Progressive Suspension 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. 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.

Features:

Progressive spring rate
High-quality chrome-silicon wire
Precision wound
Made in USA
