Which shocks for the rear 2015 24R?

But as stated earlier I haven't had a chance to test them as yet. The rig is parked till mid January.

The Dr. has a great point, thank you. Will keep an ear out to hear how the #SSR-336-54-1 rear Sumo's work for you. They are a bit more spendy but I am sure they are even more awesome.

As for the part numbers I posted, several of us on this forum have them and are very impressed with their performance.

Was under my 2016R today and I have rubber stops on the frame. Found out my frame is a 2015. I have only driven unit 15 miles and am living in it but am getting ready to make a trip, 875 miles, to Vegas. I have Helwig bars, and am pulling a fairly light 6x12 enclose so debating the sumo springs. Any thoughts?

Yes, my advice is to drive it "as is" and see what you think of it... A stock MBS isn't unsafe to drive "as is" by any means. And without a baseline you won't really know if you need to improve the suspension.

I'm still "on the fence" as I haven't driven our "W" far enough, or in enough varying traffic conditions, to determine if I need Sumo's. When I get a couple thousand more miles then I'll decide on both upgrading to better shocks and the Sumo's.

That's my thoughts!

In CA, we have a lot of mountain and canyon roads. The Sumo's really shine here, in addition to their other benefits.

Great advice. will post when I arrive in Vegas.

Just added the front and rear SumoSprings to my 2014 S. I am a retired lawyer with minimal mechanic experience. If I can do it, anybody can.
A couple of tips for the DIY crowd. The front OEM does not have a 10mm bolt as the Sumo pamphlet states. It is 1/2". You have to put a washer and bolt on the Sumo but cannot get fingers into tight space. Put a dab of caulk on the washer so it sticks to the bolt.
When you try to get the OEM rear bumper stop off you have to pry it off with a screw driver. The driver side came off fairly easily. The muffler side is hard to get at with a long enough screw driver. Use a boxcutter and just cut it off at the front or back metal bracket. Very easy.
You have to force the new SumoSpring into the metal bracket. Clean the bracket and spray it with silicon spray. It slips in with little effort.
I already had installed the Helwig anti-sway bar and it made a noticeable difference, but the addition of the SumoSprings front and rear make a big difference. When passed by an 18-wheeler the effect is about 10%-15% of what it was. The wiggle caused by following in the rear "wash" of an 18-wheeler is reduced to negligible. SumoSprings are the best $350 mod ever!

Another satisfied Sumo customer, sweet!

Put the rears on last week. Amazing difference ,easy install once I jacked it up using jack points. Did not install my fronts yet, looks like need to remove tire. Bilstiens are next. Not sure if that is a diy project or not.

Well, I've had a chance to spend a couple thousand miles in these super sumo springs, and I gotta say I'm pleased with the result. There is very little degradation of the ride but a ton less sway. I also installed the Helwig sway bar and I'm sure it helped as well. My wife said she noticed no change in the ride, but it felt a little choppier on expansion joints to me. It would be interesting to compare the bump stop installation with these super sumos for ride quality and sway effect.

Without upgraded shocks, the Hellwig and Sumos are like a hot dog without mustard. If in doubt, remove one stock shock absorber (its easy) then compress it and extend it by hand. You will find it has minimal resistance in compression as well as extension. After reinstalling it, get on-line and purchase a set or Bilstein or Koni (more $$) shocks for your chassis.

Typcially loaded for a trip, the rear wheels carry about 7,000 lbs. The minimal OEM shocks can't do much to control chassis movement for that much weight. You will find the upgraded shocks are VERY difficult to compress; you have to put your weight into it as opposed to the OEMs - on which you could play polkas if they were an accordion.

I installed a Hellwig Sway bar first, then the Sumos and finally the Bilsteins (Part 24-17702) on the rear of my 15 Solera. Wouldn't be without any of them, and, I think the stock shocks might not even be effective in a sedan.

Miata, thanks for the upgrade info. Where and cost of Bilstein 24-17702 did you purchase? Can not find them on-line. Been hesitant to buy, been getting different products suggestions when searching for my 2015 24R. They suggest Bilstein 24-167161 4600 Series Shock. Good to know that "one of us" has installed and experienced the right shocks and sway bar. Thanks for sharing.

[MiataHoarder]

Away from receipt file at the moment. I believe the cost was around $200 for Bilsteins and the Konis were about $40 more. Mine is a Solera 24S. Google the Bilstein website; they maintain a tech support number who can give you the exact model.

I also have a 99 Dodge 2500 Turbodiesel. Same story on those shocks ... they were made in Brazil ... always been happy with Bilstein products. I'm certain once you remove the original shocks, you'll be happy too.

I believe the correct part number is 24-177702. This appears to be the 4600 series shock that Bilstein recommends. Bilstein also recommends a 19-169163 rear shock as an "OEM Replacement." Or, that's how I read it. You can see their motorhome application guide here:

I've seen the 24-177702 shocks online for somewhere between $75 and $100 per shock.

Are the shocks easy to install?
The rear sumu' were easily installed once I jacked unit up

I replaced the rear shocks with Bilstein 24-177702 . Much improved handling. I already have helwig and sumos front and rear. Rocking when parked virtually gone. Road handling feels more like a large suv. I highly recommend this upgrade.

What Sumo's did you install ? Maxim, Rebel or Solo ?

Thanks !
