DPF/DEF/EGR Delete 2019-2021 6.7L Cummins Dodge Ram 2500/3500 All-in-One EZ LYNK Kit

DPF/DEF/EGR Delete 2019-2021 6.7L Cummins Dodge Ram 2500/3500 All-in-One Kit

Unlock the true performance potential of your 6.7L Cummins with EZ Lynk Tune Package, a fully integrated delete and tuning solution engineered specifically for 2019–2021 Ram 2500/3500 diesel trucks.

This comprehensive performance upgrade permanently removes the most restrictive factory emissions components — DPF (Diesel Particulate Filter), DEF (Diesel Exhaust Fluid) system, and EGR (Exhaust Gas Recirculation) — eliminating costly regenerations, DEF failures, and soot buildup while delivering substantial gains in horsepower, torque, throttle response, and long-term reliability.

By freeing exhaust flow and optimizing ECM calibration, your Cummins runs cooler, stronger, and more efficiently — whether you’re towing heavy loads or building a high-performance street truck.

Please Note!
