True high performance front suspension is finally available for the 2017+ M8 Softail line with 49mm front ends. Yes again, we've gone back to the drawing board and created a state-of-the-art Fork Cartridge Kit designed to outperform everything on the market. The asymmetrical design places a preload adjuster over a progressive rate spring combined with our road smoothing Frequency Sensing Technology (FST) damper for Milwaukee Eight Softail models.
