Thumbnail Filmstrip of LB7|LLY Duramax Heavy Duty Main Stud Kit Gator Fasteners MSK667Y Images
Secure the foundation of your 2001-2004 GM 6.6L Duramax LB7/LLY with the Gator Fasteners MSK667Y Heavy Duty Main Stud Kit. This kit is the ultimate upgrade for any engine build, from a dedicated race engine to a reliable tow rig or a durable daily driver. Unlike the factory bolts, which are prone to stretching under stress, these high-strength main studs are engineered to deliver a superior clamping force. This prevents the main caps from shifting or "walking," a common cause of catastrophic engine failure in high-performance applications.
- Main Studs: Engineered for ultimate strength and durability.
- Increased Strength: Significantly boosts the bottom end's structural integrity.
- Increased Durability: Ensures your engine can handle the demands of any performance upgrade.
- Quality Manufacturing: Produced in an ISO/TS 16949 Quality Control Factory, ensuring strict quality and performance standards.
For a professional-grade installation, we highly recommend using thread cleaning chasers (sold separately). Properly cleaned threads in your engine block are crucial for achieving accurate torque readings and a secure, long-lasting fit. Backed by a 5-Year Limited Manufacturer Warranty, the Gator Fasteners MSK667Y kit provides the confidence and security you need for your Duramax build
