Flexplate Bolt Kit GM 6.6L Duramax Diesel

The Flexplate Bolt Kit GM 6.6L Duramax Diesel by ARP is designed for builders and mechanics who require high reliability in high-torque engine applications. This kit is essential for securing the flexplate, which connects the engine to the transmission, especially in the 6.6L Duramax diesel known for its substantial rotational forces.

Manufactured from premium alloy steel, ARP bolts provide superior tensile strength compared to OEM hardware, ensuring consistent preload across all fastening points. The engineering of this kit addresses flexplate runout and concentricity issues by maintaining uniform bolt tension, which reduces stress concentration and prevents micromovements that can lead to bolt shear or cracking.

Diesel enthusiasts who are upgrading to larger turbochargers, higher fuel injection pressures, or making transmission modifications will find significant benefits from this kit, as it ensures greater preload reliability under increased power demands. Installation is straightforward for experienced mechanics, making it a practical choice for both stock and modified Duramax engines.
