Product Details

The ATP Parts Z-291 flywheel provides the mounting surface for the clutch assembly and the tooth ring needed for starter operation. On manual transmission vehicles, the flywheel must maintain a consistent friction surface so the clutch disk can engage smoothly. This replacement flywheel is specified with 142 teeth and a 12.0" outside diameter, making it the correct choice for a wide range of GM and Isuzu applications, including Chevrolet Cavalier, Pontiac Sunfire, and GMC Sonoma models listed in the fitment data. ATP Parts Z-291 is intended to restore proper drivability when the original flywheel is cracked, damaged, or has worn starter teeth.

This part cross-references LuK (e.g., LFW162) for the same application.

What It Helps Fix

• Cracked or broken flywheel surfaces
• Worn or damaged starter teeth
• Clutch chatter caused by an uneven friction surface
• Poor clutch engagement on manual transmission vehicles
• Noise or starting issues related to flywheel wear

Installation Notes and Tips

Verify tooth count, outside diameter, and clutch cover clearance before installation. Confirm the vehicle uses the listed 142-tooth, 12.0" flywheel configuration, especially on Chevrolet Cavalier, Pontiac Sunfire, and GMC Sonoma applications. Inspect the clutch assembly, starter, and related wear components during service so the replacement flywheel can operate against clean, even mating surfaces.
