Progressive Suspension Fork Spring Kit

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.
