Product Description

The SuperPro SPF3090K Front Lower-Inner Control Arm Bush Kit is designed to replace the original rubber bushings in the lower-inner position of the front control arms on select Lexus performance sedans. Polyurethane construction offers increased durability and resistance to wear compared with stock rubber, helping to preserve suspension geometry under braking, cornering, and acceleration loads. This upgrade enhances steering precision, reduces unwanted play, and helps maintain proper wheel alignment for improved handling stability and tire wear characteristics.

Fitment is confirmed for the **Lexus LS400** from **1990 through 2000**, making this kit ideal for owners looking to refresh aged suspension components or upgrade for improved steering and handling response without replacing entire control arms. A professional installation is recommended, and a front wheel alignment should be performed after installation to ensure optimal suspension geometry and tire life.
