Key Features

• Part number: FW-103

Detailed Description

Pioneer Cables FW-103 is a replacement flywheel for a wide range of Chevrolet and GMC manual transmission vehicles, including Chevrolet C20, K20, P30, and GMC C2500, K3500, and P2500 applications. It is also listed for Chevrolet and GMC vans, Suburban models, and select Blazer and Jimmy applications across the 1968-1989 model years. If you are servicing a Chevrolet C20 flywheel or a GMC P3500 clutch flywheel application, this part number provides the specified tooth count and diameter needed for proper starter engagement and clutch operation.

This part cross-references LuK LFW104 for the same application.

What It Helps Address

• Starter engagement issues caused by worn or incorrect ring gear tooth count
• Clutch chatter related to flywheel runout or imbalance
• Vibration during manual transmission operation
• Replacement needs after flywheel wear, heat checking, or surface damage
• OE-spec restoration on older Chevrolet and GMC drivetrain applications

Installation Notes and Tips

Verify the 168-tooth count and 14.13-inch outside diameter before installation. Confirm whether your application requires a weighted or without-weight flywheel, since several listed vehicles note a without-weight configuration. Inspect the clutch, pilot bearing, and starter condition during service, and have the flywheel surface checked and machined only if needed by a qualified technician.

Quality Assurance

Pioneer Cables manufactures this flywheel as a precision-machined replacement part built to original dimensions and balanced to help remove runout and vibration. The FW-103 is intended for direct replacement use in the listed Chevrolet and GMC manual transmission applications.
