Thought I would document this if anyone else can benefit from it.
A little back story...My aunt bought this brand new to use as a wheelchair conversion van. Years go by and she gets a newer van and gives me this for free. I use it for my band and movin stuff around. I've had it for about 12 years now and its probably my best running vehicle haha. I use it as a second daily driver for work or around town.
I'm trying to lift it about 2-3 inches and put some 30 or 31 inch tires. So far I replaced the rear leaf springs (4 leaves and 1 overload) with new stock leaves (5 leaves with 1 overload). FInished up today and it added about 2.25". I was surprised of the lift I got with only new springs!
Next move is to install the coil spring spacers which are advertised to lift it 2-3 inches. If that lifts the front too high ill add a 1 inch block in the rear or take a leaf from the old set and add to the new set.
This will be a slow moving van and thread. Enjoy!
