Cusco Lexus IS250/IS350 Adjustble +/- 15mm Rear Upper Arm (Front)

This is the Cusco adjustable rear upper arm for your 2006-2014 Lexus IS250 or IS350. This part is designed to correct alignment issues that can arise after lowering your vehicle or when you want to fine-tune your suspension geometry. It allows for adjustments to camber, which is crucial for ensuring your tires make proper contact with the road and wear evenly.

Cusco builds these arms from strong steel with a durable finish to resist corrosion. The design allows for a range of adjustment, typically +/- 15mm, giving you the flexibility to dial in your alignment precisely. This is particularly helpful if you've installed lowering springs or coilovers and are experiencing unwanted camber changes. Getting the alignment right ensures your car handles predictably and maximizes tire life.

When installing adjustable arms like these, it's always a good idea to have a professional alignment done afterward to ensure everything is set correctly. This part is the front piece of the rear upper arm assembly.
