PRODUCT DESCRIPTION
TEIN Flex Z Series: High-Quality Adjustable Suspension with Advanced Construction at an Affordable Price
The TEIN Flex Z series is designed for drivers seeking a balance of performance, comfort, and durability without excessive cost. This suspension system offers ride height adjustment, damping force control, and complete mounting solutions, making it suitable for both daily driving and more dynamic use.
Sealed Structure
The shock absorber features a sealed construction where oil and gas are enclosed within a crimped shell tube. This design shortens the production process, allowing for reduced manufacturing costs while maintaining high product quality and consistency.
Twin-Tube Technology
Compared to monotube systems, the twin-tube design provides a longer stroke with lower internal pressure, resulting in increased ride comfort. This construction ensures smoother operation on uneven surfaces, better absorption of road imperfections, and stable performance at both low and high speeds.
16-Level Damping Force Adjustment
FLEX Z is equipped with a 16-step damping force adjustment system that simultaneously controls compression and rebound. Via the adjustment dial, drivers can easily fine-tune the suspension characteristics to suit their personal preferences or driving conditions.
Mounting
Each kit includes mounts specifically designed for the corresponding vehicle model, ensuring a perfect fit and easy installation. In some cases where mounts are not included, OEM mounts are used.
High Durability and Reliability
The suspension components are designed for long-term use in various driving conditions, maintaining consistent performance and reliability over time.
Optimal Dust Boot
A durable dust boot protects the piston rod from contaminants and damage, ensuring smooth operation and extended shock absorber life (in some cases, OEM dust boots are used).
Features
Front Spring Rate: 10 kgF/mm
Rear Spring Rate: 8 kgF/mm
