Hays Heavy-Duty Flexplates

Product images may differ from actual product appearance.

Hays Heavy-Duty Flexplates are not only engineered to meet the demands of your high-performance or competition engine, but they are also perfect when you want a reliable, quality flexplate for your weekend toy. Don't ruin your project or race season by trusting a thinner factory flexplate that's prone to cracking around the crank bolt holes and hub. Buy a precision built Hays Heavy-Duty Flexplate for your engine's high-torque, high-RPM needs.
