Bullet Proof Diesel 6700120 Upgraded EGR Cooler for 6.7L Cummins

Upgrade your Ram 2500/3500 with the Bullet Proof Diesel 6700120 EGR cooler — a direct-fit, high-durability replacement engineered for 2010-2024 6.7L Cummins pickup applications (and select 2010-2012 cab-and-chassis models). This cooler addresses the well-known weakness of factory EGR coolers that crack or leak from repeated thermal cycling.

The patented H-Core design uses helically wound stainless-steel tubes instead of rigid straight tubes. The helical construction lets the tubes flex with expansion and contraction, greatly reducing fatigue, heat-stress cracking, and tube-end failures that send coolant into the exhaust. The extra surface area also improves heat transfer. All joints and seams are TIG-welded or vacuum-brazed for added strength.

Key advantages include:

• Stainless-steel tubing far more resistant to thermal shock than OEM units
• Reduced risk of coolant leaks, overheating, and related engine damage
• Direct-fit replacement for common OEM numbers including 68048991AA, 68048988AA, 68444764AA, and 5473092
• Quality-controlled construction for consistent installation
• CARB-compliant (EO D-730-3 / D-730-7)

Gaskets, O-rings, and hardware are not included — reuse existing hardware or purchase a dedicated gasket set. A refundable core charge typically applies. Limited lifetime parts warranty.

Verify your existing cooler style (O-ring connections and clamp configuration) before ordering to ensure exact fitment. This is the upgraded solution built for owners who want the EGR cooler to last rather than become a recurring repair.
