LTB Autosports currently has them for $131.04 w/ free shipping.

Not sure how accurate the picture on Amazon is but it shows a MacPherson strut for that P/N.

I couldn't find a price at the Sprinter Store site.

So everyone agrees with changing rear to Konis?
This helps bounce and sway?

Smile Thank You Everyone!

Thank you fellow RVers for your input. I love this community; people are so helpful. It sounds like Koni Rear Shocks for sure. For those who want to respond to my original question, please feel free to do so. The more information, the better.

FWIW, I put the Koni shocks on the back and Koni struts on the front.

From what Ive seen, some folks jump in with both feet. Some just swap out the rears. Some jump in the deep end and change out everything suspension related.

My experience with modifying high performance cars, esp. race cars is to change one thing at a time so one gets a sense of how it changes the feel. If you do everything at once, it will be be very hard to determine which part made what difference and how.

That said, I will be upgrading the fronts very soon. Then again Im a bit more sensitive to suspension changes. Im sure most will be fine with just the rears, but I feel the difference in roll characteristics from rear to front. When a truck passes me or I get hit with a gust of wind, the rear is nice and controlled but the front reacts by being pushed over more harshly while experiencing more front body roll.

Well in that thinking of a little at a time I just ordered Konis for the rear.

Let's see how that goes.

Ok now I am convinced and order the Koni's form the Sprinterstore for the rear and will try to install them myself. My MB-Sprinter Service quote me $750.00 to change the rear shocks. guess everything is a little more expensive at MB.

Fixed it for you.

I did install SUMO spring-support in the rear first and only notices a mild difference. It still would move but without an after shock or sway.

Now installed the rear Koni and did the adjustment myself 75% of max which worked well. Sway is reduced but as Mario experienced the front still fells a little wobbly.
They really install easy.

Now I did order the front Koni and the front Sumo spring-support.
I am still wondering if I should ad the sway bar and which one.

Anybody any ideas?

Not sure heavier sway bars will help ride comfort. Also the Sprinter Store just announce, on the Sprinter-forum, that they now have new 7-leaf rear springs for our 3500 Sprinters. I'm considering them along with new Koni shocks when is stop there next month. Have call them for pricing.

More food for thought.. I installed all four Koni shocks, the sway bar and the spring assist kit, all from the Sprinter store. I will say that the spring board effect seems to be gone, however as Protag mentioned the ride is very firm. I've been thinking it was due to the spring assist kit but after reading Protags comments (he didn't install the spring assist kit) perhaps it is the firm Konis. The handling around curves and pulling a heavy trailer is very good. One more advantage to the spring assist kit is that it will raise the rear of the van back to it's original stance as it was before Airstream added their equipment. The spring itself is about an inch and it's added support of the existing springs will add another inch giving you a total lift of around two inches. You could always skip the spring assist, give it a try and add it later. I think as someone else mentioned, the real solution is an air ride suspension and at this point there doesn't seem to be a good source.

One more thought. I checked on the Sprinter store website and they do have a new shock available for the Sprinters that is supposed to address the harsh ride. This may be a great option for you. Forgive me if this has already been discussed. The following verbiage is from the Sprinter store site.

Koni NA and the Sprinter Store teamed up to bring Koni's FSD technology to the Sprinter world. You cant find a better shock for your motorhome than FSD: KONI frequency selective dampers. We have combined the benefits of performance and comfort into one shock absorber. FSD is firm for control over large bumps and corners, but soft for comfort over expansion joints and rough roads. While KONI is known to reduce bouncing in motorhomes, our FSD shocks include a special valve that filters out annoying vibrations before they enter the coach. The result is an incredibly smooth ride, with plenty of shock left to control pitching and swaying.

For those of you who have done the Koni shock upgrade: I replaced mine and also added the spring assist kit, after doing so I felt the ride was too firm for my liking but wasn't sure if it was the shocks or the spring assist kit. I spoke with Foster from Upscale auto/Sprinter store yesterday, he assured me that the ride is due to the shocks and said they set them very firm before sending them out. He suggested that I back them down to the softest setting and go from there. He says it will soften the ride but will still far out perform the factory shocks. He said the new FSD shocks are the all around best but since I've already dropped the cash on the standard Konis' I'm going to try and get the desired ride from them. More to follow!
