Description & frequently asked questions
FLEX AVS – Product features and benefits
-
Adjustable damping: Electronically through original AVS; no manual adjustment
-
Ride-height adjustment: Full-length, depending on axle design
-
Damper construction: Twin-tube
FLEX AVS retains original Toyota/Lexus AVS functionality on compatible vehicles. Damping is controlled by that system, without manual click adjustment.
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.
H.B.S. adds hydraulic control near the end of compression travel. The specified bump rubbers are still required.
The vehicle applications for this item specify ride-height values, spring rates, upper mounts and installation notes.
