Installation Notes
Verify mount style, compressed length, and extended length before installation. This unit uses a stem upper mount and stud plate lower mount, so it should be matched to the vehicle’s original front shock configuration. Confirm that the application uses stock suspension components and compare the existing shock dimensions to Monroe 5809 before final assembly.
