Progressive Suspension — Series 412 Shock Absorber (manufacturer part number: 412-4065B)

Designed to equip Harley-Davidson motorcycles, this Series 412 shock absorber provides a robust and straightforward solution to restore control to your rear end without unnecessary complexity. Subtle black finish, steel body, and internal reservoir: a discreet installation that respects the roadster aesthetic while remaining road-ready.

• Function: Standard, gas-charged for stable and progressive response.
• Extended Length: 330 mm (13.00") — measured centre to centre of eyelet.
• Adjustment: spring preload via a 5-position cam to adapt the stance according to rider, passenger, or luggage.
• Material: steel, black finish. Internal reservoir for a compact look.
• Manufacturing: made in the USA, available in chrome or black versions depending on part numbers.

Ideal for riders looking to improve handling, damping consistency, and feel at the handlebars without radically altering the motorcycle. Please pay attention to checks before installation: consult the latest compliance certificate for road legality and check clearances (chain/protection, exhaust) — on some Sportster models (XL '86-'15) spacing or modification of the chain/belt guard may be necessary. A change in length may slightly alter the rake angle and steering responsiveness.
