2016-2021 GM / Chevy Duramax LWN 2.8L Parts

What’s Stocked for This Engine

• Full Delete Kit (2016) — Tuner with delete tunes, full EGR removal kit with block-off plates and gaskets, and 3-inch T409 stainless steel Turbo-Back exhaust system with mandrel bends. The 2016 LWN Duramax delete kit has its own ECM calibration that doesn’t carry over to 2017+ trucks. Fits Chevy Colorado and GMC Canyon only.
• Full Delete Kit (2017–2021) — Advanced performance tuner with delete support pack and 4 tuning credits, 3-inch T409 stainless steel Turbo-Back exhaust with adjustable resonance control, and EGR removal kit included. This is the 2.8 LWN Duramax kit for later-model Colorado and Canyon vehicles — won’t fit 2016.
• EGR Delete Kit — EGR block-off plates, gaskets, and mounting hardware for the 2016–2019 2.8L Duramax LWN. A simpler block-off system than what you’d see on a 6.6L because the inline-4 cylinder head and cooler geometry are different. Worth noting: physical EGR install on the LWN is tight — many truck owners choose to electronically disable the EGR via the tune instead. Standalone part for customers who don’t need the full kit.
• ECU Unlock Tool — Standalone ECU unlock device covering 2016–2020 Colorado/Canyon 2.8L Duramax. Unlocks the factory ECM so custom delete calibrations can be loaded — it doesn’t include a tuner itself. This is the component you need if you already have an exhaust system and just want to add DPF, DEF, and EGR delete tuning for more horsepower and efficiency. Worth a review of the Duramax engine’s connecting rods limits before pushing past +90HP — the LWN factory internals aren’t built for heavy power gains.
• 3-Inch Turbo-Back Exhaust — Stainless steel 3-inch Turbo-Back Exhaust for 2016–2020 Canyon/Colorado LWN Duramax. Mandrel-bent with pre-welded contour hangers, stronger flanges, and clamps. Replaces the factory exhaust from the turbo outlet back — removes the diesel particulate filter and catalytic converter section. Standalone product for off-road and race use. No 4-inch or 5-inch options exist for this platform — 3-inch is the only brand of Turbo-Back built for the LWN diesel engine.

Key Features and Benefits of the 2.8 LWN Duramax Delete Kit

• No more DPF clogging or incomplete regen cycles
• Cleaner intake without EGR cooler soot buildup
• DEF system eliminated — no refills or injector faults
• Better tow performance from reduced exhaust backpressure
