TEIN Flex Z
Construction and Durability
FLEX Z uses a twin tube damper structure for longer stroke and lower resistance than a mono tube design, giving a comfortable ride over rough or uneven surfaces at both low and high speed. The shell case is finished with TEIN's green powder coating and their patented 2 layer, 1 bake anti rust treatment, along with the ZTP surface coating for extra protection against stone chips and corrosion. Included springs are cold formed from SAE9254 steel with a minimum tensile strength of 200 kgf per square millimeter, and are powder coated to resist sagging and corrosion over time.
Ride Height and Damping Adjustment
The FLEX Z uses a full length ride height adjustment system, so the case length can be changed without affecting damper stroke or spring preload, keeping the impact on ride quality to a minimum. Damping force is adjustable across 16 levels for compression and rebound together, letting the ride and handling be tuned to preference. The kit is also compatible with TEIN's EDFC range, including EDFC5 and EDFC Active Pro, which allow damping force to be adjusted electronically from the driver's seat, with the higher end units offering cornering, acceleration, deceleration and speed reactive control and, on EDFC5, a learning function.
Kit Contents and Service
Each FLEX Z kit includes an upper mount designed specifically for the vehicle, either a reinforced rubber mount or a pillow ball mount with camber adjustment, with some models using OE mounts where no mount plate is available. Rather than a standard overhaul, TEIN offers a replacement service, where the shock absorber body is replaced without needing to return the original unit or remove the vehicle from use for an extended period, and revalving is also available for damping force or stroke modification on request.
