drivetrain line, which is built for both street and race use

ACT XACT flywheels are forged and CNC machined. They are precision balanced, and ACT certifies them to SFI Spec 1.1. The counterweight is the matching component that completes the flywheel upgrade. Choose the child item that matches your application to complete the installation.
