422 Series shock absorbers with remote adjustable preload

The Softail chassis has always been a challenge, as the shock absorbers are hidden under the frame and make conventional adjustments difficult
The RAP (Remote Adjustable Preload) system allows easy adjustment of shock absorber preload according to load or passenger presence, and is located behind the passenger's left footrest.
Simple preload adjustment by turning the knob in either direction
Before purchasing or installing shock absorbers of a different length to OEM, confirm that the wheel travel can be modified without causing space issues, such as contact between swingarm/axle and exhaust, or between chain/belt guard and tyre.
Heavy Duty applications recommended for motorcycles operating at the manufacturer's maximum load limit more than 50% of the time.
