Our Shock Absorbers
A shock absorber is only as good as what it’s made of. That’s why we insist on high-quality materials in every piece we produce, delivering stronger durability, more stable damping, and fewer quality issues for our aftermarket partners.
- High-Strength Piston Rod
We use medium-carbon steel piston rods, finished with micro-crack hard chrome plating, to deliver strong wear resistance and reliable corrosion protection, ideal for long-term aftermarket use. - Sealed with Original NOK Oil Seals (Japan)
Equipped with genuine NOK oil seals, our shock absorbers are designed to minimize oil leakage and keep damping performance stable mile after mile. - Seamless Working Cylinder Construction
Our working cylinder is made from precision seamless steel tubing, providing better strength, smoother internal movement, and resistance to deformation. - Precisely Tuned Damping Valve System
Our optimized valve design ensures balanced compression and rebound force, helping vehicles stay stable while improving overall ride comfort. - Filled with NISSEKI Shock Absorber Oil
We use NISSEKI high-performance shock oil for its excellent anti-foaming properties and consistent damping performance across a wide temperature range.

FAQ of Shock Absorbers
what is a shock absorber?
A shock absorber is a key suspension component designed to control vehicle movement by reducing vibration, bounce, and impact from the road. A car shock absorber or truck shock absorber helps keep tires in contact with the road, improving stability, handling, and driving comfort. In the automotive aftermarket, shock absorbers are commonly replaced as part of regular suspension maintenance.
how long do shock absorbers last?
On average, aftermarket shock absorbers last between 50,000 and 100,000 kilometers, depending on driving conditions, vehicle load, and road quality. Heavy duty shock absorbers used in trucks or commercial vehicles may wear faster under high loads or rough roads. Regular inspection helps determine the right time for shock absorber replacement before performance declines.
how do shock absorbers work?
Automotive shock absorbers work by converting kinetic energy from suspension movement into heat energy, which is dissipated through hydraulic fluid. Inside most hydraulic shock absorbers, a piston moves through oil-filled chambers, controlling compression and rebound. This process limits excessive movement of the suspension, ensuring smoother handling and consistent performance in both front shock absorbers and rear shock absorbers.
signs of a bad shock absorber
- Excessive bouncing after bumps
- Reduced steering control or vehicle instability
- Uneven or accelerated tire wear
- Oil leakage from the shock body
- Longer braking distance
Worn shock absorbers can affect overall suspension balance, making timely replacement essential for safe driving and customer satisfaction.
Shock Absorber Factory
Founded in 2001, our shock absorber factory spans 50,000 m² and is equipped with dedicated facilities for stamped parts and piston rod production. With advanced production lines and complete testing equipment, we ensure every autombile shock absorber meets OE standards and support you stable supply with a monthly production capacity of 100,000 pcs . Our factory is certified with ISO 9001, IATF 16949, and CE, guaranteeing reliable performance and safety.
How We Produces OE-Quality Shock Absorbers?
Strong manufacturing. Reliable performance. Consistent quality.
Material Selection&& Tube Processing
We use high-strength alloy steel & seamless tubes to ensure cylinders maintain shape under high pressure.
- Precision cylinder production: Cold-drawn and ultrasonically inspected to ensure zero micro-cracks.
- Reinforced piston rods: treated with medium-frequency quenching to achieve HRC50-60 for exceptional fatigue resistance.
Core Piston Rod Technology
The piston rod determines the shock absorber’s response speed and smoothness.
- Multi-stage grinding: CNC grinding achieves a mirror-smooth surface with Ra≤0.05µm
- Micro-crack chrome plating: Stores lubrication film, reduces friction, and extends seal life.
Fully Automated Digital Welding
Strong welds are critical to vehicle safety.
- FANUC robotic welding: Ensures consistent, full, and pore-free welds on bases and spring seats.
- Penetration monitoring: Destructive testing on each batch ensures welds withstand extreme shear forces.
Clean Assembly Environment
- Multi-stage ultrasonic cleaning: Every component is thoroughly cleaned before assembly.
- High-purity nitrogen filling: 99.9% pure nitrogen prevents hydraulic oil foaming and ensures consistent damping.
- Premium seals: Imported NOK or equivalent multi-lip oil seals guarantee zero leakage from -40℃ to 120℃.
Advanced Surface Protection
Electrophoresis & powder coating: Eco-friendly corrosion-resistant coatings withstand 240–480 hours of salt spray tests, keeping every piece durable and visually flawless.
Rigorous 100% Performance Testing
We don’t rely on sampling; every piece is tested.
- Damping force testing: High- and low-speed performance is measured on computer-controlled test rigs with a strict ±5% tolerance.
- Durability testing: Simulated 5 million-cycle tests ensure long-term performance without loss of damping force.

Your challenge VS Our solution
We understand your challenges, so we’ve built solutions for you
Your Challenge
- Difficult Communication With Suppliers
“I frequently need to repeat my requests, yet many suppliers still respond unclearly or too slowly. Updates on orders are often missing, communication is inconsistent, and misunderstandings happen regularly, causing delays, mistakes, and wasted time on my end.”
- Delivery Delays and Broken Promises
“Delivery delays are a constant problem with my old supplier. The delivery date gets confirmed, I arrange my plans, and then right before shipment, it’s delayed again. This causes all kinds of trouble on my end, upset customers, rushed explanations, and damage to my reputation, even though I didn’t do anything wrong.”
- Receiving Low or Unstable Quality Products
“Some parts simply aren’t finished well enough. Poor sealing and rough machining have led to oil leakage after installation. Once that happens, customers come back with complaints, request returns or refunds, and I have to cover the cost, even though the problem started with manufacturing quality.”
- Poor After-Sales Support
“When problems happened, it felt like my supplier disappeared. I kept chasing replies, but nothing moved forward. In the end, I took the loss, dealt with customer complaints, and tried to protect my reputation on my own.”
