BD Diesel Exhaust Manifold Kit

The BD Diesel Exhaust Manifold Kit line offers heavy-duty replacement and upgrade exhaust manifolds for gas and diesel trucks. Factory manifolds can crack, warp or break bolts after repeated heat cycling. These kits are engineered to prevent that, so you get a more durable exhaust connection and a lasting fix for exhaust leaks and manifold bolt failures.

Key Features:

• Durable cast construction: Thicker cast-iron or high-silicon ductile iron castings resist cracking and warping.
• Even wall thickness: BD uses CAD and FEA simulation to reduce stress points in the casting as temperatures change.
• Improved fastener design: Longer bolts and added spacers give the fasteners room to handle thermal expansion.
• Machined mounting surfaces: The bolt-mating surfaces are machined so the manifolds seat securely against the cylinder heads.
• Heat shield provisions: Depending on the application, the kits have separate heat shield mounts or bosses that keep the factory heat shields in use.
• Installation hardware: The kits include new gaskets and fasteners for installation.

BD Diesel is known for diesel and truck performance and durability parts. Each kit in this line is built as a stronger alternative to the factory manifold, for trucks that are worked hard, whether towing, hauling or daily driving. Select the child item that matches your application.
