One of the main reasons we hooked up with TCS / Race Tech was because they operate their business just as we do. They personally build each and every shock to order based on the riders specifications. This way you know that your shock is setup specifically for you. Unlike other shock companies that have generic shocks sitting on the shelf (if you are lucky, or unlucky depending on how you look at it) that are setup to generalized specifications. Another reason is because they stand behind their products. If you happen to get a set of shocks that are not setup the way you like, TCS / Race Tech will revalve them for free.

Total Control Suspension (TCS) has developed what they call the Sag Control Series (SCS). This is basically what you call Zero Preload. This allows the bike to have a lower ride height (which is crucial in some applications) without losing wheel travel. With this setup, you can corner much faster and increase traction because your center of gravity is lower. The SCS suspension absorbs bumps and obsticals far better because the chassis is basically floating in the center of the suspensions travel. So when the tire encounters a hole, the suspension will allow the tire to drop into the hole without making the chassis drop with it which can (as I am sure most of you know from experience) cause the bike to bump (or as I like to say Catapult) you off. Another improvement with these shocks is the braking ability. With the SCS shocks the tires actually remain in contact with the ground for more than with standard preload shocks. Because of this, you have more control of the quad while braking heavily in the ruts or when you hit the brake bumps on the track. Shock valving is crucial in the performance of any suspension, especially in the SCS shocks. You really feel the benefits of the valving in these shocks when you land your first double. Can you say "PLUSH"?

SCS or Zero Preload suspensions are definately a must in most racing applications.
