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.

I have a 2004 Beaver 42' Marquis that states there are 10 air bags and 10 shocks. It's the Magnum M10S chassis with the tag axle. Is there anyway to measure the eyelet size to see if it has the (3/4") diameter without removing the shock? Will the bottom and top eyelet have the same diameter? Thanks ( Burt Ross, 05/01/2020 )
Burt, based on your VIN you would use 4 of the 8805-1004SP1 for the front and 6 of the the 8805-1005SP1 for the rear. ( Support )

What is the proper shock number for front, drive and tag on a 2006 Beaver Marquis Roadmaster S series with 10 shocks

( Bill Laatz, 06/13/2015 )


Your 10 bag coach with Roadmaster chassis should take 8805-1004 on the front and 8805-1005 on the drive and tag axles. The SP1 has a larger diameter eyelet size (3/4") so it would be best to verify that bushing size before placing the order.
