Installation tips: some or all of the listed shock absorbers may be road-legal – check the most recent certificate for your reference. On Sportster XL ('86–'15), installation may require modification or addition of spacers on the chain/belt guard to ensure clearance. A shock absorber that is slightly longer or shorter than the original may alter the rake angle and, consequently, the steering responsiveness. Before installation, check the travel and clearances (swingarm, exhaust, chain/guard, tyre).

Compatibility (examples): Harley Davidson XL 1200 (Sportster Forty-Eight, Forty-Eight Special, Superlow) – 2020 models listed as common uses.
