This Michigan Motorsports High Inertia Flexplate Kit offers a complete solution for builders, racers, and LS swap enthusiasts looking for a strong, balanced, and race-approved flexplate with the added security of ARP hardware. The included SFI 29.1-certified flexplate is built to withstand the rigors of racing and aggressive street use. Its high inertia design adds extra mass to the drivetrain, helping to stabilize idle, reduce vibration, and store rotational energy for more consistent power through gear changes. To complete the kit, you'll receive 6 ARP 244-2901 flexplate bolts, specifically engineered for LS applications. These fasteners are made from ARP2000 material, known for its superior strength and resistance to stretch, making them a trusted choice for performance and reliability. Together, this kit offers peace of mind and performance in one box — ready for high-power LS builds running automatic GM transmissions.
