Do you manufacture custom shock absorbers?

Yes. As 3MG, we manufacture custom shock absorbers according to customer requirements, including special dimensions, custom valve settings, different connection types, and heavy-duty reinforced models.
We provide project-based solutions compatible with OEM numbers, technical drawings, or sample parts.
Are 3MG shock absorbers compliant with OEM standards?

Yes. 3MG shock absorbers are manufactured on high-precision production lines, according to OEM standards, and with special surface treatments that enhance durability.
Why should 3MG shock absorbers be preferred?
Expert manufacturing since 1981

Export to 55+ countries

High durability — Ra0.2 piston surface precision

Long lifespan for heavy-duty use

High-performance testing processes

What should be considered when selecting a shock absorber?
Vehicle type and weight

Operating conditions

OEM number

Trailer design (for trailers)

Connection dimensions

The 3MG technical team provides guidance for selecting the correct product.
What are the signs of a faulty shock absorber?
Excessive bouncing of the vehicle

Loss of stability or grip on the road

Increased braking distance

Reduced control in corners

Oil leakage from the shock absorber

Uneven tire wear

If these signs are present, the shock absorber should be checked.
How often should a shock absorber be replaced?

Depending on usage conditions, it is generally recommended to replace shock absorbers every 60,000–90,000 km. Excessive load, rough roads, and aggressive driving can shorten their lifespan.
Do shock absorbers affect the vehicle's braking performance?

Yes. Weak shock absorbers disrupt the vehicle's load distribution during braking, leading to increased stopping distance. Strong shock absorbers are critical for safe braking.
