When building or maintaining a high performance diesel, it’s easy to get lost in the big items. We obsess over the size of the turbo, the exhaust manifold, and the tuning of the fuel system.

But there’s a little hero holding all that horsepower together, subjected to some of the most brutal conditions under your hood.

We’re talking about your turbo to manifold mounting hardware.

If you've ever dealt with an exhaust leak, a backed out bolt, or a snapped stud while trying to haul a heavy load or make a hard pass at the drag strip, you know exactly how frustrating bad hardware can be. That’s why we engineered the Stainless Diesel Turbo to Manifold M10 x 1.5 Mounting Stud Kit. Here is why this small upgrade makes a big difference…

The Brutal Environment Under Your Hood

The connection between your exhaust manifold and your turbocharger flange is a literal pressure cooker. IT'S HOT! It has to survive:

• Extreme Heat: Exhaust gas temperatures (EGTs) can easily reach over 1,200°F under load. This constant heating and cooling causes metals to expand and contract.

• Heavy Vibration: Diesel engines and high boost setups create intense vibrations that naturally want to back hardware right out of its threads.

• Massive Boost Pressures: Keeping a flawless seal on a T3, T4, or T6 flange requires relentless, uniform clamping force.

Standard hardware or old, worn out bolts often stretch, lose their strength or back out under these conditions. The result? A blown turbo gasket, a major exhaust leak, a loss of drive pressure, and a noticeable drop in boost and performance. Nobody wants that. 

The Stainless Diesel Mounting Studs

We designed this kit to give you peace of mind. Built for boost, vibration, and extreme heat, our kit provides the ultimate clamping force to keep your turbo sealed tight to the manifold.

1. Engineered for Precision Fitment

The M10 x 1.5 thread pitch is the standard for a wide range of diesel and high performance turbos. Whether you are running a standard setup or custom piping, these studs offer smooth engagement and maximum thread contact to prevent stripped holes in your expensive manifold.

2. Standard Flange Head Locking Nuts Included

A stud is only as good as the nut holding it down. Every kit comes complete with heavy duty flange head locking nuts. The wide flange distributes the clamping load evenly across the turbo foot, while the locking mechanism ensures that engine vibrations won't back the nuts off, even during hard pulls.

3. Tailored to Your Specific Build

No two turbo setups are exactly the same, which is why we don't offer a one-size-fits-all solution. Our M10x1.5 kit is available in customizable configurations:

• Short Studs: Ideal for standard, direct turbo-to-manifold mounting where no spacer is used.

• Long Studs: Specifically designed for setups utilizing a 1-inch turbo spacer between the manifold and the exhaust housing.

• Mounting Style Options: Choose between a full set of 4 Studs or a 2 Studs and 2 Bolts configuration depending on your manifold clearance and installation preferences.

Don't Let a $30 Part Ruin Your Drive

Whether you are replacing worn hardware during routine maintenance, dropping in a fresh Stainless Diesel 5-Blade turbo, or fabricating a custom compound turbo setup, upgrading your mounting hardware is the smartest insurance policy you can buy.

At just $29.50, this kit ensures proper alignment, an unbreakable seal, and long term reliability. Don’t wait for a noisy exhaust leak or a lost bolt to slow you down.
