Steel construction, chrome body, and internal reservoir with gas-charged damping for consistent performance on varied roads. Spring preload adjustment via a 5-position cam for quick adaptation of the suspension to the rider, passenger, or load.

Installation and usage notes: the different length from OEM may slightly alter the rake angle and handling (longer = sharper steering, shorter = slower steering). On certain XL models ('86-'15), an adjustment or spacer for the chain/belt guard may be necessary to ensure clearance. For frequent use close to maximum load, prefer Heavy Duty variants. Check for travel possibilities and clearances (swingarm, exhaust, chain/belt, tyre) before installation. Some or all of the listed shock absorbers may be road-legal; check compliance for your model.

Frequently compatible applications: Harley Davidson FXDLS, FXDWG, FXDL (Dyna models 2017 and similar).
