QA1 GM Pro Front Coil-Over System - Single Adj. - 10in x 450lbs/in - Flat Large - Aluminum - GS507-10450C FAQ

Install and care: coilovers

Before you start

  • Read the maker's guide and note the recommended ride-height range for your car.
  • Book an alignment for after the install; the car needs one.

Do

  • Set all four corners to the same drop before the alignment and re-check the height after the first drive.
  • Keep the threads clean and lightly lubricated so the collars still turn next season.

Don't

  • Don't go lower than the maker's range; it costs ride quality and tire life.
  • Don't skip the alignment.
