Still not happy after a period of a few months with the rear monroe load assist rear shocks. Van wallows a lot now over bumps and bottoms out with light loads. Anyway just got a set of air bags to fit inside rear springs. Anyone done it? Van is 97 ext. Will post how it goes.

 

been running the same set of Air Lift bags in my '96 AWD EXT for 10+ years.
even towed 4000 lbs + TT several thousand miles.
spray the bags with silicone spray every year.
makes for a great ride even towing.
love the fact they're easily load adjustable for a long empty cruise, heavy hauling.

I use high pressure KYB gas shocks all around with the rear air bags

add performance poly strut link and sway bar bushings. Energy's are good. Moog also has a lower cost line

package together takes the floating feeling out the the van, great cornering, adjustable handling

 

Installed those rear bags and a. Running with 16psi. Van doesn't wallow or sway with a load now. Very happy.

 

I ran those air bags and air shocks my 88' Aero. Overall I was happy with what they did, which was maximum hauling capacity. I still can't believe how much weight I moved with that van! On older style (rwd) suspensions, air bags inside do wonders.....
