Bullet Proof Diesel 6700125 6.7 Cummins EGR Cooler

Upgrade your 6.7L Cummins with a durable, long-life EGR cooler built to handle the heat cycles and thermal stress that cause factory units to crack and fail. The Bullet Proof Diesel 6700125 uses patented H-Core technology with helically wound stainless-steel internal tubing. This flexible design lets the tubes expand and contract instead of rupturing, greatly reducing or eliminating fatigue and heat-stress failures common in conventional coolers.

All joints and seams are TIG welded or vacuum brazed for added strength. The unit is quality-controlled for a precise, direct-fit replacement. Stainless-steel construction improves corrosion resistance and overall durability, making this cooler a strong choice for heavy-duty work.

Fitment Designed for 6.7L Cummins ISB applications (2011–2018) and compatible Paccar PX-7 engines. Widely used on 2013–2022 Ram 3500, 4500, and 5500 Cab & Chassis models with the 6.7L Cummins. This version is for the angled exhaust flange configuration. Confirm your existing cooler (flange style and mounting) before ordering.
