i have a mm spartan 1260 rayco granning ifs front axle, which koni would fit..would it ride better then the oem blisteens ( carl bethmann, 11/21/2023 )
The Koni 90-2815's SHOULD be correct for that front suspension. They will definitely ride better than Bilsteins due the Koni's being strictly hydraulic, not high gas pressurized like  Bilstein.  Koni's control the "rebound" but allow the suspension to  "soak up" the impacts, rater than resist compression . It is a good idea to verify the mounts and dimensions listed on the product page.  ( Support )
I have a 2002 Newmar Mountain Aire 4096.
I have the IFS 1370 Spartan Chassis.
Looking for your recommendation for new front and rear shocks to smooth out porpoising to improve overall ride. Thanks in advance, Ron ( Ron Tharaldson , 05/27/2023 )

Hello Ron, the 90-2815's should be correct for the front based on your information, the rears should be the 8805-1009 Koni FSD's . Please check the notes on the product page about lower mounting bolts.

I HAVE A 03 DUTCH STAR SPARTAN IFS 1200, IT CALLS FOR THE 90-2815 ADJUSTABLE KONI WHICH I LIKE THE ADJUSTABLE BUT WOULD THE 99B-3234 GIVE MORE CONTROL OF THE PORPOISING. THEY ARE A BIT SHORTER BUT HAVE THE SAME MOUNTS. ( WALLY EATON, 03/16/2023 )
Hi Wally, there could be interference at the lower mount with the 99B-3234's, as the 90-2815 has a slightly extended lower eyelet . I would recommend sticking with the adjustable and set them to 3/4 of the way tight, that will allow for future adjustment to compensate for wear , and control the rebound/porpoising .  ( Support )
2003 Newmar Essex K2 IFS 1370....I am pretty sure I need the KONI 902815 for the front, Drive ...Reyco 240 AR ..it looks like 8805-1009 Rear

Hello Alan , those are correct shock #'s for that VIN , the tag takes 8805-1013 Koni's  ( Support )
I have a 2004 Newmar Dutch Star on a Spartan Mountian Master Chassis

According to Spartan, I have a IFS1370HP, Axle Serial # 972117, Tuthill Front Axle. May be a typo on Spartan's part ?

The 90-2815 only goes up to a IFS1360. I far as I can see the next shock available is for the IFS 1400 series.

Will the 90-2815 work on my rig ? ( Michael Snyder, 02/01/2021 )
Hi, I contacted Spartan to verify that your coach calls for the Koni 90-2815 on the front end. ( Support )
What koni shock should I use for a IFS 1200, 1997 dutch star by newmar 38 ft rv ( victor moreno, 10/11/2016 )
