- Race Tech's answer to the linkless PDS system
- Easy fix for the problem of rear suspension being too harsh and too easy to bottom
- Progressive spring gives more resistance to bottoming and supplies a plusher ride
- Made from chrome silicon spring steel, shot-peened, heat-treated and preset to prevent sacking
- The rates get stiffer as the numbers go higher.
