GKTech Nissan S13 Silvia frame rail extension reinforcement brace

The GKTech Frame Rail Extension Reinforcement Brace is designed to strengthen the front tension rod mounting area on the Nissan S13 Silvia and 180SX by reinforcing the weak, crash-prone section of the front frame rail. In stock form, this area is vulnerable to cracking, flexing, or distortion under hard braking or during front-end collisions. This brace extends and reinforces the factory frame rail, creating a more solid platform for tension rod brackets and improving chassis integrity.

Fabricated from laser-cut steel and finished in a corrosion-resistant coating, this brace is an easy bolt-on solution that installs using existing factory holes with the included hardware—no cutting, welding, or fabrication required.
