Description & frequently asked questions
MONO SPORT – Product features and benefits
-
Adjustable damping: Yes, 16 settings
-
Ride-height adjustment: Full-length, depending on axle design
-
Damper construction: Monotube
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.
Monotube construction separates gas and damper oil and is designed for direct feedback and demanding sporty use.
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.
