Luk LFW131 Clutch Flywheel

OE-Style Flywheel for Manual Transmission Service

The LuK LFW131 clutch flywheel is built for manual transmission clutch replacement on a wide range of classic Chevrolet, Pontiac, Buick, Oldsmobile, and GMC applications. With a 153-tooth ring gear and OE-spec engineering, it provides the smooth, flat friction surface needed for consistent clutch engagement.

Detailed Description

LuK LFW131 is a replacement clutch flywheel designed to restore the mating surface required for proper clutch operation. Because the flywheel is a critical part of the clutch system, replacing it during clutch service helps ensure the new clutch set seats against a flat, uniform surface. This flywheel is a practical alternative to resurfacing when the existing unit is worn, heat-checked, or out of spec.

This part cross-references Sachs NFW1017 for the same application. It is also listed with fitment across Chevrolet Camaro, Chevrolet Corvette, and Pontiac Firebird applications, along with additional classic GM models that use the 153-tooth configuration.

What It Helps Solve

• Clutch chatter caused by an uneven flywheel surface
• Judder or grab during clutch engagement
• Heat spots, scoring, or glazing on the existing flywheel
• Repeat clutch wear from an out-of-spec mating surface
• Service delays when resurfacing is not the preferred option
