I should clarify what I mean. The Sumosprings measured about 5in before installing. At rest, they measure 4.25in. If I lift the van by the axle, They measure just a hair under 4in. When I lift the frame, The maximum distance between the mounting plate of the Sumosprings and the pad on the axle is just under 7in. That means the Sumospring is about 80% compressed at rest. They say the blue shouldn't be regularly compressed more than 70%, which only gives 0.5in of travel before "damage" is done.
I would assume that while driving they will compress a little more than when I measure in the driveway, but still, I see approximately 1in of travel lost just from the weight of the van and only 0.25in of potential up travel before maxing out the Sumospring. My swaybar is probably also affecting the theoretical maximum axle travel, but given I drive with it every day, I'm not inclined to disconnect it just for measurements.
So this is a lot more of what I expected when I ordered. It's impossible to tell size via the photos online, but my Sumosprings are significantly larger than I expected compared to the old bumpstops. I'm pretty sure that if I remove the spacer welded to the frame I would have a setup that looks similar to yours.
I've had to drive the van the past few days and it's immediately noticeable that the ride quality has declined. As expected, you would say it feels like it's riding on the bumpstops :b1:. Every little bump is felt.
I do have an email out to Super Springs (holiday weekend doesn't help) to confirm that these are the correct Sumosprings for my van, and see if they have a recommendation about cutting out the space to gain that 2in of space. I looked at the F-350 products and application and they do show different parts. They also have a video and it shows a very slight contact while driving, certainly less than what I'm seeing.
I appreciate all your help!
