3500 Air assist Towing Shocks?

[carlrx7]

Getting close to 50k on the clock and I'm looking around for Shocks. Plenty of "Shock finders" out there, but i dont see any special consideration for 3500 duallys with Factory Air assisted suspension. The part number i pulled off the rear shock is this one: https://www.moparpartsgiant.com/parts/mopar-pkg-part-suspension~68349426ac.html

Part Discontinued

Any internet ninjas ou there can help me out? Is there a better Aftermarket solution that would fit the air assist?
