DogBone by UnderDog Diesel – Flexplate Bolt Kit

The factory flexplate bolts are torque-to-yield and must be replaced any time they are loosened or removed. Increased engine torque can cause these OEM bolts to stretch or fail, leading to vibration, noise, or even transmission issues.

DogBone’s Flexplate Bolts are engineered from premium chrome-moly alloy and are specifically designed to handle the demands of high-performance and heavy-duty diesel applications. With a yield strength over 215,000 psi and tensile strength exceeding 230,000 psi, these bolts deliver unmatched durability and clamping force.

Perfect for both engine rebuilds and performance builds, DogBone Flexplate Bolts provide superior fastening integrity for both factory and aftermarket flexplates, ensuring long-term reliability under extreme torque conditions.

Note: Not compatible with manual transmission flywheels.
