Series 412 Shock Absorber without Covers – Progressive Suspension (Ref. 412-4044C)
Specifically designed for Harley models, the Series 412 shock absorbers provide a robust and economical solution to solidify the suspension of your touring or classic bike. Steel body with gas charge and internal reservoir for consistent damping of irregularities. Spring preload adjustment via cam in 5 positions to quickly adapt the handling according to rider, passenger, or luggage.
A few practical points: a different length from the original may slightly alter the rake angle and the responsiveness of the steering. On some XL models ('86‑'15), an adjustment or spacer for the chain/belt guard may be necessary to maintain proper clearance. Before installation, check the travel and clearances (swingarm, exhaust, chain/guard, tyre).
Common applications: Harley Dyna and vintage/touring bikes — for example FXDLS 1800, FXDWG 1690, and FXDL 1690. Consult the most recent homologation certificate if necessary.
