Description for Progressive Suspension Fork Spring Kit 

Progressive Suspension Fork Spring Kit

• The ′Original′ 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

• Lifetime fork springs warranty

• 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 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

• Sold in sets that include correct spacers for the application

Customer Reviews for Progressive Suspension Fork Spring Kit 

Overall Rating:
5/5 based on 1 rating

I'm very impressed by the performance. I can actually feel my suspension working now, whereas the stock springs always felt stiff. However, these still will prevent excessive dive when stopping. If you're on a late model Harley Sportster, I recommend having the dealer install them. You will not be able to tension the spring and seal the left fork (the one with the damping rod & cartridge) without the proper tools. Take your fork in, and it'll cost about $50, give or take.
