Pictured is the Tanabe DF210 Springs 1990-1994 for LS400 (UCF10). Make note that the springs are always installed right-side up.
For the front springs notice how the DF210 logo is right-side up and the part number is printed on the spring itself. In order to determine whether the springs are for the spring or rear you’ll see the F (front) or R (rear) printed after the part number.
For the rear springs you will see how the part number ends in with the R (rear). The logo is right-side up which ensures that the spring will be installed correctly.
