Sumo Springs on Sprinter Question

Hi folks. I'm wondering if anyone has put Sumo Springs on their 2017 Mercedes Sprinter? It is easy enough but while watching the YouTube University on installing SumoSprings there is no reference to a bump stop on the axle. Yes, there is one on the Fram that is replaced using the Sumo Springs but mine has a bump stop also on the axle just below the frame bump stop. I'm wondering if I am supposed to remove the stop on the axle so the Sumo Spring contacts the axle instead of the stop located on the axle. Anyone got any experience with this one?

Sumo Springs on Sprinter Question

Just a guess, but as the Sumos are designed to replace the bump stop and fill the distance between frame and axle, I’d take all bump stops off.

Getting ready to upgrade our Sprinter RV with Sumos, rear shocks and HD sway bar to tame the driveway rocking and highway stability.

Why not send an email to Super (Sumo) Springs and ask them? I seem to recall something about different SS models only work with different Sprinter model years because of the axle bump stops, but can't recall exactly the issue.

The new generation VS30 Sprinter was introduced in 2019. There are differences in suspension from prior years.

I had to do some research to determine the proper upgrade pieces for our 2019 Winnebago View.

Some websites mistakenly indicated part covered the VS30 when they really didn’t.
Best to contact sites and verify figment.

And you nailed my question so I did ask Sumo and they said to leave the half moon bump stop on the axle and replace the frame mounted bump stop on the frame. Seemed weird to me but that's what I'll do. Thanks

Your advice was well taken and I did just that. They advised that the half moon bump stop which is mounted on the axle stays and the frame mounted bump stop is removed and replaced with the Sumo. Thanks,

Oddly enough, last week I ran into a similar puzzle when I installed my SSR-338-54 rear SS. I left the axle bump stops in place, as you'll be doing. At first it didn't look right, but when I actually got underneath the chassis and installed them, they fit perfectly.
The curb roll/wallow is much better, and I'm not going to bother adding fronts, unless something else changes. I was a little concerned about the front end alignment, and the SS live chat guy said it shouldn't need an alignment. However, I found more than a few mentions of doing one after installing the SSF-106-40/47 models due to a change in camber. My Navion rides well and tracks well and there's no sign of odd front tire wear, so I'm leaving it alone for now.

That's really good to know that the rears helped with the sway. I did look at the stock sway bar and it looks stout if you can rely on looks. I may just bite the bullet and go with rear sumos and the hell wig sway and be done with it. I will report back.

THANK YOU all for your input. It is invaluable to making good decisions.

Be aware that Sprinter Sumos come in two flavors: Standard and heavy duty.

Sumo Springs, Hellwig Sway Bar, Bilstein 46MM RV Shocks

I changed everything in the driveway 2 weeks ago. 2 1/2 hour job, Not tough at all! Works great, cuts the driveway rock into nothing, Helps with Sway but still disrupted Motorhome when going 70 MPH on freeway and a semi passes! MUCH< MUCH better than it was! Sumo 1400#: $295.99 E-Trailer, Hellwig Sway Bar: $373.21 E-Trailer, Bilstein RV Shocks $233.56. WELL Worth Your Time, ADDED SAFETY IN HANDLING!

FYI … SuperSprings (the manufacturer of the SumoSprings) currently has a 25% off sale going on now, through the end of this month, on anything/everything.

Prepare your order, apply code “SUPERSALE2021” and it will knock off 25%.

https://www.superspringsinternational.com/

I have no affiliation with them, just a happy customer.
