Rear Air suspension replace to springs
I put in many hours with phone calls, online/parts searches , VIN & RPO code translations for what suspension package was on my 07' denali 4WD;;
seems nivomat- is this air suspension - maybbe, but is the ZW7 suspension ;
so I saw coil springs on my rear end, previous owner must have done the conversion from air.
But when towing 4500 camper- back end squats , so I am ordering the AC Delco PRofessional premium coil springs - 45H2133 - VARIABLE rate ....stay tuned.
