SHOCK ABSORBER MANUFACTURER
GDST manufacture a wide range of twin-tube shock absorbers and monotube shock absorbers in various sizes, mounting configurations, spring rates, and valve options, all of which can be adjusted to suit your application. Our extensive product range enables you to select the ideal product to provide optimum performance for you and your customers.
Our shock absorbers are of the same quality as K.Y.B and O.E.M, all are shock and strut manufacturers in the world. A leader in shock absorbers technology for more than 20 years, we produce more than 4000 models. GDST is building its South American reputation on this tradition of consistent quality, advanced technology, and competitive price.
GDST Shock Absorbers are uniquely designed for smooth performance, durability, and driving stability in all weather conditions. Each shock absorber is nitrogen charged to eliminate aeration which improves driving and handling performance. GDST’s Twin Tube Design includes nitrogen gas charging to keep the shock absorber cooler and to extend its service life. A sturdy aluminum alloy piston and high-quality oil seal add to the overall durability.

Types of Shock Absorbers
There are two types of shock absorbers for vehicles: the twin-tube shock absorber and the mono-tube shock absorber in the GDST shock absorber factory. There may be some variations between shock absorber models depending on the vehicle type. However, any shock absorber will either be a twin tube or a mono-tube.
Twin-tube Shock Absorbers

2. Gas Compartment
3. Equalizing Chamber
4. Absorber Tube
5. Guide/Outer Tube

5. Rebound Stop Spring
6. Absorber Tube
7. Piston
8. Bottom Value
A twin-tube shock absorber could also be referred to as a two-tube shock absorber. This is because it contains two cylindrical tubes. The inner tube, called the working tube or pressure tube, creates the hydraulic pressure most. There is, however, an outer tube called the reserve tube. The reserve tube will function when the velocity of impact is high, and there is a need for high pressure.
Mono-tube Shock Absorbers
Mono-Tube Absorber
1. Piston Rod Guide
2. Absorber Tube
3. Piston Rod
4. Rebound Stop
5. Working Piston
6. Dividing Piston
7. Gas Compartment

11. Rod Guide
12. Bump Stop
The mono-tube shock absorber is an advanced invention. This has only one tube – the pressure tube. However, it has two pistons. The working piston and the dividing or floating piston move in synchrony to cause hydraulic pressure. Mono-tube shock absorbers generally tend to be more efficient. They will, however, not fit into vehicles designed for twin-tube shock absorbers.
When it comes to production material, rubber shock absorbers are the most common. Essentially, they are very durable, have high elasticity, and eliminate vibration readily. They also withstand shock more and offer sound insulation. Rubber shock absorbers are also better dampers. Nevertheless, there are shock absorbers made from metal.
Comparative Analysis of Component Quality
- Stamping Parts
- Pipe Fittings
- Oil
- Oil Seal
- The Guide Assembly
- Buffer Ring
- Piston Bottom Valve and Fittings
1. Stamp Part - Material
High Quality
GDST: Original cold rolled coils from Bao Steel or Benxi Steel
Ordinary
Other factory: Unknown
Notice: The thin stamping part material is easy to cause the product deformation and the joint loosening, which seriously affects the driving safety.
2. Pipe Fittings - Working Cylinder
High Quality
Working Cylinder of GDST:
Hot coiled cold-rolled welded drawn tube from Benxi Steel Group or Meishan Steel
Ordinary
Working Cylinder of other factory:
Welded Rolled Pipe
Pipe Fittings - Out Pipe
High Quality
Outer Pipe of GDST:
Hot coil Q235B/SAE1022 welded pipe from Bao Steel or Benxi Steel
Ordinary
Outer Pipe of other factory:
Band steel from small factory
Notice: The tube billet produced by small factory is easy to cause mechanical accidents such as cracking, bending, deformation and so on because of unstable material elements and unstable welding process.
3. Oil of Shock Absorbers
High Quality
Oil seal of GDST: NOK/NAK/RFX
Ordinary
Oil seal of other factory: unknown
Notice: Inferior shock absorber oil is easy to deteriorate. The viscosity varies greatly at high and low temperatures, resulting in a great difference in the shock absorption effect between high temperature and low temperature. Inferior oil is easy to have a short service life and is easy to produce abnormal noise.
4. Oil Seal
High Quality
Oil of GDST: NISSEKI/SHANGHAI HIRI SV-3
Ordinary
Oil of other factory: unknown
Notice: The oil seal of non-big-brand factory is easy to cause early oil leakage, gas leakage, short service life,abnormal noise and so on.
5. The Guide Assembly
High Quality
Guide Bushing of GDST: Red Abrasion Resistant Teflon
Guide of GDST: Iron Powder Metallurgy, One-time Forming
Ordinary
Guide Bushing of other factory: Black Ordinary Teflon
Guide of other factory: Iron-base Powder Metallurgy, Pressing Molding, and Machining.
Notice: It is easy to deform and crack when the strength of the inferior guide is not enough. The inner surface of the inferior guide bushing is more likely to wear out and causes early product failure.
6. Buffer Ring
High Quality
Buffer Ring of GDST: NBR
Ordinary
Buffer Ring of other Factory: Plastic
Notice: The plastic buffer ring is not resistant to oil and fragile after impact, the impact sound is heavy, and does not act as a buffer.
7. Piston Bottom Valve and Fittings
High Quality
GDST: Powder Metallurgy & Auto-Screwdriving Machine
Ordinary
other Factory: The iron plate is easy to rust, resulting in oil deterioration and valve rust death, resulting in premature failure of the product and unstable force value.
