GKTech Nissan S13 240sx Rear LCA weld in Reinforcement

The GKTech Rear Lower Control Arm (LCA) Weld-In Reinforcement Plates for the S13 240SX, Silvia, and 180SX are designed to address a known weak point in the factory suspension. The OEM LCAs, especially when used with stiffer bushings, coilovers, or extended arms, are prone to flexing or even cracking under stress. This kit boxes in and reinforces the factory control arms to improve durability, rigidity, and alignment consistency.

Cut from high-tensile steel, these weld-in plates are shaped to contour precisely to the OEM LCA structure and are ideal for cars that see hard driving, drifting, or track use.
