Progressive Rate Fork Springs - Harley-Davidson
About Progressive
Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Upgrade your Harley-Davidson's front suspension with Progressive Fork Springs, engineered with progressive rate technology. These springs are designed to absorb small road bumps smoothly while providing firm support for larger impacts.

Common questions
What is the main benefit of Progressive Rate springs over standard springs?
Progressive Rate springs offer a dual advantage: they start soft to absorb minor road imperfections for comfort, then progressively stiffen to provide robust support for larger impacts and heavy braking.
Will these springs help reduce the front-end dive I experience during hard braking?
Yes, these Progressive Rate fork springs are specifically engineered to reduce excessive front-end dive, providing more stability and control during hard braking maneuvers.
Do these fork springs require any other modifications for installation?
These springs are designed as a direct replacement for your stock fork springs. However, fork disassembly and proper reassembly with new fork oil are typically part of the installation process.
