PROGRESSIVE SUSPENSION 422 Series Shocks, Harley 89-99 FX 89-99 FL
Fully adjustable for ride height and spring preload
Tune suspension to match riding style
Shocks feature a show chrome cover
Pair of progressive-rate coil springs and purpose-designed monotube dampers provide superior suspension performance
Dampers feature a nitrogen charge that eliminates internal oil cavitation and helps create a consistent ride while resisting heat-induced fade
Shocks can be adjusted up to 2" lower than stock
RAP (Remote Adjustable Preload) system allows for easy tuning of shocks to account for changing loads or the addition of a passenger with a remote preload adjuster
PROGRESSIVE SUSPENSION Monotube Cartridge Fork Kit, Harley 06-15 FX
Asymmetrical design places a preload adjuster over a progressive rate spring in one leg and an aluminum-bodied, sealed cartridge damper on the other; providing superior damping and ride control combined with tunable preload and a new benchmark for high performance suspension
Improves resistance to front brake dive, front end stability, cornering and bottoming control
Adjustable to standard length or to lower the front end up to 1"
A Progressive Suspension rate spring has the advantage of a rising rate resistance to compression
The benefit is the spring can be soft enough at the start of the travel to offer a "plush" ride, yet firm enough at the end of the travel to soak up the big bumps
Spring rates have been chosen to reduce front-end dive during braking, yet still provide excellent ride comfort
