US Diesel Parts - BD Diesel - 03-07 Dodge 5.9L

The 2 and 3 piece manifold design that BD offers for the 2003 to 2007 Common Rail 5.9L Cummins diesel are far superior to the factory manifold. The original single piece manifold was prone to cracking right near the center due to the expansion and contraction from heat cycles of the engine block. The slip joint design alleviates stress by allowing the manifold to slip wider as the engine comes to temperature and then, once over 100° F, seals tight again for a leak free solution.
