After-sales and Modification Market


OEM replacement parts:

The repair market has an essential demand for parts that match the original vehicle’s specifications and performance, ensuring safety and comfort.

Performance Modification:

For off-road and racing modifications, opt for thickened, high-strength, lightweight piston rods to enhance suspension performance and reliability under extreme operating conditions.

Core Features:

It transmits suspension forces, drives the reciprocating motion of the piston, and generates damping to dissipate vibrational energy, thereby determining the shock absorber’s response speed, damping accuracy, durability, and sealing performance.

Key metrics:

High strength (≥980 MPa), high surface hardness (HRC 55–62), high precision (straightness ≤0.15 mm/m), excellent wear resistance, corrosion resistance, and low friction—suitable for high-frequency reciprocating motion and extreme operating conditions.
