True high-performance adjustable front suspension is finally available for Harley Dyna models. Progressive Suspension has gone back to the drawing board and created a state-of-the-art High Performance Fork Cartridge Kit designed to outperform everything on the market. The asymmetrical design places a preload adjuster over a progressive rate spring in one leg and an aluminum bodied, sealed cartridge damper on the other. The result is superior damping and ride control combined with adjustable preload and a new benchmark for high performance suspension on the Dyna platform. Can be installed in either standard configuration or 1" lower.
