Gator Fasteners Heavy Duty Up-Pipe Bolt Kit 01-16 GM 6.6L Duramax LB7/LLY/LBZ/LMM/LML

Keep your Duramax exhaust system securely fastened with the Gator Fasteners HD220 Heavy-Duty Up-Pipe Bolt Kit. Up-pipe connections are exposed to extreme exhaust temperatures, vibration, and constant thermal cycling, which can cause factory hardware to weaken and contribute to exhaust leaks. This upgraded bolt kit provides the strength needed to maintain secure connections between the exhaust manifolds, up-pipes, and turbocharger. Whether you're repairing an existing exhaust leak or upgrading your exhaust system, it's a worthwhile improvement for maintaining a reliable, leak-free setup. Manufactured from Gator Fasteners' proprietary HD220 high-strength alloy, these bolts deliver 220,000+ PSI tensile strength, exceeding the strength of standard OEM hardware, 10.9- and 12.9-grade fasteners, and conventional 8740 chromoly. Each bolt features a corrosion-resistant black oxide finish to help protect against rust and harsh exhaust conditions. Precision-machined for dependable fitment, the complete kit includes the hardware needed for both up-pipe-to-exhaust-manifold and up-pipe-to-turbo connections, providing a comprehensive fastening upgrade for your Duramax.
