The Tein Electronic Damping Force Controller or EDFC allows users to easily modify damping force through a control unit and a motor installed in the shock absorber. This controller effectively adjusts your ride's suspension so it quickly adapts to changes on both the road and the track. The EDFC is separated into two products, the Controller Kit and the Motor Kit. Both of which are necessary to properly operate the EDFC. The Controller Kit contains the control unit, a complete wiring harness and all the essential hardware. This kit allows damping force adjustment for both 16 and 32 levels. The maintaining, memory recalling and resetting of damping force levels is also effortlessly accomplished through this kit.

The EDFC Control Unit comes with three suspension presets to allow a quick switch from one setting to the next. Illumination and volume is also adjustable to effectively enhance comfort and visibility for drives during the night or in darker environments. With a compact size, accessing the unit is more convenient and very little space is taken up. Properly setup the Tein EDFC and create a perfect balance between performance and ride quality.
