Progressive Suspension 00-17 Fxst/Flst 422 Series Shocks With RAP

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

Before purchasing or attempting to install shocks that are different than the OEM length, confirm that your wheel travel can be altered without causing clearance issues such as, swingarm/axle to exhaust contact as well as chain/belt guard or tire contact.

Heavy Duty Applications are recommended for bikes operating at or near the manufacturer's maximum load rating over 50% of the time.
