True high performance front suspension is now available for the M8 Softail models with 49mm front ends. Progressive Suspension has combined their road smoothing Frequency Sensing Technology (FST) damper with a progressive rate spring to create a state-of-the-art fork cartridge kit. The asymmetrical design places a preload adjuster over a progressive rate spring in one leg and an aluminum monotube, high pressure, nitrogen charged, sealed cartridge damper on the other. The result is superior damping and ride control combined with tunable preload establishing a new benchmark for high performance suspension on the 49mm M8 Softail platforms. Standard ride height or 1"-2" lowered versions are available.

  • 1”-2” lower ride height
  • High pressure nitrogen charged FST damper
  • Improved handling and stability
  • Threaded preload adjuster with 11 full turns of adjustment
  • Progressive rate spring
  • Deflective disc technology
  • Preload ½” Allen wrench included
