Koni 8805-1009

Description:

Koni Frequency Selective Damping (FSD) shock absorbers provide superior handling characteristics without compromising ride comfort. The FSD is firm where you need it, such as through corners, but rides soft over expansion joints and rough roads. A special valve filters out annoying vibrations before they enter the vehicle, resulting in a smooth ride over a variety of road surfaces.

Special Note: We have seen a limited number of Spartans and PowerGlides that use a 5/8" lower shock bolt instead of the standard 3/4".

You can see if you need the bushing set by checking if an 1-1/8" wrench fits snug on the head of the lower shock bolt.

If it DOES fit then you DO NOT need the bushing set,

If it is smaller then you would require the bushing set.

If you need the bushing set for your chassis you can purchase a 3/4" to 5/8" steel bushing here: 3/4-5/8-BUSH

I did the 1 1/8" wrench test and it was not snug. So does that mean I need the 16ea. spacers for rear shocks? The shocks for front are the 99B-3234 are this the new upgraded model? The back are 8805-1009 correct. Thanks ( rc thomas, 03/03/2024 )

Yes, if the wrench did not fit tight then you will need the spacer kit, you just need to order quantity 1 to do the lower bolt on each side. 99B-3234 is the new EVO model shock for your application.

Will an oversize Koni fit on my Spartin chassis . I have a 2019 entegra Aspire, the original buyer quickly installed larger Koni shocks on the front but not the rear. Is this a ride problem as far as porpoising is considered or maybe he did not do the rear because in just looking at the front Konis and then observing the amount of clearance between shock and the frame member it seems as a maybe fit at best for the larger Koni? I,m looking at maybe a half inch. ( John Pepper, 10/01/2022 )

Hello John, the the larger diameter Koni "90 Series" are for front applications, primarily for Independent front suspensions, which place more leverage on the shocks and need more damping due the increased leverage. The 8805-1009's are the "FSD" design and work well on the rear application as they are "self adjusting" too give control when needed and still provide good ride quality . ( Support )

Looking for larger size shock than standard on my 2019 entegra Aspire 40 foot. More like the 60MM size, Will they fit? ( John Pepper, 09/26/2022 )

Koni 99B-3234 front and Koni 8805-1009 rear will fit your Entegra Aspire. ( Support )

I have a 2013 Tiffin Phaeton 36GH. I think she requires 2ea 99B3209 shocks for the front and 2ea 8805 1009 shocks for the rear. Can you verify or correct this information? ( Bill Milman, 09/02/2022 )

Your coach will take the 8805-1020 front shocks and 8805-1022 rear shocks. ( Support )

Can you tell me the procedure for adjusting the KONI front (9005 1098) and rear (8805 1009) shock absorbers to make them stiffer? ( James Rodda, 09/25/2021 )

Both of these shocks use Frequency Selective Damping (FSD) technology which is an automatic adjusting of the shock to different road conditions. They do not have a manual adjustment option. ( Support )

I want to verify the correct part number for my motorhome. It is a 2004 Newmar Dutch Star on a Spartan Mountain Master chassis.

Do you have the shocks in stock?

Thanks,
Don ( Don Massey, 06/28/2021 )

The front part # is 90-2815 and the rear is 8805-1009. ( Support )

Can the Koni EVO 99B-3262 for the front and the Koni 8805-1009 for the rear, be installed on a 2015 Tiffin Allegro Bus w/Powerglide Chassis? If the Koni 8805-1009 can be used, I am not sure at this time whether or not the 3/4" to 5/8" steel shock bushing kit will be required, if ordered, but not used, is it returnable? ( Gary Bell, 07/08/2020 )

Yes, these should be the proper shocks. If you end up not using the bushings, they are returnable. You would just be responsible for return shipping. ( Support )

2016 Allegro Bus
Do you have a projected availability date for Koni 8805-1009? ( Norm Scherer, 10/12/2019 )

We should have these back in stock by the last week of October, maybe sooner. ( Support )

Good morning, I live in Sunshine Coast Queensland Australia, and although my Tiffin Allegro Breeze is a 2014 model, it has the I beam front suspension, they didn't release the independent front suspension in Australia until around 2016. Question 1: Are the correct Shock Absorbers, Front 8805 1018 Rear 8805 1009. Question 2: what is the cost of freight to ship to Queensland Australia. Question 3: Can they be purchased here in Australia to save on shipping cost, and if so can you give details of a supplier here. Kind Regards Jeff ( Jeff Charles, 04/13/2019 )

Those appear to be the correct part #'s based off description but I would want to verify by getting the part #'s off your existing shocks or the compressed and extended lengths. I do not know of any Australian importers for Koni so I think you're stuck with ordering from us. ( Support )

Hi, I live in Sweden and I am looking for KONI FSD, for my 12 tons motorhome. at IVECO chassi. and wonder if you have this model with pins ( the front dampers have pin up and down and the rear dampers have only pin upside. If not I can do an adapter.

And I wonder what you have for delivery time to Sweden of this parts.

Please let me now.

Best Regards
Mr Bo Weidar

We do not have an application sheet for European vehicles. I would suggest contacting Koni Holland directly for assistance. ( Support )
