The baja grocery getter, is the 6" lift, custom long radius arms, etc.
It'll need some leaf springs in the back, and will require welding the radius arm mounts on the frame.
In my opinion, the bent beam kits are better because they correct the camber for the most part (will still need dialed in) and their radius arms have more caster built into them, so the van will drive straighter. The drop down brackets, just move everything down, keeps it all stock, ground clearance isn't much gained, and the amount of leverage on the brackets is big.
Shoot Jeremy at weldtec a call/email, he'll spend the time and go thru all the options, bilsteins, fox, blocks, add a leaf, full custom leaf pack.
On my van, I went with the 4" suspension system which is basically, the ocotillo cruiser front kit, performance add a leaf in rear, I opted for the agile off-road custom fox shocks, and the addition of the steering dampener. I didn't wanna go with a 6" kit, so the 4" system worked a treat, the van handles better, corners better, takes the bumps/potholes/dips etc 100x better than before. VERY pleased.
