The “Do It Once” 6.7 Powerstroke Rocker Fastener Upgrade

If you’ve ever had the valve covers off a 6.7, you already know the factory rocker bolts are torque-to-yield: one-and-done, stretched, and not exactly confidence-inspiring when spring pressure (or boost) goes up (plus, they're pretty famous for breaking randomly too). Ontork’s stud kit is the opposite: reusable, stronger, and designed to hold preload consistently instead of stretching and losing it over time. The studs are rated at 221 KSI, and the kit includes the studs plus matching high-strength 12-point nuts. Fits all 2011+ 6.7 heads (2011–2019 and 2020+)
