Progressive's asymmetrical design places a preload adjuster over a progressively wound spring in one leg and an aluminum bodied, sealed cartridge damper on the other. This design results in superior damping and ride control combined with adjustable preload and a new standard for high performance suspension. It can even be installed in either a standard configuration or 1" lower.
