Koni 8805-1001


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.

We would want to verify with VIN but the part #'s you should need for a 2008 W-series is 8805-1001 for the front and 8805-1002 for the rear. ( Support )

Spec say I have 2009 Workhorse W16 chassis.
Tried 8805-1001, but Front and rear Shocks have eyelets on both ends.
Do you know which model is correct?
( Phillip Cain, 01/22/2021 )

Unfortunately, Koni does not make a shock for the 2009 or later W16 chassis.

Is the $160 price for one shock? ( Larry Powers, 06/03/2017 )

Hi Larry,

These Koni shocks are $160 each.

Just received these shocks last week and noticed there was no mounting hardware in boxes. ( Front ) Do you use existing rubber from the old shocks when mounting the new ones? Thanks. Garry. PS The front shock boxes had been open but the rear shock boxes were sealed.

( Garry Shaw, 03/28/2016 )


The 8805-1001 does not require any additional hardware or bushings, they are pressed in. The only thing you will reuse is the nuts, bolts and washers.

will these fit on the front of a 2002 Itasca suncruiser 35U

( dave, 08/18/2015 )


As long as your VIN starts out "5B4MP67G..." then these are the correct front shocks for your coach.

l have a 2005 Gulfstream Sunvoyager on a workhorse chasis . I want to replace the front and rear shocks. What are the correct shocks for my RV. Thank You

( Larry Berge, 06/07/2015 )


All Workhorse W-Series (5B4MP) take the 8805-1001 on the front. 2004 model year was a split year on what rear shocks it requires, either 8805-1002 or 8805-1003. What you need to do is look at the style of mounting the rear shock uses both top and bottom. If the shock has pin or stud type on top and bottom then it takes the 8805-1002. If it has an eyelet on top and pin on bottom then it's the 8805-1003.

I have a 1995 southwind motorhomwe on a Ford chassis. It is a class a 32' long gas motor. I want to replace both front and rear shocks. I am looking at Koni or Billstein. What are the right shocks for my vehicle.

( john, 05/06/2015 )

You definitely should go with the Koni's, you won't be sorry. The front part # for your chassis is 8805-1018 and the rear part # is 88-1668SP1.
