Luk LFW102 Clutch Flywheel

LuK LFW102 Flywheel Overview

The LuK LFW102 is a clutch flywheel engineered for smooth clutch engagement and a flat, consistent friction surface. It is a direct-fit replacement for a wide range of Chevrolet and GMC trucks, vans, and utility vehicles from 1970-1990.

Built to OE specifications, this new flywheel is a practical alternative to resurfacing when replacing the clutch on applications such as Chevrolet C20, GMC C3500, and Chevrolet Corvette models.

Key Features

• Flywheel diameter: 11.929 in. / 30.3 mm
• Flywheel inner diameter: 16 in. / 6.299 in.
• 168-tooth ring gear for proper starter engagement
• Zero cup depth / step height for the listed application
• New, never remanufactured construction
• Manufactured to OE specifications, including ring gear and dowel pins

Detailed Description

The LuK LFW102 clutch flywheel is designed for vehicles that require a precise mating surface between the engine and clutch assembly. A flywheel with the correct diameter, tooth count, and step height is critical for smooth operation, and this unit is built to match OE requirements for the listed Chevrolet and GMC applications. This part cross-references Sachs NFW1041 for the same application.

Use the LuK LFW102 when servicing classic GM trucks and utility vehicles such as Chevrolet C10, Chevrolet K30, GMC P3500, and Chevrolet P30. The part number LFW102 is also a useful reference when sourcing a replacement flywheel for Chevrolet Corvette and GMC Jimmy applications within the confirmed fitment range.

What It Helps Address

• Uneven or worn clutch contact surface
• Clutch chatter during engagement
• Starter ring gear wear concerns
• Noise or drivability issues related to flywheel condition
• Need for a new flywheel during clutch service instead of resurfacing

Installation Notes and Tips

Confirm flywheel diameter, tooth count, and step height before installation. For Chevrolet C3500 and K3500 applications, refer to LB177 for hard pedal or noise-related issues. Always inspect the clutch assembly, pilot components, and starter engagement surfaces during service. The LFW102 should be installed on the exact vehicle applications listed in the fitment data.

Quality Assurance

LuK manufactures this flywheel to OE specifications as a new component, not a remanufactured part. The design includes OE-matched ring gear and dowel pins for consistent fit and function across the confirmed Chevrolet and GMC applications.
