Bilstein shocks question
 

I bought some used Bilstein shocks for my 1995 Rangie Classic (air suspension). After checking on part numbers I realized the part numbers are different for air suspension vs non-air.
The ones I bought are front: 0243 rear: 0253
Bilstein website shows this part numbers for air suspension: front: 2153 rear: 2152
Do you guys know if there is a significant difference between these shocks?

Thanks.
