Product Details
If you're working on the rear suspension of an Infiniti M35h, M37, M56, Q50, Q60, or Q70, and you've found a worn or bent rear lower control arm, this SPC Performance replacement is a solid option. It's built to match the stock arm length and uses high-strength steel for durability. This part is designed to directly replace the original equipment part number 551A01MA0D, helping to restore proper suspension geometry and handling.
The control arm features OE-style rubber-bonded bushings, which are important for absorbing road vibrations and reducing noise inside the cabin. This helps maintain a comfortable ride even with the strong steel construction. While this arm maintains the stock length, SPC also offers an adjustable link (#72245) if you need to make camber adjustments after installation.
