GKTech Nissan 240sx/Silvia K-Frame/Tension rod mount weld in reinforcement kit - S13/180SX

The GKTech K-Frame / Tension Rod Mount Weld-In Reinforcement Kit for S13 240SX, Silvia, and 180SX chassis is built to address a known weak point in the OEM front subframe (K-frame)—the tension rod mounting area. Under aggressive driving conditions such as drifting, time attack, or heavy braking, this area can flex or even crack, leading to poor alignment retention and unpredictable handling.

This kit includes laser-cut high-tensile steel plates that weld directly to the K-frame, boxing in the tension rod mounts to eliminate flex and add durability to your front suspension setup. It’s a must-have reinforcement for any S13 that's driven hard.

Key Features:

• Reinforces Tension Rod Mounts: Prevents cracking and flex under load

• Improves Front-End Rigidity: Maintains suspension geometry under stress

• Precision Laser-Cut Steel: Shaped to fit OEM S13 K-frames with minimal prep

• Motorsport Proven: Trusted by drift and grip drivers alike
