Kill Devil Diesel Crank Flange Adapter Stud Kit
Ford 6.0L & 6.4L Powerstroke
When pushing the limits of the 6.0L and 6.4L Powerstroke platform, the factory crank flange hardware becomes a known weak point. On high horsepower builds, fretting and movement between the rear crank hub, crankshaft, and flexplate or flywheel can lead to serious failures.
Kill Devil Diesel developed this exclusive solution to eliminate that problem entirely.
Engineered to Solve a Real Problem
Unlike traditional bolt kits, this system converts the fastener into a mechanical locating feature. Each stud is designed with a precision shoulder that acts as a dowel pin, positively locating and locking the rear crank hub in place.
No movement. No fretting. No compromises.
In the past, we addressed this issue by machining the crankshaft and adding dowel pins. While effective, it added cost and complexity, and in extreme horsepower applications, even dowel pins could fail.
This kit replaces that approach entirely.
- No additional machining required
- No small dowel pins to shear
- Stronger, more reliable solution
Premium Materials. Maximum Clamping Force.
Developed in partnership with P1 Manufacturing, leaders in aerospace and high-performance fasteners, these studs are made from their proprietary S220 material.
The result:
- Significantly increased clamping force
- Improved load distribution
- Strength equivalent to adding an additional fastener
- Superior resistance to fatigue and deformation

The Bottom Line
If you are building a serious 6.0L or 6.4L Powerstroke, this is not optional. This is the most effective way to secure the rear crank hub and prevent one of the most common failure points in high horsepower applications.
