Description
The BD Diesel Exhaust Manifold Kit is a heavy-duty replacement solution designed to correct the common cracking, warping, and bolt failure issues found in factory GM exhaust manifolds. Built for durability and long-term reliability, this kit is ideal for stock or mildly modified Silverado and Sierra 1500 V8 trucks.
Manufactured from high-silicon ductile iron with increased wall thickness, these manifolds are engineered to handle extreme heat cycles while reducing stress and distortion. BD Diesel’s upgraded hardware and mounting design improves clamping force and allows controlled expansion, helping prevent future leaks and broken bolts.
