Mopar 8 Bolt Steel Flywheel 143 Tooth

The Mopar 8 Bolt Steel Flywheel 143 Tooth is a heavy-duty clutch component engineered for Mopar-platform vehicles requiring reliable power transmission and consistent engagement characteristics. Designed for operators who demand bulletproof drivetrain dependability, this steel flywheel serves as the foundation for any serious clutch system upgrade. Whether you're building a performance platform or restoring a classic muscle car, the proper flywheel selection is non-negotiable—it directly impacts shift quality, drivability, and longevity of your entire clutch assembly.

RAM CLUTCH's 143-tooth configuration matches OEM Mopar specifications while the steel construction delivers superior heat dissipation and durability compared to cast-iron alternatives. At 37 pounds, the flywheel maintains proper rotational inertia without excessive rotating mass that can compromise throttle response or fuel economy. The 8-bolt mounting pattern integrates directly with Mopar crankshafts, ensuring precise alignment and vibration control. Steel construction resists stress cracks and thermal distortion that occur under aggressive driving, high-load towing, or repeated engagement cycles—critical for both street and off-road applications.

This flywheel is essential for anyone upgrading clutch systems on Mopar V8 and high-displacement applications where OEM components may not meet current performance demands. Technicians and enthusiasts working on Dodge, Plymouth, and Chrysler platforms with 8-bolt crankshaft patterns will find this unit a direct bolt-on replacement. Proper installation requires engine disassembly and balance verification with your chosen clutch disc; many shops recommend resurfacing the friction surface to factory specifications before assembly. Compatible with RAM CLUTCH pressure plates and performance friction materials for seamless system integration.
