Key Features

• Direct Fit: Designed as an OE replacement to install without modification and match factory mounting points for the 1990-1994 Lexus LS400 passenger upper position.

Who It's For

This control arm is aimed at owners of a 1990-1994 Lexus LS400 who need a front passenger-side upper control arm replaced with a part that mirrors the original equipment fit and function. It suits DIY enthusiasts with intermediate mechanical skills and professional shops that prefer spare parts matching factory references for quick turnaround.

It is not intended for drivers seeking performance suspension upgrades or heavier-duty competition components; those buyers should look for reinforced or performance-specific arms.
