The lift is simple, for the front of the van I just had to crank the torsion bars a bit and also trim some metal with a grinder.
The back is tricky, we don't have spacers specifically made for our vans. Some guys will buy Ford Aerostar springs and cut them down in size to fit.
But I simply bought Daystar KT09100BK Toyota 4runner spacers, they fit 90-95 4runners I believe. You have to cut a 1/4'' out of them to lessen the diameter to fit the springs on the Toyota Van.
They gave me a 1.25'' in the rear and I matched the front lift to that 1.25'' increase in the rear.
I also did all new shocks while I was down there messing around.
The best part is now that I went up from 185's to 27in General Grabbers and the lift my oil pan sits 9'' of the ground instead of 6''. This is a lot for the van and I will feel safer going down forest service roads.
