Construction & Design

These shock tower nuts are manufactured from premium Grade 5 titanium, a material known for its exceptional strength, low density, and outstanding corrosion resistance. Titanium’s natural properties make it an ideal choice for suspension hardware, where durability and weight savings are critical. The nuts are precision CNC-machined to exact OEM specifications, ensuring a perfect fit and reliable clamping force on the shock tower studs.

The flare nut design enhances thread engagement and distributes load evenly, reducing the risk of loosening under high vibration or dynamic driving conditions. The titanium finish not only offers a sleek, high-end appearance but also resists rust and oxidation far better than traditional steel nuts, extending the life of your suspension components.
