• Extended length: 305 mm (12.00") — centre to centre measurement
• Preload adjustment via cam with 5 positions to adjust ground clearance and load handling
• Finish: black (without covers) — discreet style suitable for Vintage/Classic and Cruiser/Touring environments
• Function: standard; material: steel; damping: gas

Suitable for many Harley models (notably Dyna such as FXDLS, FXDWG, FXDL 2017 indicated as examples). Before installation, check the clearance of the swingarm, exhaust, and chain/belt guard: on some XL '86-'15 models, a spacer or modification of the chain guard may be necessary. A shock absorber longer or shorter than the original may slightly alter the rake angle and steering responsiveness. For frequent use at full load, prefer the "Heavy Duty" application.
