Heavy-Duty Rear Shock Upgrade – KONI FSD for Monaco & Holiday Rambler with 8 Air Bag Suspension

Improve the ride and handling of your diesel motorhome with the KONI 8805-1017 Frequency Selective Damping (FSD) Rear Shock, designed for Monaco, Holiday Rambler, and Beaver Class A motorhomes built on the Roadmaster RR8R / RR8S chassis. These premium KONI FSD shocks are engineered to improve ride comfort, suspension control, and highway stability—especially important for air suspension diesel pusher motorhomes.

KONI Frequency Selective Damping (FSD) technology automatically adapts to changing road conditions. The shock remains firm during heavy suspension movements such as cornering, braking, or uneven pavement while softening over expansion joints and rough roads to provide a smoother ride.

A specialized internal valve system helps filter harsh road vibrations before they reach the chassis, improving driver comfort while maintaining excellent suspension stability. The result is reduced rear-end bounce, improved chassis control, and better overall ride quality.

If your coach experiences harsh ride, excessive rear-end bounce, or poor highway stability, upgrading to KONI FSD shocks is one of the most effective ways to improve ride comfort, handling performance, and driver confidence.

Product Benefits:

Frequency Selective Damping automatically adapts to road conditions
Improves ride comfort without sacrificing suspension control

The KONI 8805-1017 FSD rear shock is designed for Monaco, Holiday Rambler, and Beaver Class A diesel motorhomes built on the Roadmaster RR8R and RR8S air suspension chassis. These premium diesel pusher chassis rely on properly controlled suspension to maintain ride comfort and highway stability. This shock helps reduce rear-end bounce, improve chassis control, and deliver a smoother ride compared to factory shock absorbers.

Specifications:

Collapsed Length	Extended Length	Upper Mount	Lower Mount
13.70"	22.13"	Stem	Eye 1/2"

Special Notes:

Sold individually.
This shock uses a vertical stud (stem) upper mount and eyelet lower mount.
If your coach uses eyelet top mounting, use KONI 8805-1005 instead.
Many Roadmaster chassis use one shock per airbag, meaning up to four rear shocks may be required.
Verify mounting configuration before ordering.

Other Information:

Q: What is KONI Frequency Selective Damping (FSD)?
A: FSD technology automatically adjusts shock damping based on road frequency, providing firm suspension control during heavy inputs while softening over expansion joints and rough pavement.

Q: Why do some motorhomes require multiple rear shocks?
A: Many Roadmaster air suspension chassis use one shock per airbag, which can require up to four shocks on the rear suspension for proper ride control.
