UMI Performance Rear Viking Shock Assembly (6569) - 2015-2027 Ford F-150 2WD/4WD
Restore ride quality and gain extensive suspension tuning capability on your lowered 2015-2027 Ford F-150 with the UMI Performance Rear Viking Shock Assembly. Built around the Viking D220 double-adjustable shock, this rear damper package provides independent compression and rebound adjustment while including the UMI-specific spacers and hardware required for proper installation on the F-150.
Designed for significantly lowered trucks, including F-150s equipped with a rear flip kit such as the UMI system, the Viking D220 gives you the ability to fine-tune the rear suspension for improved ride quality and a more performance-oriented feel. With 19 compression settings and 19 rebound settings, the shock can be adjusted to suit street driving, performance use, and individual vehicle setups.
Viking D220 Double-Adjustable Shock
The heart of the UMI 6569 assembly is the Viking D220 double-adjustable shock. Independent compression and rebound adjustments allow you to change how the rear suspension responds during compression and extension instead of relying on a single fixed damper calibration.
Whether the goal is improving the ride of a lowered daily driver or dialing in a more performance-focused suspension setup, the extensive adjustment range provides the flexibility needed to tune the truck for its intended use.
19 Compression and 19 Rebound Settings
Each Viking D220 provides 19 positions of compression adjustment and 19 positions of rebound adjustment. These independent controls make it possible to fine-tune rear suspension behavior to balance ride quality, handling, and performance.
The adjustable design is especially beneficial on substantially lowered trucks, where properly matched damping can make a significant difference in how the rear suspension responds on the street or during performance driving.
UMI-Machined F-150 Spacers
UMI includes four machined spacers with each shock assembly to adapt the Viking D220 bushing width properly for the Ford F-150 application. These vehicle-specific spacers eliminate the need to source or fabricate separate mounting spacers when installing the shock.
Installation Hardware Included
In addition to the Viking D220 shock and four UMI-machined spacers, the assembly includes the proper mounting hardware for installation on the rear of the F-150. The complete assembly is designed to provide the components required to properly fit the Viking damper to the truck.
Designed for Lowered F-150s
The UMI 6569 Rear Viking Shock Assembly is specifically intended for substantially lowered trucks rather than stock ride-height applications. It can be used on trucks equipped with a rear flip kit, including the UMI rear lowering system, or on vehicles meeting UMI's minimum lowering requirements.
For 2WD F-150 applications, UMI specifies a minimum rear drop of 3.5 inches. For 4WD applications, the truck must be lowered a minimum of 5.5 inches when the shock is not being selected as part of an appropriate flip-kit configuration.
Street and Race Proven
The Viking D220 and UMI installation components provide a street and race-proven rear shock solution for lowered F-150 builds. Extensive damper adjustability allows the suspension to be tuned for a comfortable street-oriented setup or a firmer, more performance-focused response.
