The TEIN FLEX Adaptive Variable Suspension (AVS) for Toyota and Lexus vehicles eliminates the need to replace OE suspension systems with non-OE ones. The FLEX AVS enables ride height adjustment without deactivating AVS. Newly-designed “AVS Needle” for damping force adjustment makes it possible to provide broader damping force adjustable range within the operating angle of AVS actuator.
The TEIN Flex AVS are made with a Hydraulic Bump Stopper (H.B.S) this provides more comfort and height durability at maximum passenger or cargo load. When regular shock absorbers fully stroke, their bump rubbers are compressed. The energy that is generated by that escapes as a repulsive force, which can disturb the vehicle’s behaviour. Furthermore, repeated full strokes can damage the damper. In the same situation the EnduraPro SP KIT, featuring H.B.S., internally convert the impact of the stroke to thermal energy (heat) and absorb it, strongly reducing the impact that disturbs the vehicle’s behaviour. With less damage to the dampers, H.B.S. also contributes to their durability. In shock absorbers with inactive or no H.B.S., the operative valve (green) floats, and oil flows freely through the base valve ports. Resistance to the flow from the shim stack then, causes damping force. Near full compression, when the piston rod strokes beyond a predetermined point, the operative valve is pushed down and activates H.B.S.: the base valve ports are narrowed, blocking the oil flow. This results in high damping force. A relief valve serves to suppress sudden damping force increase, when the pressure in the cylinder exceeds its regular level. The setup of the H.B.S. mechanism is optimized per vehicle model, with the right activation point and damping force.

NOTE:DUE TO INDIVIDUAL DIFFERENCES, INNER FENDER MAY NEED TO BE CUT IF IT INTERFERES WITH THE SPRING. FT/RR: NOT COMPATIBLE WITH VEHICLE WITHOUT AVS. DAMPING FORCE CAN NOT BE ADJUSTED MANUALLY.
