If you own a 2013–2018 RAM 2500 or 3500 with a 6.7L Cummins, you already know the truck is an absolute force to be reckoned with. But you probably also know about its weaknesses... the factory VGT. Over time, the stock turbos are notoriously prone to failing, sticking or giving out just when you need them most.

When it comes time to replace it, you’re faced with a choice. Do you drop your hard earned cash on another weak OEM replacement? Or do you upgrade to something that solves the reliability problem while also unlocking the true potential of your Cummins?

Enter the NEW Stainless Diesel- The Boss 63/67 VGT Drop-In Turbo.

It’s a direct, bolt-on performance upgrade that delivers massive power, keeps your street manners intact, and sounds absolutely mean. Here is why the Boss 63/67 VGT Drop-In Turbo is earning its name as the ultimate upgrade for your 6.7L Cummins.

What Makes the VGT BOSS Different?

A lot of aftermarket turbos force you to choose between big track power or everyday driving comfort. The Boss 63/67 VGT Drop-In Turbo gives you both. It is a complete drop-in turbo upgrade, meaning it bolts directly into your factory setup with absolutely zero fab work required.

But inside that stock style housing sits a completely reengineered powerhouse.

1. The 5Blade Mafia™ Advantage

At the core of this turbo is our 63mm billet 5Blade Mafia™ compressor wheel. Unlike factory wheels with more blades, our aggressive 5-blade design allows for vastly improved airflow and quicker response. Paired with a massive 67mm high-flow turbine wheel, this combination drastically lowers your EGTs while generating a faster spool and incredible boost control.

2. Mass Power Capability (Up to 700 HP)

Looking to build a formidable street truck or compete in Work Stock pulling classes? The Boss 63/67 VGT Drop-In Turbo is ready to party. With proper fueling upgrades, this drop-in turbo can comfortably support up to 700 horsepower.

3. Keeps Your Factory Exhaust Brake

One of the biggest complaints about deleting or swapping out a VGT turbo is losing the exhaust brake, which is essential if you pull heavy trailers. The Boss 63/67 VGT Drop-In Turbo retains full factory exhaust brake functionality. You get aggressive street performance without sacrificing safe towing and daily drivability.

4. That Unmistakable Stainless Diesel Whistle

Let’s be honest: performance matters, but sound matters too. The aerodynamics of our 5Blade Mafia™ wheel combined with the high-flow turbine produce that loud, crisp, aggressive turbo whistle that every diesel enthusiast loves. Want to take it a step further? Opt for our 67mm 9Blade high-flow turbine wheel variant for even higher flow capacity and an even crazier whistle.
