Here is a rough translation of the description on the SilkRoad website. This is not 100% accurate. Do not cry if your kit is a little different.

• High pressure gas charged monotube shock absorber with 8 level damping adjustment across a wide range. In addition, the valve design helps to prevent aeration and cavitation even in extreme use.
• Strut type systems use an inverted design, to improve both rigidity and heat dissipation.
• The kit consists of a damper, spring, and upper mount assembly. Strut type (inverted) system includes a pillow-ball upper mount, in addition utilizing aluminium rigid mounts for shocks.
• The coilovers are covered with dust boots to improve durability throughout the use.

This is probably one of the best deals of the century. These coilovers are cheaper than most TEIN sets AND have bigger pistons. They are double height adjustable (preload and bracket height), which means you can lower your car without losing any shock stroke -- no bottoming!! They are 8 way damping adjustable over a wide range. Most kits have camber plates/pillow mounts/rigid mounts... you just can't beat SilkRoad for price vs. performance!
