air bags for rear set up

hey all, i am putting an air 2link or 4 link set up on my 51 chevy styleline deluxe. i ordered a set of air springs from ride tech the fella at ride tech told me the springs i wanted twere the 9000. they arrived today and just look super small. they are rated for 1500 lbs a piece. has anyone used them or anything else let me know thanks

 

They would be fine for an air over leaf set up.I dont think they are big enough for a 2/4 link though.I have 2500# bags in the rear of mine.

 

thanks man i was thinking the same thing im gonna send these back today
