Adjustable Damper For Seat

Shock Absorber Replacement Steps:

1. Remove the seat cushion.

2. Pull out the lower dust boot fixation.

3. Remove the sleeve (length: 75mm).

4. Unscrew the lower shock absorber fixation bolt.

5. Remove the retaining washer and carefully lever the cable out of its fastening.

6. Re-install the new Adjustable Damper For Seat and all components in the reverse order of removal, ensuring all fittings are secure.

Note: For optimal performance, the interaction between the air bellows, shock absorber, and vehicle springs must be correctly matched to your specific cab type. Always refer to the vehicle or seat manual for detailed guidance.

● Engineered for Specific Vehicle Types:
Each damper is developed with the correct length, capacity, and damping characteristics to perfectly match the requirements of different vehicle models, ensuring optimal performance.

● Rigorously Endurance Tested:
Our dampers undergo extensive testing over millions of simulated kilometers to guarantee reliable function, durability, and a long service life under real-world conditions.

● Critical Replacement Component:
Shock absorbers are wear items. Timely replacement with fresh units reduces stress on the vehicle load, the driver's body, and chassis components, ultimately helping to lower overall operating costs and improve safety.

• Precision manufacturing with strict quality control ensures consistent performance.
• Equipped with larger compression and extension-temperature valves for a wider range of comfortable damping adjustment.
• Provides a soft and comfortable ride, easy to install for non-destructive replacement.
• Filled with high-quality hydraulic oil resistant to both high and low temperatures.
• Specifically designed as a direct replacement damper for ISRI seat models NTS8660/875 & NTS8660/870, among others.

Q1: Is this damper a direct replacement for my seat?
A: Yes, the YSR‑PZ007 is specifically designed as a direct replacement for ISRI seat models NTS8660/875 & NTS8660/870, and fits many other mechanical/air suspension seats with mounting hole spacing between 160–220 mm. Please measure your existing damper length and mounting distance to confirm.

Q2: How do I know if my damper needs replacement?
A: Signs include: excessive seat bounce (especially after bumps), unusual noise, oil leakage on the damper body, or the seat feeling "stiff" with no damping effect.

Q3: Can I install it myself?
A: Yes, basic mechanical skills are sufficient. Follow the 6‑step removal/installation guide in the product section. Ensure the vehicle is on level ground and the seat is unloaded.

Q4: What is the lifespan of this damper?
A: Under normal use, the damper is designed for 3‑5 years or 500,000+ cycles. It is endurance tested for millions of simulated kilometers.

Q5: What warranty do you offer?
A: 12 months against manufacturing defects. Free replacement parts during warranty.

Q6: Do you offer samples for testing?
A: Yes, sample orders (1‑2 units) are accepted. Sample cost is customer‑paid, refundable upon bulk order.
