As we make our way into spring of 2026, one thing has become clear at Stainless Diesel, there is a favorite amongst our customers. While we pride ourselves on every manifold, piping kit, and of course every turbo that leaves our shop, the 5Blade Mafia™ Tow Boss 60/60 VGT Drop-in Turbo (2013-2018 6.7L Cummins) has officially claimed the title of our most sold product of the year.

But why has this specific turbo become the chosen one for thousands of Cummins owners? It’s not just about the power, it’s about the perfect balance of reliability, drivability, and that unmistakable Stainless Diesel whistle.

1. The 5Blade Advantage

The heart of this turbo is our signature 5-blade compressor wheel. In a world where many stick to factory blade counts, our 5-blade technology is engineered for a more aggressive bite of air. This means…

• Faster Spool-Up: No more waiting for the lag to clear when you’re merging onto the highway or pulling a heavy grade.

• Distinctive Sound: Let’s be honest, nothing sounds quite like a 5Blade Mafia turbo. It’s a badge of honor for your engine bay.

2. Built for the Tow Boss Lifestyle

We didn’t name it the Tow Boss by accident. This 60/60 VGT is specifically optimized for the 2013-2018 6.7L Cummins owners who actually use their trucks.

• Lower EGTs: High Exhaust Gas Temperatures are the enemy of a long lasting engine. This turbo is designed to keep things cool, even on a long haul through the mountains.

• Retains Exhaust Braking: Unlike some aftermarket upgrades that force you to sacrifice factory features, the Tow Boss maintains your full exhaust braking capabilities, which is important for safety and saving your service brakes while towing.

3. The Ultimate Sleeper

Many of our customers in 2026 are looking for a sleeper type setup. Because this is a true drop-in replacement, it fits exactly like the factory unit. It looks stock to the untrained eye, but it performs at a level that supports up to 600+ HP.Whether you're trying to meet "work stock” pulling rules or just want a truck that surprises people at the stoplight, this is the tool for the job.

4. Reliability

The reason this turbo is our top seller isn't just performance, it’s the peace of mind.

• Plug & Play: It comes with a calibrated VGT actuator and a new speed sensor. No custom fabrication, no headaches.

• Brand New, No Core: We’ve streamlined our process so you can get a new unit without the hassle of shipping a core back, getting you back on the road faster.

The sales from 2026 don’t lie. The 5Blade Mafia™ Tow Boss 60/60 VGT has become the industry standard for the 2013-2018 6.7L Cummins. It solves the common failure points of the factory turbo while giving you an immediate boost in performance and sound.

If you haven’t experienced the difference that a Stainless Diesel 5Blade can make, it’s time to see why the rest of the country has made this our #1 seller of 2026.
