About This Product

Experience unparalleled performance and durability with our enhanced RAM truck exhaust manifolds, specifically designed for 6.4L 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.

Why do my stock 6.4L HEMI manifold bolts keep breaking?

The factory exhaust manifolds on 2014-2024 Ram 6.4L HEMI engines are prone to warping from high heat. This distortion puts extreme stress on the mounting bolts, causing them to stretch and eventually snap, which is the root cause of the failure. — This is a common failure on Ram 2500, 3500, 4500, and 5500 trucks, especially those used for towing or commercial applications that generate high exhaust gas temperatures (EGTs). The original equipment design cannot adequately handle the thermal expansion, leading to repeated failures. The BD Diesel kit (1041454) permanently corrects this by using high-silicon ductile iron that resists warping, plus a unique fastening system with longer bolts and spacers. This design allows the manifold to expand and contract without binding, eliminating the stress that causes bolt failure.

What makes this BD manifold kit better than just buying another stock one?

This is a permanent engineering solution, not just a like-for-like replacement. The BD Diesel manifolds are made from superior materials and feature a redesigned fastening system to eliminate the factory design flaw. Installing another set of OEM manifolds will likely lead to the same failure down the road. — The BD kit provides a comprehensive upgrade over the stock parts: — • Material: They are cast from high-silicon ductile iron, which has significantly better resistance to heat warp and cracking compared to the standard grey iron of the OEM manifolds. • Thick-Wall Design: The manifold castings feature thick, uniform walls to dissipate heat evenly and prevent the localized stress points that lead to cracking. • Strain-Reducing Fasteners: The kit includes specialized longer bolts and spacers that allow the manifold to expand and contract independently, preventing the stress that snaps bolts. • Independent Heat Shield Mounts: BD added a separate mounting boss for the heat shield, isolating it from the main manifold fasteners to further reduce stress.

Will this kit fit my 2019 Ram 3500 with the 6.4L engine?

Yes, this exhaust manifold kit is a direct fit for all 2014-2024 Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.4L HEMI engine. — The kit is engineered as a bolt-on replacement for the specified model years. The full kit (part #1041454) includes both the driver's side manifold (part #1041456) and the passenger's side manifold (part #1041464). All mounting surfaces are CNC machined to ensure a perfect, leak-free seal against the cylinder head. The kit connects to the stock exhaust system without requiring any welding or custom fabrication.

What exactly comes in the full exhaust manifold kit?

The full kit, part number 1041454, is a complete bolt-on package that includes both the driver's side and passenger's side exhaust manifolds. It also contains a full set of new high-grade gaskets, bolts, spacers, and nuts required for installation. — This is a comprehensive kit designed to provide everything a technician needs for the job. Inside the box you will find: — • One Driver's Side High-Silicon Ductile Iron Manifold (1041456) • One Passenger's Side High-Silicon Ductile Iron Manifold (1041464) • A complete set of specialized longer mounting bolts and spacers • All required manifold-to-head gaskets for a secure seal • All necessary studs and nuts for a complete hardware refresh.

How long does this kit take to install and are any special tools needed?

The estimated installation time is approximately 4 hours and 48 minutes for a professional. The most common difficulty is removing the old, broken factory manifold bolts, which may require a bolt extraction kit. — While this is a direct-fit kit, the condition of the factory hardware is the biggest variable. It is highly recommended to have a set of high-quality bolt extractors (easy-outs), a right-angle drill, and plenty of penetrating oil on hand before you begin. The BD kit itself assembles with standard metric hand tools. The new hardware and gaskets are all included, so no additional parts are needed once the old manifolds and any broken bolts are successfully removed from the cylinder heads.
