BD Diesel Exhaust Manifold Kit for 2011-2026 Dodge Durango, Jeep Grand Cherokee, and Ram 1500 (5.7L)

Fits select 2011-2026 Dodge Durango, Jeep Grand Cherokee, and Ram 1500 (5.7L). Note: This kit does not fit 2019 or later Ram 1500 Classic (DS) body styles.

The BD Diesel Exhaust Manifold Kit (MPN 1041467) provides a permanent solution to the common manifold warping and bolt failure issues found on 5.7L Hemi engines. Unlike factory castings, these manifolds are constructed from heavy-duty high-silicon ductile iron with uniform wall thickness to resist thermal stress and cracking. To ensure long-term reliability, the kit features independent mounting bosses for the heat shield, separating it from the primary mounting bolts to reduce unnecessary strain.

This comprehensive kit includes extended fasteners and spacers specifically engineered to accommodate the thermal expansion of the manifold during heavy engine loads. The bolt mating surfaces are precision-machined to ensure a secure, leak-free joint against the cylinder head.
