Progressive Fork Springs For Harley

Progressive's 'original' progressive rate fork springs, designed soak up the small road bumps and improve front end stability and comfort.

Features:

  • Progressive rate fork springs soak up the small road bumps, yet are firm enough to absorb the molar-rattling ones
  • Spring rates have been chosen to reduce front end "dive" during braking, yet still provide excellent ride comfort
  • Progressive Rate Fork Springs have several advantages over straight rate springs, advantage of a rising rate resistance to compression this helps in varying road conditions from small road imperfections to pothole filled roads
  • The benefit of this is progressive spring rate is that the spring can be soft enough at the start of the travel to offer a "plush" ride, yet be firm enough at the end of the travel to soak up the big bumps
  • Ideal performance improvement when installing chrome lower forks
  • They eliminate sag, reduce nose dive under braking, improve stability and increase ride comfort
  • Lifetime fork spring warranty
  • Sold in sets that include correct spacers for the application

Fitment Notes & Exceptions
  • Changing ride height can potentially change many carefully-engineered attributes of your bike, including trail and mechanical trail
  • A change in ride height at one end of the vehicle usually will require a change at the other end
  • Heavy Duty shocks are recommended for bikes operated at or near the OEM maximum load rating over 50% of the time
  • Prior to purchasing springs that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues - common interference spots include triple trees, fenders, frame, and of course, the ground
