Product Description
PD+ Version: Top Needle, Bottom Circle ● Core Advantages
Stability  | Upper needle, lower round structure The slender, lightweight needle‑shaped piston rod at the top has extremely low inertia, ensuring instantaneous response to road impacts; the larger, circular cylinder at the bottom accommodates more hydraulic fluid, enabling smooth flow and efficient heat dissipation. |
Flexibility  | Back-mounted external nitrogen cylinder The gas cylinder is securely mounted against the cylinder body, resulting in a compact structure and enhanced heat dissipation. This significantly reduces thermal degradation during continuous high‑intensity operation, while also increasing the shock absorber’s stroke. |
Trip length   | 30-stage precision damping adjustment High-precision adjustable valves with a wide soft-to-hard range, effortlessly accommodating diverse needs—from comfortable cruising to firm support. |
| Adjustment Options | Height-adjustable The cylinder body features multiple snap-ring grooves, allowing for free adjustment of the vehicle’s ride height and optimized posture. |
