Fidanza’s new lightweight aluminum flywheels have less mass than the heavy factory pieces, enhancing engine acceleration, as well as durability. The steel friction surface is made for standard single disc clutches and the steel surface is replaceable too. They say this works well in high-performance handling combinations. 

Official Release:

Fidanza Performance announces the release of their performance lightweight aluminum flywheel #198101 for use on the GM Performance LSX crate engines featuring the OE 8-bolt crank pattern and being mated to a manual transmission.

Like all premium Fidanza aluminum flywheels, this high performance unit is constructed of 6061 T6 aluminum for optimum weight reduction and tensile strength, delivering faster acceleration, quicker throttle response, better vehicle braking, increased clutch efficiency, and long lasting durability. Featuring a precision machined, Rockwell hardened ring gear, along with Fidanza’s signature replaceable steel friction surface, this flywheel is built tough and will never require inconvenient resurfacing or costly replacement when changing out clutches, saving owners both time and money.

Designed to work with LS1 style single disc clutches or standard 10.4” diaphragm clutches, this lightweight flywheel frees up additional horsepower to the wheels and delivers the added adaptability and performance LSX project builders will love!

Features:

• Quicker throttle response
• Hardened ring gear
• Fits standard 8-bolt LS cranks
