Built to OEM fitment numbers 11518860 and 917-107, the clamp is designed for many GM small‑block and LS-series engines used in Silverado, Sierra, Yukon, Denali, Escalade and Hummer models. The product emphasizes durable materials and precision manufacturing to restore sealing where studs have failed.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this clamp restore a leaking exhaust without removing broken studs?\u003c\/h3\u003e\n\u003cp\u003eThe clamp wraps around the manifold flange and tightens to compress the mating surface against the cylinder head, recreating the seal without chasing or extracting damaged studs.
