Looking at new Shocks for my 99 ML, whats the difference between 163-320-23-13 AND 163-320-24-13? I know the later chassis code vehicles call for the 163-320-23-13 but what is the difference between the two?
Different shock valving?
Different spring rate?
Different ride height?
The front shocks are also different by 1 number for the respective chassis codes. Would like to know the difference.
163-326-11-00 and 163-326-12-00 (called out for my 99)
