Description & frequently asked questions
FLEX Z – Product features and benefits
-
Adjustable damping: Yes, 16 settings
-
Ride-height adjustment: Full-length, depending on axle design
-
Damper construction: Twin-tube
Use the adjustment dial to tune damping to your preferred ride. Compression and rebound change together; spring rate stays the same.
Full-length adjustment separates ride-height setting from spring preload on applicable coilover units. Axles with separate springs and dampers use their specific adjustment layout.
Twin-tube dampers support a suspension setup focused on road comfort.
EDFC application assignments are available for this item. Select the specified controllers, motor kits and accessories separately; they are not automatically included.
The vehicle applications for this item specify ride-height values, spring rates, upper mounts and installation notes.
