About This Product

Experience unparalleled performance and durability with our enhanced Dodge/RAM truck exhaust manifolds, specifically designed for 5.7L HEMI engines. Our BD upgraded manifolds address common exhaust manifold bolt failures by incorporating extended fasteners and spacers that effectively withstand thermal expansion. In addition, we've engineered independent mounting locations for the heat shield, separating it from the mounting bolts to further enhance reliability. Crafted with precision, our BD Manifolds boast a robust, thicker design, and are constructed from high-silicon ductile iron to combat warping, ensuring your vehicle remains at peak performance for the long haul.

What problem does this manifold solve that the stock one doesn't?

This is a heavy-duty replacement for the factory Ram Hemi exhaust manifold, engineered to permanently fix the common issue of broken manifold bolts and subsequent exhaust leaks, often identified by a distinct "Hemi tick" noise. — The original equipment (OE) manifolds on 5.7L and 6.4L Hemi engines are known to warp from thermal cycling. This distortion places extreme stress on the mounting studs, causing them to break and create an exhaust leak. The BD Diesel manifold kit corrects this design flaw using a thicker, more robust casting made from high-silicon ductile iron, which resists warping and dissipates heat more effectively. The included hardware is also upgraded to longer fasteners with spacers, a system designed to accommodate thermal expansion without fatiguing and snapping the bolts.

Does this kit fit both 5.7L and 6.4L Hemi engines?

Yes, this exhaust manifold kit is designed for a wide range of Ram trucks equipped with either the 5.7L or 6.4L Hemi engine. It fits most 1500, 2500, 3500, 4500, and 5500 models from the 2009 model year forward. — This kit offers broad compatibility across the Ram truck lineup. It is specifically confirmed to fit: — • Ram 1500 "Classic" (DS body style) from 2009-2024 • Ram 2500, 3500, 4500, & 5500 trucks from 2009-2026 This specific product page is for the passenger side kit, part number 1041464. BD Diesel also offers the driver's side as part number 1041465, or you can purchase a complete kit with both manifolds under part number 1041463.

What's included in this kit besides the manifold itself?

The kit is comprehensive and includes all the necessary specialty hardware required for a complete installation. Along with the manifold, it provides new gaskets, longer mounting bolts, and spacers so you don't need to source parts separately. — The goal is a one-box solution to the common Hemi exhaust leak. Inside the box for passenger side kit 1041464, you will find: — • The heavy-duty, high-silicon ductile iron exhaust manifold. • A new manifold-to-cylinder head gasket. • A full set of upgraded, longer Grade 8.8 fasteners. • A set of precision-machined spacers that work with the longer bolts to absorb thermal expansion.

How exactly does this design prevent the manifold bolts from breaking?

This manifold system prevents bolt failure by addressing the two root causes: manifold warping and fastener stress. It uses a more dimensionally stable manifold and an improved fastening system that properly manages thermal expansion. — The BD Diesel solution is a two-part engineering fix. First, the manifold itself is cast from high-silicon ductile iron with much thicker, uniform walls, making it significantly more resistant to warping than the OEM part. Second, the kit replaces the original torque-to-yield studs with longer, higher-quality bolts and standalone spacers. This design allows the manifold to grow and shrink with heat cycles without putting the same direct shear and tensile stress on the fasteners, which is the primary cause of fatigue and breakage in the factory setup.

How difficult is the installation and are any special tools needed?

The estimated installation time is 4.5 hours for one side, but this can vary. While the job uses standard mechanic's tools, you will likely need a stud extractor set, as broken factory bolts are common with this repair. — While this is a direct, bolt-on replacement, the difficulty is often determined by the condition of the hardware being removed. Accessing the bolts can be tight, and it is almost guaranteed that one or more of the factory studs will be broken off in the cylinder head. We strongly advise soaking the old nuts and bolts in a quality penetrating oil for several hours or overnight before attempting removal. If studs are broken flush, you will need to carefully drill them out and use an extractor bit, which adds significant time to the 4.5-hour baseline estimate.

Can I buy just the passenger side manifold or do I have to get the pair?

Yes, you can purchase the passenger side manifold kit by itself. This product, part number 1041464, is for the passenger (right) side only. — BD Diesel offers flexible options to suit your specific repair needs. While it's often a good idea to replace both manifolds at the same time, you are not required to. The individual part numbers are: — • PN 1041464: Passenger Side Kit (manifold, gasket, bolts, spacers) • PN 1041465: Driver Side Kit (manifold, gasket, bolts, spacers) • PN 1041463: Complete Kit with both driver and passenger side manifolds and hardware.
