Installation Notes and Tips

Verify the vehicle’s front upper suspension configuration before ordering, especially on Buick LaCrosse, Buick Regal, and Saab 9-5 models with performance suspension and Cadillac XTS models with 5-lug wheels. Confirm mounting hole spacing, stud type, and dimensions against the original part before installation.
