2011 Cadillac STS Control Arms

Genuine GM control arms for the 2011 Cadillac STS, at wholesale prices. Factory bushings use the durometer GM specified, which is what holds alignment between services. Sigma platform rear-drive sedan, offered with the Northstar V8 and in supercharged STS-V form.

When to replace

Clunking over bumps, or an alignment that will not hold. On a full-size car, engine option is the main split here, and it runs deeper into the group than most people expect.

Buying OEM, briefly

• Factory warranty. Genuine control arms carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our control arms pricing against a counter quote.
• Genuine GM only. Every control arms listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the control arms before the box leaves.
• Central shipping origin. Dallas keeps control arms transit times short nationwide.

Avoiding the wrong part

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
