Thumbnail Filmstrip of 2010-2022 6.7L Cummins EGR Cooler Bullet Proof Diesel 6700120 Images
Videos (1)
A cracked factory EGR cooler on a 6.7 Cummins dumps coolant straight into the exhaust. Replace that rigid cooler with Bullet Proof Diesel 6700120, an aftermarket pickup cooler built with helically wound stainless tubes that flex through heat cycles instead of splitting. Upgrade it before the next split turns a short drive into a tow.
- Build: Helically wound stainless tubes, TIG welded or vacuum brazed, so the core can move with heat instead of cracking the way rigid factory tubes do.
- Part numbers: Manufacturer part Bullet Proof Diesel 6700120. It crosses to Ram 68048991AA, 68048988AA, 68444764AA, and 5473092, so a pasted OEM number still matches this cooler.
- Fits: 2010-2024 Ram 2500 and 3500 pickups with the 6.7L Cummins, the truck coolers Bullet Proof lists for those years. This store also lists 2010-2012 cab and chassis. Confirm that chassis against the cooler on the truck before you order.
- Does not fit: Not the 6700123 hose-clamp cab and chassis cooler, and not 6700125 or 6700126.
- Not in the box: Gaskets are not included. Reuse sound factory gaskets or add gasket set 90100100 so the flanges seal on the first install.
- Emissions: CARB Executive Order D-730-3 covers 2010-2018 Dodge and Ram 2500/3500 pickups. D-730-7 covers 2018-2024 Ram 2500/3500.
A refundable core charge is added at checkout and refunded when your old cooler is returned per our core terms.
