4G 6.7L Cummins T4i Manifold Hardware & Gasket Upgrade Kit | 2007.5–2018 Ram
The Diesel Power Source® 4G 6.7L Cummins T4i Manifold Hardware & Gasket Upgrade Kit is a complete add-on package designed to fully install the DPS T4i 6.7L Cummins Exhaust Manifold (MAN0140) on 2007.5–2018 Dodge Ram 2500 and 3500 pickup trucks. It includes every gasket and fastener needed for the manifold-to-head install, the T4i turbo flange install, and the EGR cooler mounting — sourced together so you don't have to chase parts mid-build.
This kit replaces the standard flange bolts found in the manifold's base hardware kit with a full stud-and-nut configuration, the preferred mounting method for high-EGT applications. Multi-Layer Steel (MLS) gaskets resist burnout, blow-through, and warping far better than single-layer alternatives, and the T4i non-divided turbo flange gasket and oil drain gasket are included to complete the install.
Designed as the recommended upgrade to the DPS 4G T4i 6.7L Cummins Exhaust Manifold (MAN0140). The base kit included with the manifold ships with standard flange bolts. This upgrade adds the gaskets, stud-and-nut hardware, and the additional fasteners needed for both the turbo and EGR cooler mounting in one purchase.
Why Upgrade From the Base Hardware Kit
The base hardware kit shipped with the MAN0140 manifold gets the manifold mounted to the head — but it doesn't include MLS gaskets, turbo flange hardware, or the EGR cooler mounting fasteners required for a full install. This upgrade kit adds all of those components in a single SKU.
Stud-and-Nut Manifold Mounting
Studs provide more consistent clamping load than bolts and resist fastener fatigue from repeated thermal cycling — critical for an exhaust manifold that sees hundreds of heat cycles a year. Studs also make future manifold removal far easier; you back off nuts instead of breaking loose corroded bolt threads in the head.
Multi-Layer Steel Gaskets
MLS gaskets use stacked stainless layers to seal the variable surfaces between the manifold and head. They handle higher boost, higher EGTs, and more aggressive tuning than single-layer gaskets without burning through or warping.
T4i Non-Divided Turbo Flange Gasket Included
The DPS 4G T4i manifold uses a non-divided pulse design that matches the factory HE351VE and HE300VG turbo flange. The correct T4i gasket is included along with the turbo oil drain gasket — no separate sourcing required.
Includes EGR Cooler Mounting Hardware
The 6.7L Cummins manifold mates to the EGR cooler at the rear of the manifold. This kit includes the additional 4 studs and 4 nuts needed to mount the EGR cooler back to the manifold during install, alongside the 4 studs and 4 nuts for the T4i turbo flange.
Who This Kit Is For
- Owners of 2007.5–2018 Dodge Ram 2500 and 3500 pickup trucks running the 6.7L Cummins
- 4G Cummins builders installing the DPS T4i 6.7L Exhaust Manifold (MAN0140)
- Trucks keeping the factory HE351VE (2007.5–2012) or HE300VG (2013–2018) turbocharger
- EGR-intact builds requiring the EGR cooler to be remounted after manifold replacement
- Tow, daily driver, and stock-flange performance builds
- Builders who want all install hardware and gaskets in a single purchase

Frequently Asked Questions
Not strictly. The base hardware kit shipped with the manifold has the bolts needed to mount it to the head. This upgrade kit is for builders who also want MLS gaskets, a stud-and-nut manifold mount, and the additional hardware required to install the turbo and re-mount the EGR cooler.
Yes. The T4i flange and gasket in this kit fit both the factory HE351VE (2007.5–2012) and HE300VG (2013–2018) turbochargers. Both use the same T4i flange pattern.
The 8 studs are split between two functions — 4 for the T4i turbo flange and 4 for the EGR cooler that mounts to the rear of the manifold. The kit covers both attachment points so you don't need separate hardware for each.
No. This kit fits the DPS 4G T4i pickup-truck manifold only. Cab & Chassis trucks (Ram 3500/4500/5500 Cab & Chassis) use a different manifold-to-exhaust routing that the MAN0140 manifold isn't designed for.
Yes. The 12 manifold studs and nuts directly replace the bolts in the base hardware kit. No machining or modifications required.
