Bullet Proof Diesel 6700126 EGR Cooler with Straight Flange for 6.7L Cummins
Replace a failing factory EGR cooler with a purpose-built upgrade designed to survive the heat cycles that destroy OEM units. The Bullet Proof Diesel 6700126 features patented H-Core technology with helically wound stainless-steel tubing that flexes under thermal stress instead of cracking. This construction significantly reduces fatigue and heat-stress failure while allowing more tubing for improved cooling of recirculated exhaust gases.
All joints and seams are TIG-welded or vacuum-brazed for strength. Every unit is quality-checked for a direct-fit installation on the intended applications.
Key Features
- Patented H-Core helical stainless-steel tubing resists cracking from repeated heating and cooling
- TIG-welded or vacuum-brazed construction throughout
- Direct-fit replacement with consistent quality control
- Limited lifetime parts-only warranty
- CARB Executive Order D-730-7
Fitment Designed for 2017–2021 Ram 3500/4500/5500 Cab & Chassis trucks with the 6.7L Cummins ISB engine and a straight exhaust flange. Also used on corresponding Cummins 6.7L ISB and Paccar PX-7 applications. Confirm your existing cooler has a straight (not angled) flange before ordering; the angled-flange version is a different part.
Common OEM replacements include 5341879, 5443691, 5405854, 5529387, 5566897, and 68444084AA (verify your specific number).
Important Notes Gaskets and hardware are not included. A gasket set is required for installation. This cooler is intended for vehicles with a straight flange only.
