💰 Eliminate the infamous EGR cooler cracking issue and the risk of coolant entering cylinders (Hydrolock) — replacing an entire engine can cost over $10,000.
⛽ With ECU tuning, gain 3%–6% better MPG. The fuel savings from heavy towing add up significantly over time.
🔧 Remove the EGR valve and dual EGR coolers in one go. Never deal with EGR‑related failures again — say goodbye to repeated repair bills.
⚡ Fresh, cool air flows in without exhaust interference, dramatically improving intake efficiency. More stable during heavy climbs and long hauls.
🏗️ Precision‑machined with zero tolerance, withstands 1,472°F without warping, and anodized for corrosion resistance — outlasting cast parts many times over.

Not fit cab&chassis
Designed for 2011-2016 Chevrolet Silverado / GMC Sierra 2500 HD / 3500 HD pickup trucks equipped with the 6.6L V8 LML Duramax diesel engine. This kit physically removes and bypasses the factory EGR system, fundamentally preventing hot exhaust gases from re-entering the intake and eliminating carbon buildup, power loss, and other common issues.
Built from 6061 CNC-machined aluminum and stainless steel, this kit is engineered for heavy towing, farm use, and off-road modifications.
No additional hardware needed. Everything required is included in one box:
CNC-machined from 6061 aluminum (silver anodized), these plates seal the EGR ports on both the intake manifold and exhaust manifold:
| Comparison | Cast Aluminum (Cheap) | CNC 6061 Billet (This Kit) |
|---|---|---|
| Dimensional Accuracy | Loose tolerances, poor seal | Precise, perfect seal |
| Heat Resistance | Deforms at high temps | Withstands 1,472°F (800°C) without warping |
| Corrosion Resistance | Average | Anodized for long-term protection |
| Durability | Short lifespan | Built for severe diesel duty |
Both kits are identical in function, materials, and craftsmanship – the only difference is the finish color:
The 6.6L Duramax LML (2011-2016) is widely known for its weak EGR cooler – one of the most common and expensive failures:
1. EGR Cooler Internal Cracking (Most Common): Replacing a factory EGR cooler costs $1,800 – $3,200 in parts + labor, and it often fails again within 40,000 – 60,000 miles
2. Intake & EGR Valve Clogging from Soot: Frequent P0401 / P0402 (EGR flow malfunctions)
3. Check Engine Light and Limp Mode: Hydrolock from coolant ingestion can require a full engine replacement – over $10,000
Reliability Upgrades
Performance & Fuel Economy
After installing the EGR delete hardware, you MUST use an ECU tuner that supports "emissions-off" calibration. Without it, the ECM detects missing EGR flow, triggers Limp Mode, restricts power, and turns on the check engine light.
Recommended Tuner: H&S Mini Maxx V2 (popular choice for LML)
