Twin-tube Shock Absorber

Nitrogen gas in the tube reduces the aeration or foaming that commonly deteriorate the performance of the shocks.

Strut Cartridge

ADD cartridge can control the impact of springs, and control the accuracy of wheel position in driving state. The durability of cartridge offers maximum vehicle grip and stability.

Shock Absorber With Spring seat

Shock absorber with spring seat uses high quality materials to make the seat bearing the spring, and combines with the structural features of strut cartridges to prevent breaking and leaking. It takes various measures to promote durability and driving experience.

Strut

Strut uses high quality materials to make the seat bearing the spring, and integrates the mounting bracket into the body of the shock absorber in compliance with the suspension fixing requirement structurally, and makes the damping force more concentrated on the path of vertical movement of the coil spring.

Airbag Shock Absorber

ADD airbag shock absorber is mounted with the telescopic valve in front of the working cylinder, rolling on the double shells outside the working cylinder, and is used for the purpose of position fixation and limitation. Compressibility of the airbag can be used for balancing the compression and extension damping force. The consistency of shock absorber’s damping force is good; and the applicable adjusting range of damping force is wide.

Strut Assembly

ADD launched M series of suspension strut assembly timely based on the market development and demand. It integrates coil spring, dust cover and spring seat all together so that the user can change the complete assembly conveniently and easily.

Steering Damper

ADD steering damper series can reduce steering vibration and relieve drivers’ fatigue in all road conditions, providing higher driving performance. Besides, those components can reduce wears and tears of tires and premature aging of front components.

Adjustable Shock Absorber

A shock absorber series, by using advanced technology such as adjustable screw on spring seat, variable damping technology, and magneto-rheological technology, realizes individualized setting of shock absorbers and suspension system according to different demands of drivers.

Cabin Damper

ADD cabin damper is installed between the cabin and chassis of commercial vehicle, and is used for the purpose of buffering the vehicle vibration for the second time. Cabin damper is economical and is an ideal component for heavy-duty vehicles.
