BD Diesel Passenger Side Exhaust Manifold - 02-13 Chevy Silverado 1500 & GMC Sierra 1500 V8

This kit gives you a new passenger side exhaust manifold, designed to replace the original on many GM trucks with LS-based V8 engines from 2002 to 2013. It also includes all the necessary hardware for installation: longer bolts, spacers, and new gaskets. This setup is built to handle the common issue of exhaust manifold bolt failures, which often happen due to the stress from thermal expansion and contraction over time.

BD Diesel has beefed up this manifold with a thicker wall design made from high-silicon ductile iron, which helps prevent warping and cracking. They've also adjusted the mounting points for the heat shield and used longer bolts along with added spacers. These longer fasteners and spacers work to reduce the stress on the bolts themselves, helping to prevent them from breaking or loosening up, which is a frequent problem with stock manifolds. The machined mating surfaces ensure a solid seal when you bolt it up.

This manifold is a direct replacement for GM OEM part numbers 12616286 and 12677665. While it's designed to fit a wide range of GM trucks and SUVs, including popular models like the Chevrolet Silverado and GMC Sierra, it's always a good idea to double-check the fitment for your specific vehicle.
