GKTech Nissan S14/S15/R33/R34 HICAS Lock bar

The GKTech HICAS Lock Bar is designed to eliminate the rear-wheel steering system found on HICAS-equipped S14, S15, R33, and R34 chassis. While HICAS can offer dynamic steering benefits on the street, it's a common weak point in drift, grip, and motorsport applications, where predictable rear-end behavior is critical. This lock bar replaces the factory HICAS rack, effectively converting the rear suspension to a non-HICAS setup and locking out any rear steering movement.

Made from TIG-welded high-strength steel, the bar bolts directly to the factory mounting points for a solid, hassle-free install. It’s a must-have for drivers looking to remove the complexity and flex of the factory HICAS system.
