Series 412 Shock Absorber without Covers (manufacturer part no. 412-4068B) — Progressive Suspension offers a simple and robust shock absorber designed to enhance the suspension of Harley motorcycles in an economical format. Black finish, steel tube, and internal reservoir: a sober and reliable choice for roadsters seeking improved handling without complications.
- Type: Gas-charged shock absorber, standard function.
- Adjustment: 5-position cam spring preload for quick adjustment based on load and riding style.
- Extended length: 305 mm (12.00"). All shock absorbers are measured centre to centre of the eyelet.
- Material / finish: Steel, black finish.
- Manufacturing: Made in the USA.
Some models from the 412 series are road-legal — check the manufacturer's certificate for the most recent list. Note: installation on certain models (notably XL '86-'15) may require modification or spacing of the chain/belt guard to ensure clearance. A shock absorber that is slightly longer or shorter than the original may also alter the rake angle and thus the responsiveness of the steering.
Particularly suitable for Sportster and Harley roadsters (e.g. XL 1200 Forty-Eight / Superlow 2020). Before purchase or installation, check the useful travel and clearances (swingarm, exhaust, belt/chain guard, tyre) for a risk-free installation.
