🔖 Feature

☞ Fully Adjustable Shock Absorbers: Featuring 24-stage damping adjustment, these shock absorbers offer dual rebound and damping control, enabling precise tuning for any riding scenario. Adjustable spring preload effectively suppresses body sway.

☞ 24-Stage Rebound Damping for Enhanced Control: Optimize vehicle performance through 24-stage rebound damping adjustment! Set to softest stage for comfortable cruising; Set to 16th stage for spirited driving; Set to the hardest stage for occasional track days.

☞ Independent Ride Height Adjustment: This shock absorber supports height adjustment, enabling precise control over vehicle stance! Lowering range extends up to 1 inch, achieving a lower center of gravity and enhancing sporty appearance.

☞ Twin-tube construction with dust boots: The twin-tube shock design effectively reduces internal friction resistance, enhancing efficiency while maintaining low operating temperatures. This advanced twin-tube technology delivers exceptional handling characteristics for most driving scenarios.

☞ Premium Materials: CNC-machined aluminum top mounts and locking brackets deliver exceptional strength with reduced weight; all bushings feature custom-length rubber sleeves for enhanced shock absorber protection and longevity; aluminum components undergo anodized treatment with anti-corrosion coating, while carbon steel parts utilize powder coating for high strength and durability. The entire product ensures safe and reliable installation.

☞ Spring Stiffness: High-rigidity 55CrSi steel cold-formed coil springs feature front suspension parameters of 10 kg/mm (560 lb/in) and rear suspension parameters of 8 kg/mm (448 lb/in). After enduring over 600,000 consecutive cycles of testing, spring deformation remains below 0.04%, ensuring exceptional tensile strength.

☞ High-Viscosity Index Shock Absorber Fluid: This specially formulated lubricant maintains stable damping performance and smooth operation across a wide temperature range. It ensures driving stability and comfort remain unaffected by significant temperature fluctuations during vehicle operation.

🔖 Note

① All aftermarket parts must be installed by certified technicians and comply with local modification regulation.

② Before and after installation, ensure all components are tightened to the correct torque specifications (refer to the vehicle maintenance manual for details). Any loose nuts, bolts, or fasteners may cause abnormal noises. Inspect and retighten promptly to prevent serious issues.

③ Impact wrenches are strictly prohibited during installation to prevent product loosening or damage.

④ Verify clearance between tires and suspension components, ensuring a minimum clearance of 4mm. Add wheel spacers if clearance is insufficient. Note: Torque beam rear suspension systems cannot meet this requirement.

⑤ Regular maintenance of adjustable shock absorbers is recommended. Spraying WD40 every 3 to 4 months keeps components smooth and clean, effectively extending their service life.
