Gator Fasteners Heavy Duty Flexplate Bolt Kit FPBK66

The Gator Fasteners Heavy Duty Flexplate Bolt Kit FPBK66 is engineered to replace factory torque-to-yield flexplate bolts on 6.6L Duramax LB7/LLY/LBZ/LMM/LML/L5P diesel engines with a stronger, reusable fastening solution. Unlike factory bolts that stretch during installation and are not intended for reuse, these heavy-duty bolts are designed to maintain consistent clamping force through repeated service.

Manufactured from Gator Fasteners' proprietary HD220 high-strength material, this kit delivers superior durability and resistance to fatigue under drivetrain load. Rolled threads enhance strength and longevity, while the 12-point head design allows for secure torque application during installation. This kit is suitable for use with both OEM and aftermarket flexplates.

Tech Tip
When installing flexplate bolts, tighten them in stages using the proper torque sequence. Even clamping helps prevent flexplate distortion and ensures long-term reliability.
