Thats correct. I wanted better ride quality at the same ride height of cranked torsion bars.
It still bounces if i drive the van too hard. But its much improved. Speed bumps dont buck me out of my seat any more.

I didnt hear you say that you replaced the front shocks.

I really believe bounce should be controlled by shocks.

I would like to see someone fit adjustable rancho shocks.

Maybe dual shocks.

We gotta think out of the box with These vans as there is no aftermarket support.
