Points of attention: some or all shock absorbers in the range may be road-legal — please check the most recent certificate. A shock absorber that is slightly longer or shorter than the original may alter the rake angle and steering behaviour. On certain XL models ('86-'15), spacing or modification of the chain/belt guard may be necessary to ensure clearance. For frequent use near maximum load, consider the Heavy Duty versions.

Compatibility examples: Harley-Davidson FXDLS 1800 (2017), FXDWG 1690 Wide Glide (2017), FXDL 1690 Low Rider (2017).
