For 99-19 FLT/FLHT/FLHR/FLTR/FLHX (except H_D Trike). Standard. 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. Built around Progressive Suspension's Frequency Sensing Technology (FST). The 944 Ultra Touring shocks are available in three configurations: Standard (Up to 250 lb.), Heavy-duty (250-350 lb.) and Super Heavy Duty (350+ lb.). Allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality. Unique spring combination delivers a dropped ride height while being ridden, but also while the bike is on a side stand. This allows you to better manage your bike 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 U.S.A. NOTE: Super Heavy Duty Applications are recommended for bikes operating above the manufacturer's maximum load rating over 50% of the time. NOTE: 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. - Part Number - 1310-0904
