GKTech Nissan S14 240sx Rear LCA weld in Reinforcement

The GKTech Rear Lower Control Arm (LCA) Weld-In Reinforcement Plates for the S14 240SX are designed to strengthen a known weak point in the factory suspension. When subjected to hard driving, drifting, or aggressive alignments, OEM rear LCAs can flex or crack, especially when paired with stiffer bushings or coilovers.

These laser-cut high-tensile steel plates box in and reinforce the factory LCA, increasing structural rigidity and preventing failure. Perfect for anyone looking to improve the durability and reliability of their S14’s rear suspension while retaining OEM geometry.
