2001-2016 Duramax Gator Fasteners HD Rod Bolt Kit (RBK66)

When it comes to building a durable and high-performance 6.6L Duramax engine, the Gator Fasteners Heavy Duty Rod Bolt Kit (RBK66) is a must-have upgrade. Stock rod bolts can become a weak link in high-boost, high-RPM, and heavy-load applications, leading to catastrophic engine failure. Gator Fasteners eliminates this risk by offering an ultra-strong solution designed for extreme durability and performance.

Manufactured from HD220 material, which is significantly stronger than the 8740 material used by competitors, these rod bolts provide superior strength, ensuring they can handle the demands of performance diesel engines. The rolled threads after heat treating enhance fatigue resistance, reducing the chances of thread failure even under extreme stress.

Whether you're pushing your Duramax engine in drag racing, sled pulling, heavy towing, or daily high-performance driving, the RBK66 kit ensures maximum clamping force and reliability. Each kit includes high-quality rod bolts for a direct replacement of the factory bolts.

Upgrade your 6.6L Duramax (LB7, LLY, LBZ, LMM, LML) with Gator Fasteners Heavy Duty Rod Bolts and experience superior strength, longevity, and performance—because "Nothing Bites Like Gator!"
