BD Diesel 1046068 Exhaust Manifold Kit for 2013-2018 RAM 3500/4500/5500 6.7L

Vehicle Fitment

• 2013-2018 RAM 3500 Cab & Chassis (All Trims, 6.7L Cummins)
• 2013-2018 RAM 4500 Cab & Chassis (All Trims, 6.7L Cummins)
• 2013-2018 RAM 5500 Cab & Chassis (All Trims, 6.7L Cummins)

Fitment Notes

• Designed specifically for 6.7L Cummins diesel engines in RAM cab-chassis heavy duty trucks.
• Direct-fit exhaust manifold replacement - mounts to factory exhaust ports and turbo flange.
• Not CARB legal in certain states (not for sale in California) due to emissions hardware regulations.

Features

• Fully divided pulse exhaust manifold engineered for strength and thermal expansion control
• Cast from high-silicon ductile iron for resistance to extreme temperature cycling and vibration
• Precision slip joints allow expansion and contraction to reduce cyclic thermal fatigue
• Thick-walled construction helps prevent cracking and exhaust leaks over extended use
• Includes EGR port, exhaust port, and turbo mount gaskets for complete installation
• Comes with grade 10.9 hardware including bolts and spacers for durable mounting
• Pre-drilled manifold ports allow for optional pyrometer probe installation
• Replaces the original factory manifold for improved longevity in demanding diesel service

Product Description

The BD Diesel 1046068 Exhaust Manifold Kit is a direct replacement exhaust manifold engineered for 2013-2018 RAM 3500, 4500, and 5500 Cab & Chassis heavy duty trucks equipped with the Cummins 6.7L diesel engine. This kit's fully divided pulse manifold design is cast from high-silicon ductile iron, able to withstand the intense heat and vibration produced during diesel operation. Precision slip joints accommodate thermal expansion and contraction, reducing the risk of fatigue cracking that can occur with prolonged exhaust heat cycles.

This exhaust manifold kit includes all necessary gaskets, turbo mount seals, bolts, and spacers required for a complete installation. Its durable construction and engineered reinforcement points help provide reliable service life in both daily use and severe duty applications. Pre-drilled ports allow optional installation of pyrometer probes for temperature monitoring. Whether used to replace a cracked or leaking stock manifold or as part of heavy duty engine work, this BD Diesel kit offers a robust upgrade for Cummins diesel exhaust performance and longevity.
