True high performance front suspension is finally available for the 2014 and newer HD Touring line. 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 for the late model baggers. The asymmetrical layout places a progressive rate spring in one leg and an aluminum bodied, sealed cartridge damper on the other. The result is superior damping via the internal bypass of the FST valve, increased ride control and a new benchmark for high performance front suspension. Monotube cartridge style damping improves ride comfort, resistance to front brake dive as well as improving front end stability, cornering and bottoming control. No mods or special tools are required for install. Available in stock or lowered version. Check it out on their website, or contact your local Progressive Suspension dealer for more information.
