adjusting spring plates

I'm new to busses, maybe someone can help me. Why is it so common to lower a bug by adjusting the spring plates in the rear, but not a bus? Does it have to do with the gear reduction boxes? Thanks..

There is only so much lowering that can be done by adjusting torsion bars. On the bus the height is so great that more is usually needed in addition to rotating the bars. On the 67 and earlier vans most guys are now going with the T-1 or T-3 IRS kits from Wolfgang or Bus Boys to get the job done. You gain some top end cruising speed in the process as well. Good Luck.

I had a knuckle-head customer adjust his rear bars on his 66 kombi to lower it considerably,about 4 inches and still had his reduction boxes intact.This actually bent the side flanges on the axle tubes,and destroyed the tranny end gears.Great idea huh? It sure looked cool though.

The real answer is that as you lower the bus, the redux boxes get turned. By design the more you turn them, the less the gear oil will do it's job and you'll end up with burned out Redux gears and bearings ect. You can get away with a small amount of lowering in the back, but not really much before you start comprimising the stock redux box setup. If you want slammed, go with a lowering kit. You can get lowered splindles for the front.
