Advantages of Birkom Custom Made Shock Absorbers

Pay more attention to the safety of drivers and cargo

The Birkom custom shock absorbers can quickly attenuate the vibration generated by the vehicle during driving, thereby improving the ride comfort of the vehicle; the air shock kit is beneficial to protect the body of the driver and the occupant, the long-distance driving is not easy to fatigue, and the comfort is also improved. Ride comfort and safety in driving. Also these adjustable air shocks can be manually filled. Our shock absorber wholesale can effectively protect the goods transported on the vehicle from being easily damaged and is suitable for high-speed and long-distance transportation of passengers and vibration-resistant goods such as hazardous materials, electrical equipment, and precision machinery.

Custom Shock Absorbers

The surface of the air suspension shock absorber piston rod is subjected to high-frequency quenching, surface micro-crack chrome plating and super-precision longitudinal polishing to ensure smooth contact between the piston rod and the oil seal, extending the life of the oil seal and thus extending the life of the product.


Air Shocks

Birkom’s world-class quality oil seals use high-quality oil seals to reduce friction between the piston rod and the oil seal, and extend the life of the oil seal and product life. With the unremitting efforts of the technical team, we have overcome the problems of China’s wide-ranging temperature difference, altitude change, dry and wet changes, and developed our own oil seal, patent number: (2018200086735), the oil seal with multi-lip design can effectively seal oil Liquid, high-pressure nitrogen, isolate external dust and dirt, to ensure air shock suspension product quality and life.


Air Shock Absorber

Birkom uses American imported brand piston rings, which have excellent wear resistance and effectively prevent damping attenuation. It ensures close contact between the piston and the working cylinder wall, eliminates oil leakage between them, and obtains a stable damping force.


Air Shocks for Trucks

Birkom high-performance shock absorber oil, using high-quality shock absorber oil is very good in anti-foam and anti-shear. Reduce the cost of shock absorbers product idle travel and wear of internal valve system parts, and long product life. The shock absorber has excellent temperature/viscosity performance and is suitable for the normal use of vehicles in different regions and climatic conditions.


Air Shock Kit

The three major powder metallurgy parts of Birkom air shocks for sale are all produced by well-known manufacturers, and the test parameters are better than those of similar international product factories. The piston of Birkom has been promoted to research again on the basis of the first generation of American and European designs, and finally in December 2016 the design of air shocks for towing was completed by the end of the month. The second-generation valve system is specifically designed for a variety of road conditions and customer needs, effectively responding to bumpy road conditions and slowing down the rapid rise in temperature. Further improve the durability of the custom shock absorbers.
