Somebody correct me if I'm wrong but I seem to remember that a torsion bar has the same rate all the way through it's travel. Coils or leaf springs can be made so that the rate is progressive. If that's the case then maybe the bumpstops actually are intended to add to the rate as the suspension colapses.
yup.....t bars arnt progressive. probably why some say they get a harsh ride hafter cranking them.....instead of resting on the stops the truck kinda comes crashing down on em and then they start to do thier job. Sitting off em a little bit probly dont do much harm to the ride I wouldnt think??? Just my theory any way.....we could test it I suppose with a cranked "harsh riding truck" and throw some spacers in it between the bumpstops and the frame.
When I ditched my factory yellows in favor of timbrens I found that they were kinda squishy, you can push in a bit with your thumb. Timbrens are harder but dont really affect the ride that I can tell.
