Dobinsons options

Forgive me if it’s been answered- two questions-
1. Rear factory air- same shocks as normal suspension?
2. Looking at a dobinsons setup with three different ideas. Use case is commuting 80%, towing 15% and light off-road 5%. 2” lift in front, 1.5 rear with the AFe airbag arms. I’ve got nokian NAT 295/70/18 on trd pro wheels. Long boy crewmax/6.5 bed. Supporting mods are trd grey upper control arms and trd lift axles.
A. IMS all around- cheapest and probably way more than I need.
B. MRA all around, priciest, and definitely way more than I need.
C. IMS front, MRA rear. Adjustable rear for towing, which mostly affects the rear.

I am a tinkerer and like the idea of the MRA- got the money but it seems like a lot to spend on something that probably won’t make that big a difference. Anyone still doing holiday sales? I missed the exit off road sale because I was indecisive. If I can find a sale I’ll call the dealers, but thought someone may have a less biased opinion when they aren’t selling you stuff.

 

Dobinsons suspension is not compatible with factory rear suspension.

You would have to remove that and go with a coil spring setup in order to use Dobinsons.

 

Not even the shocks?

 

The shocks are made for the lifted vehicle, and Dobinsons parts don't work on an air-equipped model. I don't know anyone that has tried the shocks in conjunction with the airbag vehicle.

 

Ok interesting. My rear is lifted 1.5” using the afe rear height sensor arms:

Seems like the dobinsons shocks might work since they are designed for between 1-3” of lift?
