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
PROGRESSIVE SUSPENSION 422 Series Shocks With RAP, Harley 00-15 FX 00-15 FL
The Softail chassis has long been a challenge as the shocks are hidden under the frame which makes common adjustments difficult
The RAP (Remote Adjustable Preload) system allows for easy tuning of the shocks to account for changing loads or the addition of a passenger and is conveniently located behind the left passenger peg
Simply turn the knob in either direction to set the spring preload

PROGRESSIVE SUSPENSION Black 412 Cruise Series Shocks, Harley 86 - 15 XL
The perfect balance of lowered stance and ride quality
Combine a flat-wire spring with a progressive main spring, the 12.5" shock sits like 11.5" units under the weight of the bike, yet utilizes the full stroke as terrain demands it
The result is a lowered shock that rides like a traditional height unit
