GKTech Front Upper Camber Arms for Lexus IS 200 & 300 (XE10, 98-05)

GKTech Front Upper Camber Arms Specification

The GKTech front upper camber arms (FUCA) for Lexus IS200/IS300 and Toyota JZX110 are designed to precisely correct and adjust front camber, especially on lowered vehicles where excessive negative camber reduces tire contact and traction. As direct replacements for the OEM arms, they offer a wide adjustment range from -34 mm to +22 mm, allowing users to restore proper alignment or dial in aggressive setups. In addition, their unique design incorporates adjustable caster via stackable shims, enabling fine-tuning of suspension geometry beyond standard camber adjustment.

Constructed from high-strength laser-cut steel with CNC-machined ends, these arms are CAD-designed, FEA-tested, and TIG-welded for durability and precision. They feature high-misalignment PTFE-lined spherical bearings that eliminate the flex of factory bushings, providing a more direct and predictable steering response. Finished with an anti-corrosion E-coating and equipped with dust boots, they also allow on-car adjustment, making them a robust and practical solution for performance-oriented street or track builds.
