TEIN Dampers - Street Basis: TEIN Street Basis Damper is the evolution of the popular BASIC coilover model. It incorporates new internal and external components, newly developed coatings and new manufacturing processes.

TEIN engineers have spent many hours developing new seals and internal components to improve durability and product life. This was one of our major goals for the new model. 

Newly developed “ZT” coating for improved durability and hassle-free ride height adjustment. TEIN developed this coating in-house after stringent test and analysis procedures. Our engineers tested different coats, application methods, cleaning processes, etc… in our own brine salt water testing machine which simulates heavy solvents/ road salts used in cold weather climates.

Slip-fit threaded adjustment tube. Allows for damper body and threaded sleeve to be thoroughly coated for rust/ corrosion protection.

The slip-fit allows a more thorough coating on the threaded section as well as powder coated damper body.

Revised Aluminum Spring Seat and Delrin Thrust Washer are light weight and durable. This combination allows for smooth ride height adjustment. The new spring seats have a larger contact surface area and eliminate the need for a rubber spring seat.
