Product Overview
The TEIN FLEX Z VSL12-C1AA3 is a complete adjustable coilover suspension kit developed specifically for selected first-generation Toyota Alphard models from 2002 to 2008.
Designed for drivers looking to improve the suspension performance, ride height and handling characteristics of their Alphard, the FLEX Z combines twin-tube damper technology, 16-stage damping adjustment and full-length ride-height adjustment in a complete four-corner suspension package.
TEIN’s UK catalogue confirms this part number for the ANH10W, ANH15W, MNH10W, MNH15W and ATH10W chassis, covering 2.4-litre, 3.0-litre and 2.4-litre hybrid applications.

TEIN’s FLEX Z design uses a twin-tube structure intended to provide sufficient suspension stroke and a comfortable street-oriented ride, while full-length adjustment allows ride height to be changed with little or no change to the damper’s operating characteristics.
16-Stage Damping Adjustment
The FLEX Z features 16-stage damping force adjustment, allowing the suspension characteristics to be altered according to road conditions and driver preference.
The adjustment can be used to tune the vehicle towards a softer road-going setup or a firmer, more controlled response for enthusiastic driving.
Full-Length Ride-Height Adjustment
The TEIN FLEX Z uses a full-length ride-height adjustment system.
This allows ride height to be adjusted while maintaining the damper’s operating stroke more effectively than conventional systems that rely primarily on spring-seat adjustment.
The actual available ride-height range differs between the Alphard chassis and drivetrain configurations. TEIN provides separate adjustment specifications for each application.
Spring Rates
For the main Alphard applications, TEIN specifies:
| Application | Front Spring | Rear Spring |
|---|---|---|
| ANH10W 2.4 FWD | 5.0 kg/mm | 6.6 kg/mm |
| ANH15W 2.4 AWD | 6.0 kg/mm | 6.6 kg/mm |
| MNH10W 3.0 FWD | 5.0 kg/mm | 6.6 kg/mm |
| MNH15W 3.0 AWD | 5.0 kg/mm | 6.6 kg/mm |
| ATH10W 2.4 Hybrid AWD | 5.0 kg/mm | 6.6 kg/mm |
Important Installation Notes
TEIN specifies that the OEM rear dust boot needs to be modified for these applications.
For the ANH15W 4WD application, TEIN also states that the kit is not compatible with vehicles equipped with a side lift-up seat.
These are important points that I recommend including on your product page so customers can check their vehicle before ordering.
