Availability of Firestone Ride-Rite LS Rear Shock Absorbers # F4354  

I am attempting to match a non load-adaptive front shock to this load-adaptive rear shock. I looked on the Firestone web site and it does not show this load-adaptive shock to be available. Has the 4354 been discontinued? I see in your photo that it is a Rancho shock. if the 4354 has not been discontinued, what series Rancho shock would match the 4354 for the front? My vehicle is a 2005 Ford F-350 DW CC with the Tow Boss package and 6.0 engine. Thank you,
