FITMENT
- 2013–2019 6.7L RAM Cummins 3500 Cab & Chassis.
- 2013–2019 6.7L RAM Cummins 4500 Cab & Chassis.
- 2013–2019 6.7L RAM Cummins 5500 Cab & Chassis .
- Does NOT fit regular Pickup Bed RAM 2500/3500 models due to completely different frame rail geometry, crossmembers, and pipe routing.
DESCRIPTION
Product Overview
-
The 2013–2019 Ram 3500/4500/5500 6.7L Cummins Cab & Chassis suffers from fuel-wasting DPF regenerations, fail-prone DEF sensors triggering 55 MPH limp modes, and leaking EGR coolers that spike engine heat and risk head gasket failure under heavy commercial towing.
- The Ram Cab & Chassis 4" DP-Back Delete Kit with Mini Maxx V2 Tuner fixes these issues completely. The pre-loaded tuner clears CEL codes and disables emissions diagnostics, while the 4" race pipe and EGR bypass lower EGTs, stop carbon sludge, eliminate backpressure, and restore total fleet reliability.
Key Features
-
Shift-on-the-Fly Power Gains: Instantly change power settings while driving, unlocking up to 150+ additional horsepower and boosting commercial fuel efficiency.
- Prevents Commercial Fleet Downtime: EGR cooler bypass stops hot soot recirculation, protecting coolant systems and preventing head gasket failure under severe loads.
- Cab & Chassis Exclusive Fitment: Precision-engineered specifically for 2013–2018 Ram 3500, 4500, and 5500 Cab & Chassis flatbed/commercial frame rails.
- Pre-Loaded Race Tuner: Automatically clears check engine lights (CEL) and permanently disables DPF regenerations, DEF 55 MPH speed limiters, and EGR diagnostics.
FAQ
Q: Why is this kit specifically labeled for Cab & Chassis models instead of regular pickup trucks?
A: Ram Cab & Chassis trucks use flat frame rails, longer wheelbases, custom rear axle clearances, and commercial ECM software compared to standard pickups. This kit includes matching 4" exhaust geometry and Cab & Chassis-specific tuning.
Q: Will the included tuner clear DEF fault codes and bring my commercial truck out of speed-limited limp mode?
A: Yes. The pre-loaded Cab & Chassis delete software automatically turns off diagnostic trouble codes (CEL) for DEF level sensors, fluid heaters, NOx sensors, and DPF differential pressure switches, clearing speed limiters instantly.
Q: Does installing a 4" downpipe-back exhaust system require removing the factory turbo downpipe?
A: No. A downpipe-back system connects directly to the exit flange of your stock turbo downpipe, replacing the middle DPF and rear SCR filter sections. This speeds up installation while preserving your factory turbo clamp connection.
Q: Can I change power levels on-the-fly while driving with the included tuner?
A: Yes. Shift-on-the-Fly (SOTF) lets you switch power levels—Stock (+0 HP), Tow (+50 HP), Street (+100 HP), and Performance (+150+ HP)—while driving using a multi-position switch connected to your engine or tuner harness.
