BD Diesel USA is a performance-oriented company specializing in high-quality diesel and heavy-duty truck components and upgrades. Their products are engineered to handle high pressure, high temperature, high load, and extended operation, not just occasional use. With years in the field (including intensive hours of idling, towing, and heavy usage), the BD Diesel's engineering and R&D is informed by real use cases.
Heavy walled Manifolds for improved durability. Manifolds are coated to resist corrosion and are pre-drilled for pyrometer probes. These units replace the old rusted and leaking stock exhaust Manifolds that normally require extensive cleaning and machine work to be recovered from warping and distortion.
The Manifold set comes with both passenger and driver's side units and feed pipe mounting hardware. With the stock Manifolds considered a maintenance item due to corrosion and leaking, this set is an excellent preventative replacement item whenever doing other engine work.
