While pondering all of my lowering options, I discovered that Monroe makes several air shocks that fit the front of our vans..... The Max-Air ma812 was the one I chose because it is the shortest..... I also determined that the air fittings and hoses on these shocks are kinda crappy and don't interface with normal 1/4" air ride stuff, so I spent some time at my local industrial supply house finding fittings to adapt the proprietary fittings on the shocks to 1/4 air line
Some Pics:
Basically, I wanted a male flare to nest into the open end of the fitting
A straight threaded sleeve that is 7/16 x 20 threads onto the shock....It needs to be EXACTLY one inch long, comes a little longer so I had to cut and run a tap through it...
The male flare is also 7/16 x 20 and has a female pipe thread in the other end
With the 1/4" air-line fitting screwed into it...
Hole cut through the fender for the fitting... Air lines will run inside the cab and the fitting will be sealed with a shift boot
Here is a picture of the left shock bolted in place... note the air fitting through the fender.... this shot also shows the double stacked 6 degree shims (yes 12 degrees!) that it took to get the axle to 5 degrees positive ( less when I put taller rear tires on it)
My drop is expected to work at the static ride height, but because of my launch-ramp driveway with excessive bottom transition, and because these vans have a lot of front overhang....I need to have the ability to raise it enough to get to the street without scraping....
