- 2013–2018 6.7L Ram Cummins 3500 Cab & Chassis trucks diesel engine.
DESCRIPTION
Product Overview
-
Factory 2013–2018 Ram 3500 Cab & Chassis 6.7L Cummins trucks are designed for heavy-duty operation but can experience exhaust restriction and EGR-related issues from the factory emissions system. The OEM DPF/CAT assembly adds exhaust restriction, while the EGR system recirculates soot back into the intake, contributing to carbon buildup and reduced airflow efficiency.
- The Cummins Cab & Chassis Package addresses these common restrictions with a high-flow 4" exhaust pipe and complete EGR delete components. Designed specifically for commercial chassis applications, this kit helps improve exhaust flow, reduce soot contamination, and provide a cleaner, more reliable engine setup for heavy-duty use.
Key Features
-
DPF/CAT Race Pipe: Eliminates the restrictive OEM DPF and Cat to drastically reduce exhaust backpressure, speed up turbo spool, and drop towing EGTs.
- EGR Cooler Removal: Removes the OEM EGR cooler assembly, stopping soot recirculation and removing internal coolant leak risks on heavy-duty work trucks.
- Stops Regeneration Fuel Consumption: Eliminates fuel-wasting active DPF regeneration cycles during long idle times or heavy commercial hauling.
- Cab & Chassis Exclusive Fitment: Designed specifically to clear commercial frame rails, DEF tanks, and rear axle configurations without hitting or rubbing.
FAQ
Q: What are the included metal brackets and long studs used for?
A: When the bulky factory EGR cooler is unbolted, the engine wire harness and transmission dipstick lose their stock mounting points. The included bracket and studs securely re-anchor them in place to prevent rattling and wire chafing.
Q: Why do I need a Cab & Chassis specific kit instead of a regular RAM Pickup kit?
A: Commercial 3500/4500/5500 Cab & Chassis trucks feature flatter frame rails, different crossmembers, and larger EGR manifold ports. Regular pickup bed delete pipes and smaller EGR plates will not fit and will cause severe exhaust leaks.
Q: Do I need to completely remove the OEM EGR cooler when installing this kit?
A: Yes. This is a complete EGR cooler delete package. The factory EGR cooler assembly must be removed before installing the included Cab & Chassis block-off plates, coolant bypass components, and mounting brackets for proper fitment.
Q: Is custom ECM delete tuning required when installing this complete 4" delete kit?
A: Yes,Deleting the DPF and EGR hardware will immediately trigger Check Engine Lights (CEL) and put the truck into "limp mode" unless custom ECM delete software (Minimaxx tuner V2) is flashed prior to starting the engine.
