Progressive Fork Springs For Harley
The 'Original' Progressive-rate fork springs soak up small road bumps, yet are firm enough to absorb the molar-rattlers. 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. A progressive-rate spring has the advantage of a resistance to compression that rises as the spring is being compressed - it gets tougher to compress as it is compressed. 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. Progressive Heavy-Duty Spring Kits as well as Lowering Spring Kits are also available.
