- Unique Ultra touring spring configuration provides the superb ride quality and suspension travel of a 13” shock but the custom lowered look of a 12” shock
- Ultra Low Series shocks are designed to sit even lower; 2” lower than a stock Touring model
- With the QPS upgrade kit installed on 444 Series and 944 Series shocks, it’s no longer necessary to take saddlebags off to adjust the sag when going from a single rider, to a two up riding configuration, and then back to a solo riding experience
- QPS upgrade kit utilizes a sealed gear drive to smoothly adjust preload and offers the same range of preload adjustment as the original 444 or 944 series shock when it comes from the factory
- Built around Progressive Suspension’s Frequency Sensing Technology (FST)
- Allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality
- 944 FST Ultra Touring shocks are available in three configurations: Standard (Up to 250 lbs.), Heavy-duty (250 to 350 lbs.) and Super heavy-duty (350+ lbs.)
- Unique spring combination delivers a lower rider height while being ridden or on a side stand, allowing you better control both at intersections and when parking
- Adjust spring preload by hand; no special tool needed
- Progressive rate mainsprings specifically designed for touring models
- High-pressure gas charged for consistent performance
- Made in the USA
- Super heavy-duty applications are recommended for bikes operating above the manufacturer’s maximum load rating over 50% of the time.
- 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.
