Introduction

The 6.6L Duramax LML EGR Delete Kit removes the factory EGR valve and cooler to reduce heat, soot and failure points on LML platforms. Expect quicker turbo spool, lower EGTs and more consistent cooling for off-road performance builds. Custom tuning is required.

Features

  • Complete EGR and cooler removal for LML Duramax Engines
  • Lowers exhaust gas temperatures and backpressure
  • Improves coolant circulation by eliminating heat soak from the EGR cooler
  • Direct-fit plates, hose and hardware for a clean install
  • No intake manifold removal required in typical installs
  • For off-road/competition use only; tuning mandatory

Benefits

  • Power & Response: Faster turbo spool and stronger mid-range
  • Towing Stability: Lower EGTs under sustained load
  • Efficiency: Potential fuel economy gains with proper calibration
  • Reliability: Fewer leaks, clogs and EGR-related check-engine lights
  • Longevity: Less soot and heat stress on engine components

Compatibility

  • Trucks: 2011, 2012, 2013, 2014, and early 2015 GMC Sierra 2500/3500 and Chevrolet Silverado 2500/3500 (LML)
  • Vans: 2011–2014 and early 2015 GMC Savana 2500/3500/4500 and Chevy Express 2500/3500/4500 (verify LML fitment)
  • Confirm build date and engine calibration before purchase; early-2015 applicability varies.

Technical Specifications

  • Material construction: Aluminum intake block-off plate with O-rings; steel EGR block-off plate; silicone coolant hose with pre-crimped fittings
  • Typical install time: ~6–8 hours (varies by condition and tools)
  • Included components:
    • 1× EGR aluminum intake block-off plate with O-rings
    • 1× steel EGR block-off plate
    • 1× silicone coolant hose with pre-crimped fittings
    • 4× hose clamps
    • 4× socket head bolts
    • 5× hex head bolts

Installation & Notes

  • Difficulty: Moderate; hand tools and cooling system service required
  • Order of operations: Load custom tune before removing emissions parts to prevent DTCs/derates
  • Professional install recommended: Though you can install the kit yourself, professional installation is highly recommended to ensure everything is correctly fitted and tuned for peak performance.
  • Emissions disclaimer: Off-road/competition use only. Not legal for highway use. Check local, state, and federal laws.

Frequently Asked Questions

Will this fit early 2015 LML models?

Some early-2015 units are compatible. Verify your VIN/build date and LML configuration before ordering.

Is custom tuning required?

Yes. A calibration is required to disable EGR-related codes and optimize fueling and boost control.

Do I need to remove the intake manifold?

No in most cases. This kit is designed to install without intake manifold removal.

What changes should I expect after install?

Lower EGTs, quicker turbo response and more stable coolant temps when properly tuned.
