🛠️ LML 63mm 5Blade Mafia™ Drop-In Turbocharger – Stock-Appearing Upgrade for 2011–2016 6.6L Duramax
Give your 2011–2016 Duramax LML the performance boost it deserves with the Stainless Diesel LML 63mm 5Blade Mafia™ Drop-In Turbo. Designed for daily drivers, tow rigs, and Work Stock competitors, this turbo is a true bolt-on upgrade that delivers faster spool, lower EGTs, and the signature whistle of the 5Blade Mafia™.
Rated for up to 660 HP with supporting mods, this unit features a 63.5mm billet 5Blade compressor wheel and a 66.5mm 10Blade turbine. It’s ideal for stock-fueled trucks and retains the factory exhaust brake, making it the perfect balance between performance and reliability.
📌 Note: For trucks with a larger CP4 or CP3 conversion, we recommend stepping up to the 65mm turbo for better fueling match.
