Gadwall,
I am curious as I never used Sumos.
Are the Sumos longer than the OE front bumpstops?
We put a set on the back of our 2008 F250.
The OEM bumpstops are not intended to come into contact unless you bottom out the suspension. In normal use, they should never come into play.
The Sumosprings go in their place and are significantly taller (I believe it was 7" vs 3").
When installed on ours, the suspension has to compress about an inch before they come into contact and they are progressive (at first they provide little support and then it ramps up as you compress more). This means when lightly loaded, they don't feel as harsh if you do hit a bump.
They did come with an optional spacer, so they would always be in contact even when lightly loaded and thus provide more (not necessarily better) support.
We chose them over air bags as there is basically nothing to fail. The downside is you can't adjust on the fly but we are towing not carrying a truck camper. Installation is easy, 1 bolt to remove the old bump stop (the biggest challenge if the truck isn't newish) and 1 bolt to put the new spring on.
Front coil springs are a bit different design and we didn't get those.
