412 Series Shock Absorber without covers from Progressive Suspension, designed for Harley and suitable for Vintage/Classic and Touring categories. Discreet black finish, steel construction, and robust design: this gas-charged shock absorber with an internal reservoir offers a durable solution to replace or upgrade the rear suspension without decorative parts (model delivered without caps).
Designed for riders who want a discreet and reliable shock absorber, this model can slightly alter the rake angle depending on whether it is longer or shorter than the original (impact on steering responsiveness). During installation, check clearances (swingarm, exhaust, chain/belt guard, tyre) — on some XL models ('86‑'15) spacing or modification of the chain/belt guard may be necessary. Some shock absorbers in the range are road-legal: check the latest certification for the updated list.
Application examples: Harley Davidson FXDLS 1800 (2017), FXDWG 1690 (2017), FXDL 1690 (2017).
